What Is an ETF?
A basket of stocks in one investment
An ETF (Exchange-Traded Fund) holds a collection of stocks bundled into one investment you can buy like a single share. SPY, for example, tracks the S&P 500 — buying it gives you exposure to 500 companies at once. ETFs are a simple way to diversify without picking individual stocks.
