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!

If you have some savings not investing them in some way means the real value of those savings will go down due to inflation. For Americans there’s also the risk that the USD will collapse in value since it’s overvalued at the moment and the whole “World Reserve Currency” thing won’t last forever and when it goes it will likely be a massive crash in the value of the USD.
That said, investing doesn’t mean it has to be in the Stock Market.
