What ETFs are & how they work
Start here: what an ETF actually is, the main types, and how they work under the hood.
An ETF is a single investment you buy like a share, but it holds many companies or bonds at once — so one purchase spreads your money across a whole market instead of a single stock. Most beginners start with a broad, low-cost index ETF.

Is an ETF the same as a stock?
No. A stock is one company; an ETF is a basket that can hold hundreds of them in a single purchase — that spread is the whole point.
Do I need a lot of money to start?
Not really. Many ETFs cost tens of euros per share, and a savings plan lets you put in small amounts each month.
Are an ETF and an index fund the same thing?
Almost. An index ETF trades on an exchange like a share; a traditional index fund is bought from the provider and priced once a day.
