Chongqing Beer only announced the research progress report on the therapeutic (synthetic peptide) hepatitis B vaccine. I felt that it was not a big benefit, and the main force used this to vigorously hype up the stock price. In addition to the small outflow on Thursday, there has been a large inflow of funds in the past week, which is suspected of pumping and selling, selling high and buying low. Through analysis, Chongbei is a market dominated by retail hot money, and the risk of intervention is very high.
