The reason many retail investors cannot make big money is that they have a problem with their mindset; they want to run away as soon as they make a little profit. Back in 2019, when I didn't have much money, I took on a bit of someone else's account to run CTA quant trading. As a result, there was a fool who manually closed the position. This led to a significant loss in potential profits. Since that time, I have developed a strong dislike for those self-righteous retail investors. I will never take on retail funds again. How should I put it? These people have no correct understanding; they do not have a fixed trading system. This time they made money from a trend and think trend trading is good, but the next time they lose on a trend, they consider switching to range trading. They are always thinking they can make money in every situation. Last year, I told a younger brother, 'First of all, do not take retail funds, especially those who think they know a lot, like those so-called market commanders. If you do take funds, make sure they are from women, as women tend to be more laid-back in their investments.'
