What is an ETF?

Remember the flea market, where we started? Imagine someone already went through the whole market, picked the best 500 items, and put them in a single basket.

Exactly. You buy the whole basket, in one move. That's an ETF — a "basket" with pieces of hundreds of companies, that you buy as if it were a single thing.

Sort of, but not randomly — usually the basket tracks an index.

You could, but it would take a long time and cost a lot more — fees for every single transaction. Plus, the companies in an index change often — some drop out, others come in — and it would be hard to keep up with all those changes on your own. With an ETF, you pay once, and the basket updates automatically, without you doing anything.

Exactly — that's the idea. You have a tiny piece of each one, you're not putting all your money in one place. If one does poorly, the others can make up for it.

Safer, not guaranteed safe — if the whole market drops, the basket drops too. But you're no longer relying on a single company.

Exactly the same — it has a price, you can buy or sell it any time the market is open, just as simply as a regular stock.

I've only shown you the basics — there's a lot more to discover. There are many types of baskets: accumulating or distributing, based on stocks or bonds, in different currencies, with different costs, focused on a specific industry or region. And you can combine several different baskets, you don't have to pick just one.

Perfect — we'll take them one at a time, separately.
