Chao Xingjuan

Chao Xingjuan, President and CEO of CBLL, has filed 62 Form 4 transactions, all in a single company, with a total sell value of $11,569,808.63 and zero open-market purchases. The pattern is one-directional: she has sold shares consistently, with no buys recorded in the recent window. The recent activity, spanning May through September 2026, shows 14 open-market sales (code S) alongside option exercises (code M) that appear mechanical in nature. The largest single sale was $973,079.40 on September 2, 2026, followed by $786,317.45 on August 19 and $714,480 on August 3. Smaller sales include $521,775.38 on September 15, $468,724.60 on July 7, and $431,744.82 on June 8. The option exercises, such as $110,703.80 and $6,796.20 on multiple dates, are paired with same-day sales, a common pattern where shares are acquired and immediately liquidated. The sales are not clustered in a single burst. They occur at roughly monthly intervals from May 5 through September 15, 2026, with values ranging from $28,775.40 to nearly $1 million. The total recent sell value across these 14 transactions is approximately $5.6 million. There are no grants (code A), gifts (code G), or conversions (code C) in the recent data, and no purchases of any kind. The direction is unambiguous: Chao has been a net seller of CBLL stock throughout the period, with the selling bias consistent and sustained.
