Educational explanation
An exchange-traded fund, or ETF, is a pooled investment that can hold hundreds or thousands of stocks, bonds, or other assets. They trade on markets like stocks, which makes them accessible and easy to understand for educational purposes. ETFs can simplify diversification, but they still carry risk and should be studied carefully.
Example
Instead of buying one company stock, an investor may hold an ETF that includes a broad range of companies. This can spread exposure across many businesses, though it still depends on the chosen market or strategy.
