The investment seeks investment results that track (before fees and expenses) the price and yield performance of its underlying index, the Nasdaq Chaikin Power US Small Cap Index. The fund invests at least 80% of the value of its assets (net assets plus the amount of any borrowings for investment purposes) in securities of small-capitalization U.S. issuers. The underlying index applies the Chaikin Power Gauge®, a quantitative multi-factor model that seeks to identify securities that are expected to outperform peers, to select securities from the Nasdaq US 1500 Index. The underlying index is an equally weighted index of small-capitalization securities.
