In today’s Chart of the Day, we update a chart we have referenced often over the years. It shows the performance of the S&P 500 ETF (SPY) since it began trading in 1993 broken up by after-hours trading and intraday trading.  The after-hours strategy measures the performance of SPY had you brought the ETF at its closing price every day and sold it at the next trading day’s open.  The intraday strategy measures the performance of SPY had you bought the ETF at the open every day and sold it at the close that same day.

See whether the after-hours or intraday strategy has performed better by continuing this Chart of the Day by logging in (if you’re already a member) or starting a two-week free trial to any of our research membership levels.
