Hello,

I made beatthecouch.com in July and it's basically a game where you try to beat the S&P 500 and buy/sell when you want. Your opponent is a couch. It buys on day one and never sells.

Now over 100K+ games later, the hypothesis stands: it's not wise to try to trade and time the market. Here's the original data from the actual games itself.

Source: the game's own database, every completed game Jul 12 to Aug 28. Tool: Python and matplotlib. Market data: S&P 500 daily total returns 1928 to 2019.

thanks!

That's all well and good, but the experiment was done during a time unlike any other in market history with the idiotic growth levels that's been going on. Try it during most of the past 100 years when the market crashed for ran flat for years on end.
