What is an ETF? An ETF, or exchange-traded fund, is a bundle of securities such as stocks and bonds. Investors buy “units” (essentially shares) of ETFs that provide access to the performance of all the fund’s holdings, in exchange for a small annual fee that’s automatically taken out of the ETF’s returns. Exchange-traded funds are similar to mutual funds in that they’re pooled investments; however, ETFs trade on exchanges (just like stocks), so their prices change throughout the day; mutual fund prices do not. Why are ETF fees so important? ETF fees are taken out of the fund’s returns, so naturally the lower the fees, the more money the investor keeps. Fees are small – often measured in basis points (1/100th of a percent) – but can add up to big costs over time. Consider a $50,000 investment in a fund that charges 0.5% and returns 7% annually over 30 years will eventually generate $327,473 in returns. The same investment in a fund with similar performance but a 1% fee would generate $281,539 – that’s almost $46,000 lost to both fees and opportunity cost (the extra returns you would have generated had money spent on expenses been invested instead). How do I find the best cheap ETFs? Basic online ETF screeners can help you sort funds by cost, allowing you to find the absolute cheapest funds on the market. But not all cheap ETFs are good ETFs.
