SPDR Portfolio Treasury ETF seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of Bloomberg U.S. Treasury Index that tracks the United States Treasury market. In seeking to track the performance of 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. The quantity of holdings in the fund will be based on a number of factors, including asset size of the fund.
