In a significant regulatory shift, the China Securities Regulatory Commission (CSRC) has implemented stringent measures aimed at stabilizing the Chinese stock market. These measures include prohibiting major institutional investors from selling equity holdings during the opening and closing 30 minutes of the trading day, where over 80% of shares trade hands, and banning short sales by certain accounts. Additionally, new quant funds, including one with assets under management worth tens of billions of yuan, are now required to disclose their investment strategies to regulators prior to commencing trading. This move, described as the government's most forceful attempt yet, seeks to support the nation's struggling $8.6 trillion stock market by reducing volatility and speculative trading. Critics, however, view these actions as a sign of desperation and a potential deterrent to foreign investment in China.
