Investors are gamblers and believe that they will be winners 10%. The more you lose, the more you throw money into the stock market, hoping to return the money and make money. After buying individual stocks, investors will not rationally use take profit and stop loss to control retracement, that is, when individual stocks fall, they can't bear to cut their meat, but add positions and get deeper.
In the market, some investors like to chase after the rise and kill the fall, that is, when the stock rises, they buy blindly for fear of missing the gains brought by the late rise of the stock, and when the stock falls, they sell blindly for fear that the stock will continue to fall, bringing greater losses, resulting in investors always losing money.
