Leveraged Exchange-Traded Funds (LETFs) are publicly-traded funds that promise to provide daily returns that are in a multiple (positive or negative) of the returns on an index. To meet that promise, the funds use leverage, which is typically obtained through derivatives such as futures contracts, forward contracts, and total-return swaps. As of the end of 2012, there were over 250 LETFs in North America with total assets of approximately $32.24 billion. While the amount of assets held by these funds is still small, their popularity continues to grow as their trading volume is significantly larger and much more dynamic than traditional, non-leveraged ETFs.
