The new regulations on quantitative trading officially came into effect on the 7th. The Detailed Rules for the Administration of Programmatic Trading, issued earlier by the Shanghai, Shenzhen, and Beijing Stock Exchanges, encompass comprehensive guidelines for report management, trading behavior, information system management, and high-frequency trading. The regulations emphasize enhanced supervision of high-frequency trading, clearly defining scenarios for identifying such trades, and introducing differentiated management requirements. Consequently, several quantitative trading institutions have adapted by tweaking their strategies and developing longer-term quantitative strategies to align with the new framework. Overall, these regulations are poised to induce structural diversity among quantitative strategies, accelerating the differentiation and consolidation of the industry landscape.
