Index funds track a market benchmark—like the S&P 500 or total stock market—by holding the same stocks or bonds in the same proportions. Instead of a manager picking individual investments, an index fund straightforward mirrors what's in its benchmark. This approach appeals to people who want broad market exposure without paying for active management, but questions come up about how they work, what they cost, and whether they fit different financial situations.
These articles answer the practical questions people ask: How do index funds differ from actively managed funds? What fees should you expect? Can you hold index funds in retirement accounts? What's the difference between an index fund and an index ETF? How do you choose between similar index funds? Whether you're considering your first investment or comparing options for a retirement account, these resources explain how index funds function and what to consider before investing.
