It’s easy to get confused about what the terms “mutual fund” and “index fund” refer to. The two terms refer to distinct categories: “mutual fund” refers to a fund’s structure, whereas “index fund” refers to a fund’s investment strategy. Many, but not all, index funds are structured as mutual funds, and many mutual funds are index funds. Generally speaking, though, “index fund” refers to a fund whose investments closely track a market index, while “mutual fund” refers to a broad class of investment funds that follow a range of investing strategies. It’s important to understand the similarities and differences between mutual funds and index funds so you can make an informed investing decision.
