In this post, we look at the performance of the overnight session when the S&P 500 opens at a 5-day low but at the same time, the close is higher than the open.
Overnight trading in the S&P 500 historically yields an average return of 0.04% from the close until the next day’s open, making it attractive for mean reversion strategies.
We backtest the following trading rules:
* SPY must open at a 5-day low.
* The close must be lower than the open.
* If 1 and 2 are true, then enter on the close.
* Exit tomorrow's close.
