Under typical circumstances, this exchange-traded fund (ETF) commits at least 80% of its total assets—which include both its net assets and any funds acquired through borrowing for investment—to a diverse array of equity securities. These investments target U.S.-based companies whose publicly traded market capitalizations align with the size spectrum of companies represented in the S&P 500 Index at the time of purchase. Furthermore, the fund may also allocate capital to other financial instruments that offer comparable economic exposure.
