| Investment Objective: |
State Street SPDR S&P 400 Mid Cap Growth ETF seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of medium capitalization exchange traded U.S. equity securities exhibiting "growth" characteristics. In seeking to track the performance of the S&P MidCap 400 Growth Index, the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. In addition, in seeking to track the Index, the Fund may invest in equity securities that are not included in the Index. The Index measures the performance of the mid-capitalization growth segment of the U.S. equity market. The Index consists of those stocks in the S&P MidCap 400 Index exhibiting the strongest growth characteristics based on (i) sales growth (ii) changes in earnings over price and (iii) momentum. |
