CME Group stock gained a fresh insider-trading signal on November 2, when Chief Commercial Officer Julie Winkler sold 10,079 Class A shares. The transaction was disclosed in a Form 4 filing reviewed by StockTitan.
Winkler retains a direct stake
The filing lists a weighted-average sale price of USD 305.15, with executions ranging from USD 305.11 to USD 305.34. Winkler held 21,482 shares directly after the transaction, and the filing does not identify the sale as having been made under a Rule 10b5-1 plan.
The filing adds a new detail to the insider activity already covered in the previous report. Director Howard Siegel sold 2,000 shares on November 2 and retained 19,873 shares, while CME Group's October average daily volume reached a record 30 million contracts, according to the prior company activity report.
