By Cameron Huddleston, Former Online Editor August 20, 2009 Hey, have you heard about leveraged exchange-traded funds, one of the fastest growing ETFs? These funds let you double or triple the results of an index. But, wait, did you read the fine print? Those results are over the period of one day. If an index is up one day, you'll win big. But if it drops the next, you'll lose big. These funds are so volatile that ordinary investors should steer clear of them. In fact, the North American Securities Administrators Association named leveraged ETFs as one of this year's top ten investor traps.Investors in leveraged ETFs betting on market gains have lost 58% of their money since September 2006, according to TrimTabs Investment Research.
