How this page works
The chart holds 14 days of hourly values and updates every few minutes while the market is open, always on a delay of at least 15 minutes. The session status above comes from the exchange calendar in the site's data feed, so it reflects weekends and the market's actual trading hours.
The value shown is the market price of SPDR S&P 500 ETF Trust (SPY), an exchange-traded fund listed on NYSE Arca that tracks the S&P 500 index. It is the price of the fund, not the index level published by the index owner, so it can differ from the number quoted elsewhere.
