SPY · State Street® SPDR® S&P 500® ETF Trust

Fund background

SPY is the State Street SPDR S&P 500 ETF Trust, an exchange-traded unit investment trust. State Street Global Advisors Trust Company serves as trustee. Its shares trade on NYSE Arca in US dollars.

The fund aims to follow the S&P 500 Index's price and dividend performance before expenses. That benchmark covers large US companies and weights them by market capitalization adjusted for shares available to public investors.

SPY's market price can differ from its net asset value. Fund expenses and brokerage costs reduce investor returns, and exposure to the equity market includes the risk of loss.
