According to a report by Caixin, the Hong Kong Securities and Futures Commission (SFC) conducted a surprise raid on the office of Huatai Financial Holdings (Hong Kong) this August, questioning employees about a suspected insider trading case involving U.S. stock options. Multiple sources familiar with the matter revealed that the investigation might be linked to an options trading incident from May this year: some investors were accused of trading related options in advance of Chinese regulators tightening oversight on cross-border brokerage businesses of Futu Holdings and Tiger Brokers, allegedly profiting over $100 million. Caixin previously reported that U.S. authorities have already filed a lawsuit regarding the case, disclosing that it involves over 310 accounts. https://(wublock123.com)/news/csrc-raids-huatai-financial-holdings-hong-kong-office-us-stock-options-insider-trading-67881
