The State Street SPDR S&P Aerospace & Defense ETF (XAR) is designed to mirror the total return performance of the S&P Aerospace & Defense Select Industry Index, prior to deducting fees and expenses. This fund provides specific access to the Aerospace & Defense segment, featuring companies identified within this sector by the S&P Total Market Index. Utilizing a modified equal-weighting approach, the ETF strives to offer diversified, less concentrated exposure across large, mid, and small-capitalization stocks within the industry.
