Lee Kang Jyh

Lee Kang Jyh, chief executive officer of Photronics (PLAB), has been a consistent seller of company stock over the past year, with SEC Form 4 filings showing 38 total transactions and no open-market purchases. The aggregate value of his sales reached approximately $9.02 million, while his acquisition activity consisted entirely of option exercises and compensatory awards rather than cash purchases. The most recent cluster of activity, spanning January through April 2026, shows 18 separate sale transactions with values ranging from roughly $202,000 to $460,500, including sales on April 16, April 15, and April 13 worth $460,500, $451,000, and $225,000, respectively. The pattern reveals a steady cadence of selling rather than any concentrated liquidation event. Sales occurred at regular intervals—often multiple times per week—with values typically between $200,000 and $400,000. Interspersed with these sales were option exercises (coded "M") of approximately $43,000 to $53,750 each, which appear to be routine exercises that immediately preceded or coincided with the sale transactions. The absence of any "P" coded purchases, combined with the regularity of the "S" transactions, indicates a persistent net-selling bias over the observed period. The most recent filing on April 16, 2026, continued this trend, with no indication of a shift toward accumulation.
