The investment seeks investment results that correspond generally to the price and yield (before the fund's fees and expenses) of an equity index called the NASDAQ AlphaDEXÂ Hong Kong Index. The fund normally invests at least 90% of its net assets (including investment borrowings) in the common stocks, depositary receipts, real estate investment trusts ("REITs") and preferred shares that comprise the index. The index is designed to select stocks from the NASDAQ Hong Kong Index (the "base index") that may generate positive alpha, or risk-adjusted returns, relative to traditional indices through the use of the AlphaDEXÂ selection methodology.
