CG Oncology Inc (CGON)

Track

CG Oncology witnessed significant insider trading activity recently, characterized by heavy selling from officers and directors. While Brian Guan-Chyun Liu executed a substantial purchase, total divestments outweighed acquisitions. These movements followed the latest earnings report, occurring as the stock price trades near its fifty-two-week peak despite a recent quarterly performance miss.
