On December 26th, recently, the news about "hot money is quantified and accurately harvested" has been circulating in the market. One of the more representative views is that quantitative private equity has mastered the short-term operation methods commonly used in hot money through model training. Compared with hot money, quantitative funds are often more "fast and accurate" in the actual operation process. In addition, they have the advantage of short selling and short selling, so they can accurately harvest hot money. Recently, many market strong stocks will suddenly explode and fall after the daily limit, or some even strong stocks often fall directly or even drop by the limit the next day. Is quantitative really harvesting hot money as accurately as rumored? The operation of quantitative funds may indeed have a certain degree of impact on the stock price fluctuations of some hot money-operated stocks. Relevant hot money people believe that although quantitative is a part of the market, it constantly accelerates the pace of the market, blindly helping to rise and fall, which will actually have a greater negative impact on the ecology of the disk. After all, the ultra-fast order placement speed and super execution ability of quantitative are unmatched by people. However, a quantitative private equity investment director said that quantitative funds are an important part of the class A share market and also provide a certain amount of liquidity for the market. Generally speaking, quantitative funds hold hundreds or even thousands of individual stocks, and there is no situation of directional harvesting of hot money.
