▶ Watch the ShortWhat it taught me
Since 1993, $100 in the S&P 500 fund SPY held only overnight became about $1,400, and held only during market hours it became about $130.
This is a backtest on SPY’s daily open and close prices, price only with no costs, and the exact split depends on which opening price is used. Since 2001 the gap is a lot smaller, and it’s a measurement, not a plan.
