About the ETF

SPY was created on 1993-01-22 by SPDR. The fund's investment portfolio concentrates primarily on large cap equity. The ETF currently has 652780.63m in AUM and 504 holdings. SPY tracks a market cap-weighted index of US large- and mid-cap stocks selected by the S&P Committee.

SPY is one of the largest and most heavily-traded ETFs in the world, offering exposure to one of the most well known equity benchmarks. While SPY certainly may have appeal to investors seeking to build a long-term portfolio and include large cap U.S. stocks, this fund has become extremely popular with more active traders as a way to toggle between risky and safe assets.
