| Investment Objective: |
State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks a broad universe of exchange traded U.S. equity securities. In seeking to track the performance of the S&P Composite 1500 Index (the "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. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The Index is designed to measure the performance of the broad exchange-traded U.S. equity securities universe. The Index consists of those stocks included in the S&P 500 Index, the S&P MidCap 400 Index, and the S&P SmallCap 600 Index. Each underlying index includes U.S. common equities listed on the NYSE, NYSE Arca, NYSE American, NASDAQ Global Select Market, NASDAQ Global Market, NASDAQ Capital Market, Cboe BZX, Cboe BYX, Cboe EDGA, or Cboe EDGX that meet specific market capitalization requirements. |
