Huang Jack Jiajia, chief executive officer of COE (ticker: COE), has been a consistent buyer of his company’s stock. His Form 4 filings show 128 total transactions, all in COE, with a total purchase value of $257.8 million and zero sales. The pattern is one-directional: open-market purchases only, with no sales, gifts, or tax-driven dispositions in the recent record.
The buying has been steady and substantial. Between July 23 and September 25, 2026, Jiajia executed 22 open-market purchases. The largest single transaction came on September 25, when he bought $14.1 million worth of COE shares. Other notable purchases include $10.3 million on September 23, $6.8 million on August 12, and $6.2 million on August 3. The smallest recent purchase was $22,080 on September 17. Two option exercises, on August 18 and October 1, carried a value of $0, meaning they were mechanical events with no cash outlay. One small tax-related withholding of $42,049 occurred on October 2.
The data shows no selling bias at all. Jiajia has not filed a single open-market sale, and the only non-purchase activity is the automatic withholding of shares to cover taxes (code F) and the zero-value option exercises. His buying is concentrated in the third quarter of 2026, with purchases spread across July, August, and September. The dollar values are not token gestures; they represent a sustained, large-scale accumulation of COE stock by its chief executive.
