Most professional investors aren’t either. Something like 70% of professionally managed funds fail to beat their index over a 10 year period, and the number goes down from there. And these aren’t idiots, they have a lot of education and professional experience, yet they still fail.
If timing the market worked consistently, everyone would do it. And if everyone did it, that means nobody times the market (stocks go up and down based on supply and demand, not some magic, hidden force). It’s highly unlikely that any individual will consistently win by trying to time the market.
