Generally, our profits in the stock market depend on two major efforts, namely stock selection methods and operation methods.
The stock selection method determines the success rate of choosing rising stocks, and the operation method represents the extent to which you can profit after entering rising stocks and the extent to which you lose money by choosing falling stocks.
Strong stock selection ability means that the stocks you choose are all rising stocks, but some people are very capable of selecting stocks, but they can't make money because of their poor ability to operate. When choosing good stocks, they arbitrage too quickly, and when choosing bad stocks, they are slow to stop loss. As a result, profits earned several times have been eaten up by losses.
