The investment seeks to provide investment results that closely correspond, before expenses, to the performance of the Nasdaq US Mega Cap Select Leaders Index (the index). Under normal circumstances, the fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities that compose the index at the time of purchase. The index uses a quantitative model designed to identify equity securities of companies in the Nasdaq US 500 Large Cap Index (the parent index) that have the largest market capitalizations, with higher weights given to less volatile securities.
