NAIL provides a way for investors to get 3x levered bullish exposure to Dow Jones U.S. Select Home Index. The index is market-cap weighted and includes firms in home construction, furnishings and fixtures, home improvement retailers as well as, producers, sellers and suppliers of building materials. It should be noted that NAIL is designed to be a trading vehicle, and not meant for long-term investment, so trading costs are more important than the fund's fee. As it rebalances its levered exposure daily, compounding and path dependency will skew its long-term returns relative to its underlying index.
