What is an ETF? A 2-minute beginner’s explainer
An ETF is basically a ready-made basket of investments you can buy in one click — instead of picking shares one by one.

One basket, many companies at once
Instead of buying Apple, then Microsoft, then hundreds more one company at a time, an ETF buys the whole list for you and bundles it into a single thing you can own. One purchase of a broad world ETF can give you a slice of 1,500+ companies at once. Each fund carries a unique Un code international de 12 caractères qui identifie de façon unique cette classe de parts du fonds. More → code, so you always know exactly which one you are looking at. The annotated card above breaks down what every part of a real ETF actually means.
It trades like a single share
The ‘exchange-traded’ half of the name is the clever bit. A traditional fund is priced just once a day; an ETF sits on a stock exchange and trades like a single share, all day long. So buying broad exposure is as quick as buying one stock — one order, one price you can see, and you can sell the same way whenever the market is open.

What an ETF is not
It helps to be clear on what an ETF is not. It is not a single hot stock — that is the whole point, it is a basket. It is not a savings account: there is no fixed interest and no guarantee, and the value rises and falls with the market, so you can get back less than you put in. And it is not a recommendation — we explain how ETFs work so you can judge them for yourself, never which one to buy.
