The Futu insider trading case has further developments. A U.S. court has ruled to freeze certain accounts on Interactive Brokers, Futu, and Tiger Brokers. The reason? Before the Chinese government launched a crackdown on cross-border brokers on May 22, mysterious funds made large short positions on Futu's stock. Market makers who suffered losses suspect that employees from Futu or Tiger may have leaked information in advance. Currently, at least 100 individuals are under investigation.
