Core Viewpoint - The article discusses two main issues highlighted by Professor Liu Jipeng: the reduction of shareholding by major shareholders and quantitative trading, with a focus on the first issue. [1] Group 1: Advantages of Quantitative Trading - Quantitative trading has two notable advantages in the current market performance: it suppresses speculative trading on junk stocks through speed and is adept at identifying growth trends with greater precision. [1] - These advantages suggest that the A-share market may be moving away from a chaotic phase, aligning more closely with the development trajectory of Western stock markets. [1] Group 2: Human vs. Quantitative Strategies - In terms of short-term strategies and reaction speed, quantitative trading possesses unmatched advantages over human traders. [1] - However, for medium to long-term strategies, humans or hybrid approaches (combining human and algorithmic insights) currently demonstrate superior capabilities. [1] - Individual speculators lacking knowledge and long-term training are likely to incur losses, a trend that has been consistent over time and is independent of quantitative trading. [1]
