China regulator watches closely as US probes insider trading tied to Futu, Tiger Brokers
China’s CSRC said it is closely monitoring a US insider-trading case filed by Susquehanna International Group, which alleges traders used material nonpublic information tied to China’s May 22 crackdown on offshore trading. Susquehanna says alleged profits exceeded $70m on put options in Futu Holdings and Up Fintech/Tiger Brokers; Citadel claims about $137m and seeks to join.
