Getting started and index basics
A brief note on ETFs
3 min
An ETF (Exchange-Traded Fund) is a fund that trades on the exchange exactly like a single stock — you buy and sell it through your home broker with a ticker, in market hours, using the same order types you just learned.
What sits inside
Most ETFs hold a basket of assets designed to track an index. Buy one share of an Ibovespa ETF and, in effect, you own a tiny slice of every stock in the Ibovespa at once. Buy an S&P 500 ETF and you own a sliver of 500 US companies in a single trade.
Why beginners like them
- Instant diversification — one purchase spreads your money across dozens or hundreds of companies, instead of betting on one.
- Simplicity — no need to pick individual winners; you ride the whole market.
- Low cost — index ETFs typically charge small annual fees.
- Tradability — they trade all day at a live price, unlike traditional mutual funds.
Brazilian and US examples
On B3 you will find ETFs such as BOVA11 (tracks the Ibovespa) and IVVB11 (tracks the S&P 500, giving Brazilians dollar-market exposure in reais). In the US, broad ETFs track the S&P 500 and other indices.
Where to go deeper
ETFs are a big topic — types, how tracking works, fees, and how they fit a portfolio. We give them a full treatment in a dedicated track. For now, simply know that an ETF is the beginner-friendly bridge between one stock and the whole market, bought with the very same skills you have built here.
Related areas also live in their own tracks: detailed company valuation, FIIs (Brazilian real-estate funds) in the reits-fiis track, and buying foreign stocks and BDRs in the investing-abroad track. This track has given you the foundation they all build on.
