Found this 2018 article, interesting/fun fact: The Stock Market Works by Day, but It Loves the Night
- If you had bought SPY at the last second of trading on each business day since 1993, and sold at the market open the next day — capturing all of the net after-hour gains — your cumulative price gain would be 571%
- On the other hand, if you had done the reverse, buying SPY at the first second of regular trading every morning at 9:30 a.m. and selling at the 4 p.m. close, you would be down 4.4%
