What are ETFs? Simply explained

An ETF (Exchange Traded Fund) is an investment fund you buy and sell on the stock exchange like a single share. Instead of one company, one ETF share gives you a small slice of many companies at once.

How an ETF works

Most ETFs track an index – for example the S&P 500 (500 large US firms) or the MSCI World (around 1,400 firms across 23 developed markets). Buy an MSCI World ETF and your money sits proportionally in all of them, weighted by size.

The ETF is passively managed: it simply copies the index instead of paying an expensive manager to pick stocks. That is what makes ETFs cheap.

Why ETFs are popular

• Broad diversification: one world ETF spreads risk across 1,000+ firms.
• Low cost: ongoing fees (TER) are often 0.10–0.25 % per year.
• Simple & transparent: you can always see the holdings – on Alysly for every ETF.
• Flexible: trade any time markets are open, or via a savings plan.

What is actually inside?

Every ETF page on Alysly shows the top holdings, sector and country breakdown – and the comparison shows how much two ETFs overlap.

Here is a real example – the actual current composition of the MSCI World:
