Core Viewpoint - The implementation of the new quantitative trading regulations on July 7 is not expected to significantly impact the market, as institutions have already prepared for these changes and conducted self-assessments prior to the regulations' release [4][7]. Group 1: Market Reactions and Rumors - There are rumors suggesting that the market drop on July 4 was due to the upcoming quantitative regulations, but institutions argue that the market had already anticipated these changes [2][4]. - A claim by a well-known economist that high-frequency trading frequency would drop from 299 times per second to 30 times is dismissed by multiple institutions as unfounded [3]. - The industry has noted a trend of blaming quantitative strategies for market issues, with calls to stop stigmatizing quantitative trading as synonymous with high-frequency trading [3]. Group 2: Details of the New Regulations - The "Procedural Trading Management Implementation Rules," or "quantitative regulations," will officially take effect on July 7, with prior public consultation having occurred in June 2024 [4]. - The regulations define high-frequency trading and allow exchanges to impose differentiated management requirements on investors engaging in such trading [6][9]. - Many leading institutions have already adjusted their trading frequencies to fall below the new high-frequency trading definitions [6]. Group 3: Impact on Quantitative Strategies - The extent of the impact from the new regulations will depend on the scale of individual products, with larger quantitative institutions potentially facing manageable effects [7]. - Most quantitative strategies are not expected to be significantly affected, as many products do not reach the thresholds set by the new regulations [7]. - The trend towards lower-frequency trading strategies is seen as a response to regulatory guidance and the limited capacity of high-frequency strategies to meet the demands of larger institutions [10][11]. Group 4: Future of Quantitative Trading - The shift towards lower-frequency strategies is viewed as a key trend for the future of quantitative trading in the A-share market, driven by the need for larger capacity and diverse strategies [10][11]. - Quantitative investment is recognized as a neutral tool that extends beyond high-frequency trading, with applications in risk management and value investment strategies [11].
