Keeping track of your ETF holdings is as easy as — you guessed it — keeping track of stocks. Every financial reporting service, from the Wall Street Journal to Reuters to the ETF sponsor, maintains current pricing and yield (for income ETFs) information for the ETFs on the market.

To track your ETFs, you'll need to know their trading symbols. Then all you have to do is look at a current price table, whether in the newspaper or online, to find out everything you need to know. Most ETF price tables contain data like closing price, the dollar and percent change from the previous trading day's closing price, and trading volume. Some also include the year-to-date price change, the day's high and low prices, and the annual high and low.
