An ETF (exchange-traded fund) is a fund you can buy like a share on an exchange. One ticket can hold hundreds of stocks or bonds — instant diversification without picking each name.
How an ETF works
- The fund holds a basket of assets (e.g. global large companies).
- You buy units/shares of that fund through a broker.
- The price moves through the trading day (unlike many mutual funds that price once daily).
Physically replicated ETFs hold the underlying securities; some use sampling or derivatives. For beginners, broad, UCITS equity/bond ETFs from large providers are usually the starting point in Europe.
Why they’re popular with long-term investors
- Diversification in one line
- Typically low ongoing fees vs active funds
- Transparent holdings
- Easy to rebalance (buy/sell one ticker)
