Hoạt động quyền chọn put bất thường được ghi nhận trước thông báo xử phạt đối với FUTU và TIGR

The Huoxing Finance report states that, according to publicly available options data platforms and market information, prior to the China Securities Regulatory Commission's announcement on May 22 of its intention to impose administrative penalties on cross-border internet brokers such as Futu and Tiger Securities, abnormal spikes in trading volume of put options for Futu and Tiger were observed on May 7, 19, and 21. The highest trading volume occurred just before the official announcement; StreetInsider issued a warning at 09:57 Eastern Time on May 21 that FUTU and TIGR had experienced unusual put option trades. ThetaOwl data also showed that the Put/Call volume ratio for Futu options expiring on May 22 was significantly elevated on May 21. Some market participants believe these anomalies suggest that capital may have been positioned ahead of the announcement to short the stocks, raising concerns of “insider trading” or front-running.
