Stock ETFs: The Foundation of Equity Investing
Stock ETFs, also known as equity ETFs, are among the most popular types, focusing on stocks from various companies. They track market indices, sectors, or specific groups of stocks, providing exposure to the equity markets without the need to pick individual shares.

For instance, imagine a stock ETF as a diversified fruit basket—containing apples, oranges, and bananas—instead of betting on just one fruit. This setup allows investors to gain from overall market growth.
