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 Defined Emerging Markets Index. The fund normally invests at least 90% of its net assets plus the amount of any borrowings for investment purposes in stocks that comprise the index. The index is a modified equal-dollar weighted index designed by S&P to objectively identify and select stocks from the S&P Emerging Markets BMI Index that may generate positive alpha relative to traditional passive-style indices through the use of the AlphaDEX(R) selection methodology. The fund is non-diversified.
