Exchange-traded funds (ETFs) have become quite popular since their introduction back in the mid-1990s. ETFs are similar to mutual funds, but they trade throughout the day, on a stock exchange. In this way, they mirror the buy-and-sell behavior of stocks. This also means that their value can change drastically during the course of a trading day.
