How much to show
Stage 4 · The Machine
The money building
One company, seen from the corner of the street. Go in through the lobby and take the lift floor by floor; the floor you stop at opens up and its papers come out. Each book you read lights a window.
Every company, person and number here is made up. Not financial advice.
Every business keeps score with three reports. Together they answer: did it make money, where did the cash go, and what does it own and owe?
Three questions
The income statement asks: did the business make a profit over a period, like a year? The cash flow statement asks: where did the actual cash come from and go? The balance sheet asks: what does it own and owe on one day?
A café, for every book on this shelf
Picture a café. It sells coffee and cake, pays rent and staff, and once bought an oven. We follow the same café through all three reports.
Why three
One report hides what another shows. The café can make a profit and still run out of cash, because a big customer pays late, or because it bought a new oven this year. Reading the three together tells the real story.
Why it matters to you
Your own money works the same way. Portfolio keeps your net worth (a balance sheet), what came in and went out (an income statement) and the calendar of money moving (a cash flow).
The income statement shows what came in and what it cost over a period, and what is left: the profit.
The shape
Sales (also called revenue) at the top. Costs below: what was bought, rent, wages, interest, tax. Profit at the bottom. That is why profit is called "the bottom line".
The café's year
The café sold €200,000 of coffee and cake. Everything it cost came to €180,000. Profit: €20,000.
The margin
The margin is the share of each sale that is left as profit. €20,000 of profit on €200,000 of sales is a 10% margin: 10 cents kept from every euro sold.
Profit is not cash
A sale counts when it is made, even if the customer pays next month. A big purchase, like a €10,000 oven that will last 5 years, is counted as €2,000 a year instead of all at once. So profit and cash can be very different.
What to look for
Are sales growing? Are costs growing faster than sales? Is the margin getting thinner? A company can sell more and still earn less.
The cash flow statement follows the actual money: what came in, what went out, and the cash left at the end.
Three kinds of cash
From running the business: customers paying, bills and wages paid. From investing: buying an oven, selling old equipment. From financing: loans taken or paid back, money put in by the owners or paid out to them.
The café's year in cash
The café made €20,000 of profit. But this year it paid €12,000 cash for a second oven, which the income statement only counts a little at a time. So the cash it actually kept was much less than its profit.
Why it catches problems
A business can show a profit and still run out of cash, for example when customers pay late. The cash flow statement is where trouble shows first.
Free cash flow
Cash from running the business, minus what it spends on things like ovens and machines, is called free cash flow: the cash that is really free to pay debts or owners.
For you
Your salary, your loan payments, your card bills and your dividends are your cash flow. Portfolio's Upcoming card is its calendar.
The balance sheet is a snapshot of one day: everything owned, everything owed, and what is left for the owners.
Both sides always match
What is owned (assets) always equals what is owed (debts) plus what belongs to the owners (equity). That is why it is called a balance sheet.
The café on 31 December
The café owns €50,000: ovens, tables, stock and cash. It owes €20,000 on a bank loan. The owners' part, its equity, is €30,000.
Borrowing moves both sides
If the café borrows €10,000 to buy another oven, it owns €10,000 more and owes €10,000 more. Equity does not change. Only profit, or the owners putting money in or taking it out, changes equity.
What to look for
How much is borrowed compared with what is owned, and how much cash there is to pay what is due soon. A balance sheet heavy with debt has little room if sales fall.
The three statements are one story told three ways. Numbers from one show up in the others.
Profit grows equity
The profit at the bottom of the income statement is added to the owners' part (equity) on the balance sheet, unless it is paid out to them.
Cash flow explains the cash
The cash flow statement starts with last year's cash and ends with the cash on this year's balance sheet. Every euro in between is explained.
Timing gaps sit on the balance sheet
A sale not yet paid becomes money owed to the café. A bill not yet paid becomes money the café owes. Both wait on the balance sheet until the cash moves.
Reading them together
Profit rising but cash falling? Look for customers paying late or big purchases. Equity falling with a profit? The owners took more out than the café earned.
You have a balance sheet, an income statement and a cash flow too. Portfolio keeps all three.
Your balance sheet: net worth
Everything you own (investments, cash, a home) minus everything you owe (loans, cards). Portfolio shows it on Overview.
Your income statement: what you keep
Pay and dividends in; spending, fees and interest out. What is left is what you can save and invest.
Your cash flow: the calendar
Salary day, loan payments, card bills and dividends, in date order. Portfolio's Upcoming card shows what is about to move.
Why bother
Most money trouble is a cash flow problem first: a bill arrives before the money does. Seeing your own three reports makes the next step obvious.
Every listed company publishes an annual report. It is long, but you only need to know where to look.
Where to find it
Look on the company’s own site, under Investors. Since 2021 listed companies in the EU publish it in one machine-readable format (ESEF), so the numbers can be read by software as well as by people.
The parts
A letter from the bosses, a report on the year and its risks, the three statements, the notes behind them, and the auditor’s opinion. The statements give the numbers; the notes explain how they were made.
Read the notes
One-off gains, changes in how things are counted, debts that sit outside the main numbers: they are in the notes. When a number looks too good, the note behind it is where the answer is.
The auditor
An independent auditor checks the accounts. A clean opinion says they are fairly presented. Any reservation or doubt about the company carrying on is rare and worth taking seriously.
To remember
Annual reports are on the company’s Investors page.
Statements give numbers; notes explain them.
An auditor’s reservation is a red flag.
Sales are only the top line. Check that profit grew too, not just revenue.
What it is
A shop sells €100 this year and €140 four years later. Its costs go from €90 to €146. It sells 40% more and now loses €6.
Why it happens
Growth costs money: more staff, more space, more ads, lower prices to attract customers. When costs grow faster than sales, each new sale can make the hole deeper.
The numbers
In 2022 Amazon sold $514 billion, up 9% on the year before. Its operating profit fell by half, from $25 billion to $12 billion.
The trap
Headlines love record sales. But big is not the same as profitable. In 2023 Amazon’s shops outside North America sold $131 billion and lost $2.7 billion.
Where you see it
Every annual report starts with sales, then takes away the costs. Put two years side by side: did profit grow as fast as sales?
Profit counts on the day of the sale; cash counts on the day you are paid. Check both, side by side.
What it is
A firm sends a client a €12,000 bill. The profit counts today. The money comes in three months. The wages are due on Friday.
Why it happens
Profit is counted when a sale is made. Cash is counted when money moves. Unpaid bills, and money spent long before its cost is counted, pull the two apart.
The numbers
In 2019 Netflix made $1.9 billion of profit. Its free cash flow was minus $3.3 billion. It paid for shows years before their cost counted in profit.
The trap
Growing fast can empty the bank. Every new order needs cash now and pays back later. A firm full of orders can still run out of money.
Where you see it
In an annual report the cash flow page comes after the profit page. Put profit next to free cash flow. A minus can be building, as with Netflix, but a gap for years needs a reason.
A ratio turns two numbers from the report into one you can compare across years and companies.
Profit margin
Profit divided by sales. A café selling €100,000 a year and keeping €15,000 has a margin of 15%. Rising margins mean each sale keeps more; falling ones can mean rising costs or tougher rivals.
Return on equity
Profit divided by the owners’ equity. €15,000 of profit on €75,000 of equity is 20%. It shows how well the owners’ money is used, but borrowing can push it up, so read it next to debt.
Debt to equity
What the company owes divided by equity. €50,000 of debt on €75,000 of equity is about 0.7. Higher means more borrowed; fine for steady businesses, risky for ones whose sales jump around.
Cash from profit
Cash from running the business divided by profit. Close to 1 or above means profit turns into money. A company that reports profit year after year but little cash deserves a closer look.
Compare like with like
A supermarket and a software firm have very different normal margins. Compare a company with its own past and with others in its industry, never with a single “good” number.
To remember
Margins: how much of each sale is kept.
Return on equity: how well owners’ money works, read next to debt.
Profit should turn into cash.
P/E is the years of today's profit you are paying for. Compare it, never read it alone.
What it is
A company earns €5 for every share. Its share costs €100. €100 ÷ €5 = 20: the price-to-earnings ratio, or P/E.
Why it matters
A P/E of 20 means buying 20 years of today's profit in one go. Paying more years for the same profit is a bigger bet that it keeps growing.
The numbers
Two companies both earn €5 a share. One costs €50 (P/E 10), one costs €100 (P/E 20). If profit never changes, the cheaper one pays back its price in half the time.
The trap
A low P/E is not automatically cheap, and a high one is not automatically dear. A high P/E can be right if profit is about to grow a lot; a low one can be a warning that it won't.
Where you see it
Every stock page shows the P/E next to the price. Comparing it with similar companies, and with its own past, says more than the number on its own.
A share is worth the cash the business will make for its owners over its life. The hard part is that nobody knows that number.
A lemonade stand
A stand makes €1,000 a year, every year. Would you pay €10,000 for it? That is ten years of profit, a return of 10% a year. Pay €20,000 and the return halves to 5%. Price decides the return.
Price to earnings
The price divided by the yearly profit per share is the P/E. A P/E of 20 means paying 20 years of today’s profit. A high P/E bets that profit will grow; it is not cheap or dear on its own.
Later money is worth less
A euro in ten years is worth less than a euro today, because today’s euro could earn interest meanwhile. Valuing a company means adding up its future cash, each year counted for less the further away it is.
Margin of safety
Benjamin Graham, in The Intelligent Investor (1949), asked buyers to leave room for being wrong: pay clearly less than your estimate of value. Estimates are often wrong; the margin is what protects you.
Why many choose an index
Thousands of professionals estimate these values every day, and most of them do not beat the index after costs. Owning the whole market accepts its price instead of trying to beat it.
To remember
The price you pay sets your return.
P/E is years of today’s profit, not a verdict.
Leave a margin for being wrong.
Debt multiplies results both ways. Check how many years of profit it would take to repay.
What it is
A company borrows to buy more than its own money allows. Debt divided by a year's profit shows how many years of profit it would take to pay it all back.
Why it matters
Borrowed money multiplies results. A good year makes the owners much richer; a bad year can wipe them out, because the loan still has to be paid whatever happens.
The numbers
Two companies earn €20 a year. One owes €100 (5 years to repay from profit alone). One owes €300 (15 years). The second is far more fragile if profit drops.
The trap
High debt looks fine while profit is steady. The danger shows up exactly when profit falls, which is also when the company can least afford it.
Where you see it
A company's balance sheet lists its debt; its income statement shows yearly profit. Dividing one by the other takes a minute and says a lot.
A high yield is often a fallen price. Check the payout: a dividend bigger than profit cannot last.
What it is
A share costs €20 and pays €2 a year: 10%. Then the price falls to €10. The same €2 now reads 20%. Nothing got better. The price fell.
Why it matters
A company that earns €1 a share and pays €2 is paying out 200% of its profit. The extra euro comes from savings or loans. That can last a while, not for ever.
The numbers
General Motors paid $2 a share a year from 1997. As its shares fell, that passed 8%, the highest yield in the Dow. In 2006 GM cut it in half, in 2008 it stopped, and in 2009 GM went bankrupt.
The trap
The highest yield on a list looks like the best deal. Often it is the market saying it doubts the dividend. One exception: property funds (REITs) must pay out most profit, so theirs run high.
Where you see it
Walgreens paid a dividend every quarter for 91 years. In January 2024 it cut it by 48%. On any stock page, find the payout ratio: under 100%?
A moat is what stops a copycat from matching success. Ask what it is, plainly, before trusting a good run to repeat.
What it is
A moat is whatever keeps rivals from copying a company's success: a trusted brand, a network only it has, a patent, or being far cheaper than anyone else can manage.
Why it matters
A company with no moat can be copied the moment it succeeds, which caps how long its profits last. A real moat lets good years repeat.
The numbers
A new cola can match the taste and even undercut the price, and still sell a fraction as much, because decades of brand trust don't transfer with a cheaper can.
The trap
A moat is not permanent. Brands fade, patents expire, and technology makes old advantages irrelevant. "It always held up before" is not the same as "it has a moat".
Where you see it
Ask one plain question about any company you follow: why can't a rival simply copy what it does? If the answer is unclear, the moat might not exist.
Before buying one company, answer a few questions in writing. If you cannot, the price is the only thing you know.
The business
What does it sell, and to whom? Why do customers choose it over rivals? Could you explain how it makes money to a friend in two sentences?
The numbers
Have sales and profit grown over five years or more? Does profit turn into cash? Is debt small next to what it earns? Are margins steady or slipping?
The people
Do the bosses own shares? Are their pay and their targets tied to the owners’ results? Have they done what they said in past reports?
The price, and you
What would have to be true for today’s price to make sense? What could break that? If it halved, how much of your money would go? Write the answers down and keep them.
To remember
Write down why, before you buy.
Check the business, the numbers, the people and the price.
Size it by what a halving would cost you.
Debt to assets is the share of what you own that is paid for with debt.
At 25%, a quarter of what you own is borrowed. The higher it is, the less room you have if prices fall.
Leverage is how much you own for each unit of your own net worth.
At 1x nothing is borrowed. At 2x, half of what you own is borrowed, so every rise and fall in prices hits your net worth twice as hard.
Leverage means investing with borrowed money: it multiplies every move the investment makes, up and down, and the loan still costs interest regardless of which way prices go.
How the multiplier works
At 2x leverage (half your own money, half borrowed, say), a 20% rise in the investment becomes about a 40% move on your own money. A 30% fall becomes about a 60% loss on what you put in. The borrowed share does not share the pain; you do.
What it looked like in real life
In March 2021 the family office Archegos Capital Management had built large, heavily borrowed positions through swaps with several banks. When the underlying stocks fell, the banks that had lent against those positions were forced to sell fast, and lost more than $10 billion between them.
The part that is easy to miss
Interest on the borrowed money is due whether the investment rises, falls, or goes nowhere. A flat year on the underlying asset is still a losing year once the loan's cost is taken off.
Where it shows up quietly
Leverage is not only an explicit loan: a mortgaged home, a margin account, or a leveraged ETF held for more than a day all multiply moves the same way, even when nobody calls it "borrowing to invest."
To remember
Leverage multiplies both gains and losses on your own money, not just the investment's own swings.
The loan's interest is owed regardless of how the investment performs.
Forced, fast selling under borrowed positions can turn a market move into a much larger loss, as it did at Archegos in 2021.
Interest cost is what borrowing has cost you so far.
A loan is worth it only if what it pays for earns more than the rate, after tax and risk.
Interest coverage is your gains and dividends divided by the interest on your debt.
It asks whether your investing pays for its loans. Below 1x, you are paying more in interest than your investments returned.
When new bonds pay more, old ones are worth less. The longer the bond, the bigger the fall.
What it is
A bond is a loan you make. You lend €1,000 for 10 years. You get €20 a year, 2%, and your €1,000 back at the end.
Why its price moves
Then rates rise and new bonds pay 4%: €40 a year. Nobody pays €1,000 for your €20 when €40 is on offer. Your bond is fine. Its price has to fall.
The numbers
With 10 years left, your bond sells for about €840 when new ones pay 4%. The €160 less makes up for the smaller payments. If rates fall back, the price climbs again.
The trap
Safe means the payments come. It does not mean the price stays still. The longer the bond, the bigger the fall: with 30 years left, the same change takes it to about €650.
Where you see it
In 2022, Germany’s 10-year bond went from paying below zero to about 2.5%. Older bonds fell in price, and many bond funds had one of their worst years on record.
When interest rates rise, the price of older bonds falls. The longer the bond, the further it falls.
An example
You own a ten-year bond paying 2% a year. Rates rise and new bonds pay 3%. Nobody will pay full price for your 2%, so its price falls until it earns about 3% for a new buyer: to roughly €91.50 for each €100.
Duration
Duration says how much a bond’s price moves when rates move one point. With a duration of 8, a rise of one percentage point cuts the price by about 8%. Longer bonds have longer duration.
2022
In 2022 the European Central Bank raised its rate from −0.5% to 2%. Long bonds that had paid almost nothing lost a fifth or more of their price in a year. Rates had been low so long that many had forgotten bonds can fall.
It works both ways
When rates fall, older bonds paying more become worth more, and long bonds rise most. That is why bonds have often helped when shares fell in a slowdown, though not when inflation was the problem, as in 2022.
To remember
Rates up, bond prices down; rates down, prices up.
Duration tells you roughly how far: duration × the change in rates.
Held to the end, price swings on the way do not change what you get.
The yield to maturity is what a bond earns you each year if you hold it to the end at today’s price.
An example
A bond pays €2 a year and repays €100 in one year. Its price today is €95. Hold it to the end: you get €2 plus a €5 gain on €95. That is about 7.4% for the year, more than the 2% coupon.
Coupon and yield differ
The coupon is fixed when the bond is issued. The yield changes with the price: buy below €100 and you earn more than the coupon; above €100 and you earn less. Newspapers quote yields, not coupons.
A promise, if all goes well
The yield is what you earn only if the borrower pays every coupon and repays at the end, and you hold it that long. A high yield often means the market doubts one of those.
For a fund
A bond fund shows an average yield of what it holds. It is a fair guide to what the fund may earn over the next years, before costs, as long as rates and the borrowers stay where they are.
To remember
Yield to maturity counts the coupon and the pull back to €100.
Price below €100 means yield above the coupon.
A very high yield is usually a warning, not a gift.
Governments in the euro area borrow in the same currency at different rates. The difference is called the spread.
The spread
If Germany’s ten-year bond yields 2.5% and Italy’s 3.5%, Italy pays one percentage point more. Germany is the usual yardstick in the euro area because markets see it as the safest borrower.
What moves it
The spread rises when markets worry about a country’s debt or politics. During the euro crisis, in November 2011, Italy paid about 5.5 points more than Germany. It narrowed as the crisis passed.
Ratings
Agencies such as S&P, Moody’s and Fitch grade borrowers with letters. From BBB− up is called investment grade; below it, high yield. Lower grades pay more because the chance of not being paid back is higher.
For you
A higher yield is payment for a risk. Before reaching for it, ask what you are being paid for, and whether one borrower’s trouble would hurt your plans. Many bond funds hold dozens of borrowers to spread that risk.
To remember
The spread is what one borrower pays above the safest one.
Worry about a borrower widens it.
Higher yield always comes with a reason.
A yearly fee comes off your whole pot every year, so unlike a one-off cost, it compounds against you for as long as you hold.
A worked example
€10,000 growing at 7% a year for 30 years becomes about €76,000 with no fee. Take a 1% yearly fee and it grows at 6% net, ending at about €57,000. The fee alone cost about €19,000: roughly a quarter of the no-fee result.
Why "1%" feels small but isn't
A 1% fee looks tiny next to a 7% return. But it is not taken once: it is taken every single year, including the years the fund barely grows, and it compounds against your money exactly the way a return compounds for it.
The evidence on active funds
S&P's SPIVA scorecards, published regularly for both the US and Europe, consistently find that most actively managed equity funds trail their benchmark index over 10 to 15 years, after fees are taken out. A higher fee does not reliably buy a higher return.
Where to find your own fee
Every EU fund publishes a short official document showing its "ongoing costs" as a yearly percentage. It is the single most checkable number in the fund, because it never depends on how markets perform.
To remember
A yearly fee compounds against you the same way a return compounds for you.
Over 30 years, a 1% fee can take about a quarter of the final result.
SPIVA's regular scorecards find most active funds trail their index over 10 to 15 years after fees.
The cost of fees and interest, as a share of what you invested.
It shows how much of your money goes to others every year. Cutting it is one of the few sure ways to improve a return.
Turnover is how much you sold in a year compared with what you usually hold.
At 100% you replace your whole portfolio in a year. Every sale costs fees, sometimes tax, and is a chance to be wrong.
The yearly fee is on the label. What the fund really cost you shows in how far it trailed its index.
The yearly fee
The ongoing charge (often called TER) is taken from the fund’s value a little every day. You never get a bill: the price is simply lower than it would be. A world index fund often charges between 0.1% and 0.3% a year.
Tracking difference
Compare the fund’s return with its index over a year. If the index made 8.00% and the fund 7.85%, the fund trailed by 0.15 points. That gap, the tracking difference, is the cost you really paid.
Why it can beat its fee
Some funds lend their shares to other investors for a fee, or pay less tax on dividends than the index assumes. Then the gap can be smaller than the yearly fee, sometimes even positive.
Why small numbers matter
Over 30 years, 1% a year takes about a quarter of what you would have had. 0.2% a year takes about 6%. Comparing two funds on the same index, cost is one of the few things you can know in advance.
To remember
The yearly fee comes out of the price; there is no bill.
Tracking difference shows what the fund really cost.
Over decades, fractions of a percent become large sums.
A trade costs more than the commission. Add the spread, the currency exchange and, in some countries, a tax.
Four costs
The commission is what the broker charges per order. The spread is the gap between buy and sell prices. Currency exchange costs something when you buy in dollars with euros. Some countries add a small tax on buying shares.
Currency adds up
A broker that converts at 0.5% takes €5 on a €1,000 buy in dollars, and again when you sell. A fund listed in euros does the exchange inside the fund at bank rates, usually for much less.
Taxes on buying
France and Italy tax buying shares of their larger companies, a fraction of a percent each time. Funds are usually exempt. Your broker’s cost report shows it as a separate line.
Small orders, big share
A €10 commission is 0.1% of €10,000 but 2% of a €500 order. Twelve €500 orders a year at €10 each cost €120, 2% of the €6,000. With fixed fees, fewer and bigger orders cost less.
Cost reports
EU rules make brokers show costs before each trade and in a yearly report, in euros and as a percentage. Read it once a year: it is the clearest picture of what investing costs you.
To remember
Commission, spread, currency and tax: four costs, not one.
Fixed fees weigh most on small orders.
Your broker’s yearly cost report shows them all.
Each country taxes investing its own way, but the same three things come up everywhere: gains, income and holdings.
Three things taxed
Gains when you sell for more than you paid. Income: dividends and interest. And in some countries the holdings themselves, a small share each year. What, when and how much depends on where you live.
Italy
Gains, dividends and interest are taxed at 26%; government bonds of Italy and of countries on a list at 12.5%. Each year 0.2% of the value is due as stamp duty, or as IVAFE on accounts abroad.
Italy’s fund rule
In Italy a gain on a fund cannot be cut by losses on shares, but a loss on a fund can cut gains on shares. Losses can be used in the year and the four after. Portfolio’s tax tool follows this rule.
Germany
Gains and income are taxed at 25% plus a 5.5% surcharge on that tax, about 26.4%, and church tax for members. The first €1,000 a year per person is free, and 30% of a share fund’s gain is not taxed.
Who pays it
Some brokers work out and pay the tax for you. Others leave it to your tax return. In Italy these are called the administered and the declared regimes. Know which yours is before the year ends.
To remember
Gains, income and holdings can each be taxed.
Italy: 26%, 12.5% on many government bonds, 0.2% a year on holdings.
Check whether your broker pays the tax or you do.
A dividend from abroad is often taxed twice: where the company is, and where you live. Part of it can usually be saved.
Taxed at the source
The country of the company keeps part of each dividend before it reaches you. The US keeps 30%, or 15% if your broker has your W-8BEN form, which says you live in a country with a tax treaty.
Reclaiming
Some countries keep more and let you claim part back. Switzerland keeps 35%; with a treaty you can usually reclaim down to 15%, through a form and some patience. Many people find it worth doing only for large dividends.
Then at home
Some countries, like Germany, count the tax kept abroad against your own, up to the treaty rate. Others tax what arrives: in Italy the 26% applies to the dividend after the foreign tax, so both are paid.
Inside funds
A fund also has dividends taxed at the source, and you cannot reclaim it. That is one reason where a fund lives matters: it decides which treaty applies.
To remember
Foreign dividends are usually taxed where the company is first, then at home.
A W-8BEN form cuts US tax on dividends from 30% to 15% for treaty countries.
Inside a fund, the fund’s home decides the rate.
The same fund often comes in two versions: one pays dividends out to you, the other puts them back in.
Two versions
A distributing fund (Dist or Dis in its name) pays its dividends into your account, often every quarter. An accumulating fund (Acc) reinvests them, so its price grows a little faster and nothing arrives.
The return is the same
Before tax, both give the same total return. One hands you the dividends; the other keeps them working. If you would reinvest every payment anyway, the accumulating version does it for you, at no cost.
Tax changes the picture
Where you live decides when tax is due. In Italy an accumulating fund is taxed only when you sell. Germany taxes a small assumed amount every year even if nothing was paid out. Check your country’s rule before choosing.
When paying out helps
If you live on the income, or want to see it land, a distributing fund pays it without selling anything. Some people like that discipline; others prefer not to have to decide what to do with each payment.
To remember
Acc reinvests the dividends; Dist pays them to you.
Before tax the total return is the same.
Your country’s tax rules often decide which suits you.
A fund’s home country is in the first two letters of its ISIN. It can change how much tax is lost on the way.
Read the code
Every fund has an ISIN, a 12-character code. It starts with the country the fund is set up in: IE for Ireland, LU for Luxembourg, FR for France, DE for Germany. Most ETFs sold across Europe live in Ireland or Luxembourg.
Why it matters
The US keeps part of every dividend it pays abroad. A fund in Ireland usually loses 15% of US dividends thanks to a tax treaty; a fund in Luxembourg usually loses 30%. The fund pays it; you never see it.
How much
If US shares pay dividends of 1.5% a year, losing 15% of them costs about 0.2 points a year, and losing 30% about 0.45. On the US part of a world fund, the gap is about 0.2 points a year: as much as a whole fee.
Where to see it
You cannot see this cost on the label. It shows in the tracking difference: two funds on the same index with the same fee can trail it by different amounts because of where they live.
To remember
The ISIN’s first two letters say where a fund lives.
Home country changes how much US dividend tax is lost.
Compare tracking differences, not only fees.
Diversification means not letting one company, or even a handful, decide your whole future.
The study
Hendrik Bessembinder studied every US listed stock from 1926 to 2016 and found that only about 4% of them created all of the stock market's net gain over Treasury bills. More than half of all stocks lost money over their lifetime.
What that means for a single bet
Picking one company to hold for decades is a bet that you found one of that rare 4%. Most people who try do not, not because they are careless, but because so few companies ever turn out to be big successes.
A worked example
Own one company and it goes to zero, and you lose everything. Own 100 companies equally and one of them goes to zero, and you lose 1% of your money. The business risk did not disappear; it got divided.
What it does not fix
Spreading across many shares removes the risk of one business failing, but not the risk of the whole market falling together, as it does in a crash. Diversification lowers one kind of risk, not every kind.
How it is usually done
A broad index fund owns hundreds or thousands of companies in one purchase, which is why it is the simplest way most people diversify: it is certain to own the rare big successes, along with everything else.
To remember
A tiny share of all stocks created almost all of the market's long-run gain; picking one is a bet you found one of them.
Owning many holdings turns "one failure ruins me" into "one failure costs a small slice."
Diversification does not protect against the whole market falling at once.
Largest holding is your biggest position as a share of everything you hold.
If it falls 50%, your portfolio falls by half its share. What it is matters: a world index fund is not one company.
Top 5 holdings is your five biggest positions together.
A high share means your results ride on a few names. Five broad funds can still be well spread.
Cash ratio is cash as a share of everything you hold.
A cushion for spending and for buying chances, or money that is not working. It depends on your plans.
How you split money between shares, bonds and cash decides most of how bumpy the ride is.
What a study found
A 1986 study of 91 large US pension funds found the mix explained about 94% of how their returns moved up and down each quarter. Not 94% of the return itself, as it is often quoted, but most of the ride.
Each part has a job
Shares are there to grow. Bonds are there to steady the whole and to pay. Cash is there to spend and to wait. Change the share of each, and you change both the growth you can expect and the falls you will meet.
See it before you choose
The Lab lets you try mixes on past prices and see each one’s worst fall. Look at the fall, not only the growth: the mix you can hold through a bad year beats a better one you would sell in a panic.
No mix is right for all
Time to your goal, other income, and how you react to losses all change what fits. Nothing here says what yours should be. What matters is choosing it on purpose and writing it down.
To remember
The mix sets most of the ups and downs.
Shares grow, bonds steady, cash waits.
Choose a mix you can keep through a bad year.
Over time your mix drifts. Rebalancing brings it back to what you chose.
How it drifts
You start with 60% in shares and 40% in bonds. Shares rise 30% and bonds stay flat. Now shares are 66% of the total: more risk than you chose, without deciding anything.
Bringing it back
Rebalancing sells some of what grew and buys what lagged, or simply puts new money into the part that is behind. Using new money avoids selling, and so avoids costs and tax on gains.
When
Two common rules: once a year on a set date, or whenever a part moves more than a few points from its target. Checking too often adds costs; never checking lets the mix become something else.
What it does
Rebalancing keeps your risk where you put it. It does not promise more return. It does make you buy what fell and trim what rose, which is hard to do on feeling alone.
To remember
Mixes drift as prices move.
New money is the cheapest way to rebalance.
A simple rule beats deciding by feeling.
Buying a world fund in euros still means owning dollars, yen and pounds. Their moves against the euro become yours.
Where the money is
About seven tenths of a world share index is US companies. Their value is in dollars. If the dollar falls against the euro, that part of your fund is worth fewer euros, even if US shares did not move.
It happens
In 2025 the dollar lost more than a tenth of its value against the euro. A euro investor in US shares saw a good year in dollars turn into a much smaller one in euros.
Hedging
Some funds offer a “hedged” class that removes most currency moves. It costs roughly the difference between interest rates in the two currencies, which can be a point or two a year, and it takes away gains as well as losses.
Over long periods
Over many years currency moves have tended to even out for share investors, but not always and not on any timetable. For money you will spend in euros soon, currency risk matters more.
To remember
A euro-listed world fund still holds foreign currencies.
A weaker dollar lowers your US part in euros.
Hedging removes moves both ways, at a cost.
Volatility measures how big the swings are, up and down, scaled to a year.
It is the standard deviation of daily returns, multiplied by the square root of the days in a year. The stock market has typically swung around 15-20% a year.
It treats a sudden rise as a swing too, which is why Sortino exists.
Below peak is how far you are below your highest point right now.
At 0% you are at a new high. Spending time below the peak is normal; long stretches deep below it are what tests patience.
Max drawdown is the biggest fall from a high to a later low.
It is the worst moment you have lived through as an investor. The stock market fell about 57% from October 2007 to March 2009.
The recovery maths
A fall needs a bigger rise to recover: −20% needs +25%, −50% needs +100%, −80% needs +400%.
Big swings cost you compounded growth even when the average of the ups and downs looks the same, because losses and gains are not opposites once they are multiplied together.
A worked example
Fall 10%, then rise 10%, and €100 does not return to €100: it becomes €99. The two moves average to 0%, but compounding them loses 1%. Fall 30% then rise 30% and €100 becomes €91, a drag of 9%, even though the average of −30% and +30% is still 0%.
Why it happens
A fall and a rise of the same size are not equal and opposite once money is involved, because the rise has to work on a smaller starting amount after the fall. The bigger the swing, the bigger that starting amount shrinks, and the harder the rise has to work just to break even.
Where leverage makes it worse
Leverage multiplies the size of the swings, so it multiplies this drag too. Past a certain point, adding more leverage to something volatile can lower your expected result even if it raises the size of each individual move.
The practical takeaway
A smoother ride is not just more comfortable: it is mathematically worth something, because it loses less to this drag. This is part of why spreading money across different kinds of holdings, which smooths the overall ride, is not merely about feelings.
To remember
A fall and an equal-sized rise do not cancel out; compounded together they leave you below where you started.
Bigger swings create bigger drag, even with the same average return.
Leverage multiplies the swings, so it multiplies the drag, which can lower results past a certain point.
The right amount of risk is the amount you can hold through a bad year without selling.
One company, one rule
If one company is 20% of your money and it halves, you lose 10% of everything. Before buying, ask: if this halved, what share of my money would I lose? Many investors keep any single company small for that reason.
Set your limit before
Decide the biggest fall you could sit through while calm. Portfolio’s “How bumpy is it?” asks for it and compares it with a bad year for your mix. A limit chosen during a fall is usually the wrong one.
Time is a cushion
Money needed in ten years can wait for a recovery; money needed next year cannot. The same fund can be fine for one goal and wrong for another. Match each goal’s money to its date.
The sleep test
If a fall would keep you awake or make you sell, the risk is too high for you, whatever a table says. Lower risk you keep beats higher risk you abandon at the worst moment.
To remember
Size each holding by what its fall would cost the whole.
Choose your fall limit while calm.
Match each goal’s money to its date.
Putting money in all at once or spreading it over months is really a question of time in the market, not timing it.
The study
Vanguard compared investing a lump sum immediately against spreading the same amount over 12 months, across decades of US, UK and Australian data. The lump sum came out ahead in roughly two tries out of three.
Why all at once usually comes out ahead
Markets rise more years than they fall, so money sitting in cash waiting to be spread out is usually missing a rise. Each euro invested earlier simply gets more time to compound.
A worked example
Put €1,200 in on day one of a year the market rises 10% and it becomes €1,320. Spread the same €1,200 evenly over 12 months while the market climbs steadily, and the later instalments buy at higher prices, so the year ends with less than €1,320.
When spreading it out comes out ahead
If prices fall for a while after you start, spreading it out buys some of those later months cheaper, and it is also far easier to live with: no single bad week carries your whole decision.
The real choice
This is a trade between a slightly better expected result (all at once) and a steadier ride while you invest it (spread out). Neither is "wrong"; a large windfall is where the choice matters most.
To remember
Lump sum beats spreading it out more often than not, because markets rise more than they fall.
Spreading it out buys cheaper if prices fall after you start, and feels calmer either way.
The decision matters most for a one-off sum, not for a monthly saving habit.
Market timing means jumping out to dodge a fall and back in before the recovery, and it is far harder than it sounds because the best days and the worst days tend to arrive close together.
The evidence
Recurring studies of the S&P 500 by J.P. Morgan find that missing just the 10 best days over a roughly 20-year stretch cuts the ending value by around half, compared with staying invested the whole time.
Why the best and worst days cluster
Many of the market's best days happen within days or weeks of its worst ones, often right in the middle of a crash, when fear is highest and selling feels safest. A plan that gets you out after the fall often gets you out just before the rebound.
A worked comparison
An investor who stays invested earns the market's full compounded return. One who sells after a scary drop and waits until things "feel safe again" tends to miss much of the recovery, because by the time it feels safe, most of the rebound has already happened.
Why simple rules fail unevenly
A rule like "sell after a 15% fall" can work in a long, slow decline, giving time to get out. It tends to fail badly in a sharp crash that falls and rebounds within weeks, which is exactly the shape many of history's worst and best days share.
To remember
Missing just the 10 best days over 20 years has historically roughly halved the ending result.
The best and worst days tend to cluster together, often inside the same crash.
Simple sell rules can work in slow declines and fail in sharp, fast ones.
The European Central Bank sets the rate that everything else in the euro area is priced from.
One rate
Every six weeks the ECB decides the rate banks earn on money left with it. Banks then lend to each other, to companies and to you at rates built on top of it, so a change reaches loans, savings and bonds.
Why it moves
The ECB raises its rate to slow prices down when inflation is above its 2% aim, and cuts it when the economy is weak and inflation low. It looks ahead, so it often moves before the numbers show the change.
What it does to prices
Higher rates make borrowing dearer, savings more attractive and future profits worth less today. Bond prices fall and shares often struggle. Lower rates do the opposite. Markets react to the surprise, not to what was expected.
Reading it
Portfolio’s World page shows the ECB’s rate next to inflation, with the dates of the next meetings in Coming Up. What markets expect is already in prices; a move that was expected often changes little.
To remember
The ECB’s rate is the base for euro rates.
It rises to cool inflation and falls to support growth.
Markets move on surprises, not on expected decisions.
Prices move on what people expect. On the day of the news, only the surprise is left.
What it is
Big news comes out and the price barely moves. Nothing is broken. It moved already, in the weeks before, when people started to expect the news.
Why it happens
Prices are set by millions of people guessing the future. When a guess becomes likely, they act on it now. On the day, only the surprise part is left to move.
The numbers
On 10 September 2026 the ECB raised its rate by 0.25 points. In France, fixed mortgage rates had gone from 3.44% to about 3.54% before it. In Germany, they did not move on the day.
The trap
Fast is not the same as right. Prices can be wrong, and a few investors have beaten the market for decades. But news you just read is old news to the price.
Where you see it
Next time a headline sounds big, open the chart of the weeks before it. Often the move is already there, and acting on the headline means acting late.
A handful of numbers describe the economy. Each one comes with a date, an expectation and later corrections.
The main ones
Inflation (how fast prices rise), growth (GDP, how much the economy produced), and jobs (how many are out of work). Eurostat publishes a first estimate of euro area inflation at the end of each month and growth about a month after each quarter.
Expected versus actual
Before each number, forecasters publish what they expect. Markets react to the difference. Inflation of 2.5% can push prices down if 2.2% was expected, and up if 2.8% was.
First estimates change
The first numbers are estimates and are often revised later, sometimes a lot. A single month says little; the direction over several months says more.
Use them for context
These numbers explain what is happening around your money. They make poor signals for trading: by the time a number is out, prices have usually moved. Portfolio’s World page keeps ten years of each, so a month can be seen in proportion.
To remember
Inflation, growth and jobs are the core three.
Markets react to the gap with expectations.
First estimates get revised; look at the trend.
Economies grow, slow, shrink and recover. Markets move through these cycles too, but usually earlier, and nobody times them reliably.
The cycle
Growth brings more jobs and spending, then often rising prices and rates, then a slowdown. A recession is a broad fall in activity lasting months. Then it recovers. No two cycles last the same time.
Dated afterwards
In the euro area a committee of economists dates recessions, months after they start and end. While you live through one, you rarely know for sure where you are in it.
Markets run ahead
Share prices tend to fall before a recession is announced and to recover before it ends, because they price what people expect. By the time the news is bad, much of the fall has often happened.
Forecasts
Forecasts of recessions are often wrong in both directions. A plan that works without knowing the next turn, with a mix you can hold, is sturdier than one that needs a forecast to be right.
To remember
Cycles are normal and uneven.
Markets usually turn before the economy does.
A plan that needs no forecast is sturdier.
Cash is not "doing nothing": it earns interest, and that interest is worth the most exactly when stocks are struggling or when interest rates are high.
A real example
In 1980, US inflation ran at about 13.5% a year, and short-term Treasury bills (very safe, very short loans to the government) paid over 10% a year. Cash was not exciting, but it was far from useless.
Why it shifts
What cash pays follows the interest rates central banks set, which rise when they are fighting inflation and fall when they want to support a weak economy. In the 2010s, with rates near zero across much of Europe, cash paid close to nothing; that is a choice by the central bank, not a law of nature.
What cash is for
Over long stretches, broad stock markets have usually beaten cash, but not in every single decade, and never on a guaranteed timetable. Cash's real job is money you will need soon, or a cushion that lets you avoid selling investments at a bad moment.
The trap in the other direction
Treating cash as permanently "safe" ignores that it still loses to inflation when prices rise faster than its rate pays, the same shrinking-in-what-it-buys problem every saver faces.
To remember
Cash's return follows interest rates set by central banks, not a fixed amount.
In 1980s conditions cash could pay over 10% a year; near-zero rates make it pay almost nothing.
Cash's main job is money needed soon or a cushion, not necessarily growth.
UCITS is the EU’s rulebook for funds sold to the public. The KID is the three-page summary every one of them must give you.
What the rules ask
A UCITS fund must spread its money: no more than 10% in one company, and the holdings above 5% may add up to 40% at most. A separate bank, the depositary, keeps the fund’s assets and checks the manager.
The KID
The Key Information Document is at most three pages: what the fund does, a risk number from 1 (low) to 7 (high), what it costs each year, and what you could get back in good and bad years.
Read the risk number well
The risk number mostly measures how much the price has swung. A world share fund is usually 4 or 5. It does not tell you how spread out a fund is, or whether it fits your plans.
Why US funds are missing
Funds listed in the US do not publish a KID, so brokers in the EU do not sell them to ordinary investors. European funds that follow the same indexes fill the gap.
To remember
UCITS funds must spread their money and keep it with a separate bank.
Every fund gives a KID: what it does, its risk number, its costs.
The risk number is about swings, not about whether the fund suits you.
A fund can follow its index by owning the shares, or by a contract with a bank that pays the index’s return.
Physical
A physical fund buys the shares in the index. With a big index it may buy a large sample instead of every one. What you own is a slice of real companies, held by the fund’s depositary.
Synthetic
A synthetic fund owns a basket of other assets and has a contract (a swap) with a bank that pays the index’s return in exchange. It can follow some indexes more cheaply, or save tax on some dividends.
The extra risk
If the bank fails, the fund keeps its own basket but may lose what the bank owed. EU rules cap what a fund may be owed by one bank at 10% of its value, and most swaps are reset often to keep it smaller.
Lending shares
Physical funds may lend shares to others for a fee, against collateral. It earns a little and adds a small risk. The fund’s website shows how much is lent and what it holds as collateral.
To remember
Physical funds own the shares; synthetic ones own a contract.
Synthetic adds a capped risk on the bank behind the contract.
Both can follow an index closely; compare cost and tracking.
Buying an ETF is buying a share. A few habits keep the hidden costs small.
Watch the spread
An ETF’s spread is widest when the market has just opened and when the markets of the shares inside are closed. A fund of US shares is usually cheapest to trade in the European afternoon, when New York is open too.
Use a limit
Exchanges publish a live estimate of what each ETF’s holdings are worth (the iNAV). A limit order close to it keeps you from paying a bad price on a quiet day.
Currency of the listing
A world fund can be listed in euros, dollars or pounds. The listing currency changes nothing about what you own: the fund still holds US, Japanese and European shares. It only decides whether you exchange money to buy it.
One ticker per exchange
The same fund may have a different ticker on each exchange. The ISIN stays the same everywhere, so search by ISIN. Buying where it trades most often gives the smallest spread.
To remember
Trade when the markets inside the fund are open.
A limit order near the iNAV avoids bad prices.
The listing currency does not change your currency risk.
If your broker fails, your shares are still yours. Knowing why, and where the limits are, is worth ten minutes.
Kept apart
EU rules make a broker keep clients’ shares apart from its own. The shares are recorded at a central depository (Euroclear and Clearstream are two big ones). If the broker goes bust, they are handed back or moved to another broker.
If something is missing
If shares or cash cannot be handed back, for example after fraud, an investor compensation scheme pays at least €20,000 per person in every EU country. It covers missing assets, never a fall in prices.
Cash is different
Cash waiting at a broker may sit at a bank. Bank deposits are covered up to €100,000 per person per bank. Read where your broker keeps cash; some spread it over several banks or money market funds.
Check the licence
Every broker serving you must be authorised in the EU. Look it up in the register of its home regulator: CONSOB in Italy, BaFin in Germany, AMF in France. A firm that is not there should not get your money.
To remember
Your shares are held apart from the broker’s own.
Compensation covers missing assets, at least €20,000, never losses from prices.
Check a broker in its regulator’s register before you send money.
Retirement income in Europe usually comes from three places, called pillars. Knowing yours shows how much is left to you.
The three pillars
The first is the state pension, paid from today’s workers’ contributions. The second is a workplace plan. The third is your own saving. Each country leans on them differently.
Why the third grows
Europe is getting older: fewer workers pay for each pensioner. Many countries have raised retirement ages and linked pensions to contributions, so the state part replaces less of a salary than it did.
In Italy
Employers set aside 6.91% of gross pay each year as TFR. A worker can send it to a pension fund, often with an employer top-up. Contributions cut taxable income up to a yearly limit, and the payout is taxed at 15%, falling to 9%.
Across borders
Since 2022 the EU has a Pan-European Personal Pension (PEPP) that can move with you between countries. Few providers offer it so far, but it shows where pensions are going.
To remember
State, workplace and personal: three pillars.
The state part is shrinking as Europe ages.
Workplace plans often come with tax help and employer money.
Insurance protects against losses you could not afford. Many policies sold as investments are something else, and it helps to know who is paid.
What it is for
Insurance is worth it for losses that would wreck your plans: being sued, a serious illness, your family losing your income. Small losses you can pay yourself are usually cheaper to carry than to insure.
Protection or investment
Term life insurance pays only if you die during the term, and is cheap for that reason. Investment policies mix a fund with some cover. Their KID shows the total yearly cost; compare it with a plain fund.
Who is paid
Many sellers are paid by commission from the product they sell. EU rules make them tell you, but it is easy to miss. Ask plainly: how are you paid for this, and how much over the years?
Before you sign
Read the KID, the cost of leaving early, and what is and is not covered. A policy that is hard to leave for ten years should be very good to deserve it.
To remember
Insure what you could not afford to lose.
Investment policies: read the total yearly cost in the KID.
Always ask how the seller is paid.
XIRR is your average return per year, taking into account when each amount went in and out.
If you put money in at different times, a simple "gain divided by money in" is misleading: money added last month has not had a year to grow. XIRR weights each amount by how long it was invested.
Why Portfolio waits a year
Turning a few weeks of results into a yearly rate gives wild numbers. Until your portfolio is a year old, Portfolio shows the total return instead.
Time-weighted return measures the investing alone, with deposits and withdrawals taken out.
It chains together each day's return as if no money came in or went out. That makes it fair for comparing with an index or a fund over the same dates.
TWR or XIRR?
TWR judges your choices; XIRR judges what happened to your money, timing included. If you added a lot just before a fall, your XIRR is lower than your TWR.
Yield on cost is the last 12 months of dividends divided by what the holdings cost you.
It rises as companies raise their dividends on shares you bought cheaper. It says nothing about whether the price went up or down.
The Sharpe ratio is the return above a safe deposit, divided by volatility: reward per unit of swing.
Two portfolios with the same return are not equal if one swung twice as hard. Sharpe puts them on one scale. William Sharpe introduced it in 1966.
Reading it
Below 0, a safe deposit did better. Around 0.5 is ordinary for stocks over long periods; above 1 is good; above 2 is rare and usually means a short or unusually calm history.
Its blind spots
It counts big jumps up as risk, it assumes swings are evenly spread, and over a short period one lucky stretch dominates.
The Sortino ratio is like Sharpe, but only falls count as risk.
Investors fear losses, not upside surprises. Sortino divides the return above a safe deposit by the swing of the down days only.
When Sortino is much higher than Sharpe, most of the swing was upward.
The Calmar ratio is the yearly return divided by the max drawdown.
It asks how much you earned for the worst pain. Terry W. Young introduced it in 1991 for fund managers, usually over three years.
Sales in profit is the share of your sales that made money.
On its own it says little. Someone right 80% of the time can still lose money if the losses are much bigger than the gains.
Average gain vs average loss is your average gain divided by your average loss.
With an average gain twice the average loss, you can be wrong two times in three and still break even. The share of sales in profit needed to break even is 1 ÷ (1 + average gain vs average loss).
Gains vs losses is everything gained on sales in profit divided by everything lost on sales at a loss.
Above 1, the gains paid for the losses. It combines the share of sales in profit and the size of gains and losses into one number.
