ETF Guide: Everything You Need to Know
March 14, 2026
What are ETFs?
ETF (Exchange-Traded Fund) is a fund that replicates an index and trades on the exchange like a stock.
Example: SPY replicates the S&P 500. By buying 1 share, you're investing in the ~500 largest US companies at once.
Main ETFs: - Brazil: BOVA11 (Ibovespa), IVVB11 (S&P 500 in BRL), HASH11 (Crypto) - USA: VOO/SPY (S&P 500), VTI (Total Market), QQQ (NASDAQ)
PaxMoney tracks all these ETFs with automatically updated quotes.
Advantages of ETFs
Instant diversification: One share = dozens or hundreds of assets
Low cost: Management fees usually below 0.5%/year
Liquidity: Buy and sell anytime during market hours
Simplicity: No need to pick individual stocks
Transparency: Fund composition is public
For beginners, starting with ETFs is probably the best investment decision possible.
