Some asset classes gravitate toward high fees, and some assets are geared toward low fees. Indexed products—such as exchange-traded funds (ETFs) and index mutual funds—usually carry relatively low fees and are a good choice for value-conscious investors. There are often alternatives (e.g., multiple S&P 500 index funds) available from several providers to evaluate. Keep an eye on the fees that your investments charge, since those fees will take a bite out of your savings over time.
