Chinese Stock Exchanges Consider Suspending Data Services to Quant Funds, Sources Say

Chinese stock exchanges, including the Shanghai and Shenzhen bourses, are considering suspending certain value-added market data services to quantitative (quant) funds, sources say. This move could involve withholding granular transaction details, such as tick-by-tick data, which are crucial for high-frequency trading (HFT) strategies employed by these funds. The decision comes amid a broader crackdown on hedge funds and market manipulation in China, following lessons learned from the 2014-15 market bubble. The potential suspension of these data services is part of China's efforts to mitigate social damages and market volatility, Bloomberg reports.
