The Invesco S&P 500 Equal Weight Utilities ETF (RSPU) is structured to mirror the performance of the S&P 500 Equal Weight Utilities Plus Index. This fund commits a substantial portion—at least 90% of its overall assets—to investments in the securities that comprise its target index. The underlying index itself offers balanced exposure to the utilities sector by assigning identical weighting to the common stocks of all companies listed in the S&P 500 Index that fall under the utilities classification, as defined by the Global Industry Classification Standard (GICS). Both the ETF's holdings and the index's composition are adjusted through a rebalancing process every three months.
