董少鹏：一刀切停掉量化交易的想法完全错误

Core Viewpoint - The proposal to ban quantitative trading in the Chinese stock market has been met with skepticism, as it lacks sufficient justification and may not be the correct strategy for addressing market issues [2][11]. Group 1: Issues with Quantitative Trading - Quantitative trading is criticized for its speed and efficiency, which gives it an advantage over retail investors, leading to perceptions of unfairness [2][11]. - The notion that banning quantitative trading would benefit retail investors is flawed, as other entities like private equity and skilled traders also exploit high volatility [2][11]. - The true creators of high volatility are often large market players ("庄家") who manipulate stock prices, making retail investors mere followers [3][12]. Group 2: Market Impact and Statistics - During the peak of quantitative trading in 2023, it accounted for one-third of total market trading volume, which has led to confusion in trading signals and macroeconomic judgments [3][12]. - The high proportion of machine trading indicates a lack of trust among retail investors in the market, which is a significant concern that needs to be addressed from a political perspective [3][12]. Group 3: Recommendations for Regulation - Instead of an outright ban, regulations should be tailored to fit the characteristics of the Chinese stock market, such as requiring quantitative firms to disclose their top trading strategies quarterly [4][13]. - Additional measures could include imposing delays on trading orders, preventing order cancellations, and implementing cooling-off periods for stocks with significant price movements [4][13]. - It is suggested that quantitative trading should only be allowed for stocks with a market capitalization above a certain threshold, such as 10 billion or 50 billion yuan, to balance retail participation and institutional liquidity [4][14]. Group 4: Legal and Ethical Considerations - There should be strict legal measures against any manipulation of IPO prices and secondary market fluctuations, which are essential for protecting retail investors and ensuring fairness [5][14]. - The collaboration between quantitative traders and company insiders to exploit other shareholders' interests must be strictly prohibited, and existing laws need to be strengthened to combat fraudulent activities [5][14].
