What an ETF is, and why most new investors should start there

Imagine buying a slice of 1,600 different companies — Apple, Nestlé, Samsung, Toyota — in a single click, for less than €100. That is not a pitch. It is an ETF, and it is probably the most useful financial instrument available to someone starting out today.

Yet most people never get past the acronym. This article is here to fix that.

What ETF actually stands for

ETF means Exchange Traded Fund: a fund you buy and sell on a stock exchange, the same way you would a share. The difference from buying a single share — which ties your money to one company’s fortunes — is that an ETF holds dozens, hundreds or thousands of different holdings at once.

The mechanism is simple: an ETF tracks an index. An index is a list of companies selected by defined rules. The most widely followed in the world is the MSCI World, which covers the major listed companies of developed markets — roughly 1,400 holdings across 23 countries. Buy an ETF tracking the MSCI World and you own a slice of all of them, weighted by their size in the index.

You don’t pick winners. You don’t forecast. You buy the market.

What an ETF costs

Traditional funds sold by banks and insurers typically charge between 1% and 3% a year. On €10,000 invested over 20 years, a 2% annual fee costs you more than €8,000 in foregone returns. That is not a typo, and it is the single most expensive thing most savers never notice.

ETFs cost far less. The annual management fee — the TER, or Total Expense Ratio — usually falls between 0.07% and 0.30% for common products. On €10,000, that is €7 to €30 a year rather than hundreds.

The reason is structural. An ETF has no human manager deciding what to buy. It follows the index mechanically. Less human labour, lower cost.

ETF versus actively managed fund

An actively managed fund employs analysts who decide daily what to buy and sell, aiming to beat the market. The trouble is the record: over the long run, most active funds fail to beat their own benchmark once fees are deducted. SPIVA research has found that more than 90% of active European funds underperform their reference index over 15 years.

You pay more, and you tend to get less.

How you actually buy one

You need an account with an online broker — a platform that gives you access to the markets. Opening one takes ten or fifteen minutes from your phone with an identity document.

Once the account is open, you search for the ETF by its ISIN, a twelve-character code that identifies the exact product. This matters more than the name: the same strategy is often sold in several versions, and the ISIN is what removes the ambiguity. Enter how much you want to buy, confirm the order, done. Some ETFs trade for less than €10 a unit.

If you are resident in Italy, the broker you pick also determines how much tax paperwork you inherit — worth reading about before you open the account rather than after.

What you might earn

Returns depend on the index and, above all, on how long you stay invested. Nothing is guaranteed, and any year can be negative.

That said, assuming a 7% average annual return — broadly in line with the long-run history of global equity markets — investing €100 a month for 20 years would grow to roughly €52,000, on €24,000 of your own money. The gap is compounding, and it is why time in the market tends to matter more than the size of the first payment.
