Core Viewpoint - The new regulations significantly impact high-frequency trading strategies, leading to a systematic compression of their survival space in the market [1][4]. Group 1: Regulatory Changes - The implementation of the "Procedural Trading Management Implementation Rules" marks the beginning of a strong regulatory era for algorithmic trading in China's capital markets [2]. - The new rules define high-frequency trading as submitting or withdrawing orders exceeding 300 times per second or 20,000 times per day, imposing differentiated fees for exceeding these thresholds [6][7]. - The regulations also outline four types of abnormal trading behaviors, although specific standards for triggering these behaviors have not been clearly defined [7]. Group 2: Impact on Trading Strategies - Many private equity firms have already begun modifying their trading algorithms in response to the new regulations, with one firm reducing its order submission rate from 400 to 30 per second, resulting in a potential annualized return loss of 0.8% for each frequency reduction [3][4]. - The new rules have led to a general increase in costs for day trading strategies among small and medium-sized quantitative private equity firms, with costs rising by approximately 30% [15]. - Some firms are developing new strategies that incorporate macroeconomic factors, such as low-frequency CTA strategies, which have shown a potential 40% reduction in annualized volatility during backtesting [16]. Group 3: Industry Transformation - The new regulations are expected to reshape the industry ecosystem, with high-frequency strategies being less prevalent in overall quantitative AUM but serving as a critical survival tool for smaller private equity firms [14][13]. - The tightening of regulations is anticipated to accelerate the process of industry consolidation, compelling managers to strengthen their competitive advantages [19]. - The future of the quantitative industry will likely see a shift towards more refined competition, focusing on client service capabilities, product design, and post-investment returns [18].
