Common knowledge about stocks, what is the reason why retail investors avoid cutting stocks when investing in stocks in a bull market?

If you want to pay less tuition, bid farewell to losses, and make profits, there is a simple and practical way, which is to buy brokerage stocks. Brokerages are the biggest beneficiaries of the bull market, and brokerage stocks are natural bull stocks in the bull market. Buying brokerage stocks in a bull market does not have a high probability of making a profit, but it will definitely make a profit. The most important thing is to ignore the early gains of the market and continue to make profits along with the bull market. As long as you firmly believe that the stock market is a bull market, the market will continue to rise, and brokerage stocks will rise. Because a rising tide lifts all boats, and if the market rises, brokerage stocks will naturally rise. Veterans, do you still remember CITIC Securities from 2006 to 2007? In the bull market that year, the share price of CITIC Securities rose from 4.24 yuan to 117 yuan, an increase of 2,700 yuan, which is surprising!
