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 Dvanáctiznakový mezinárodní kód, který jednoznačně identifikuje tuto třídu podílů fondu.

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.

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.
