Xie Michael

Xie Michael, VP of Engineering & CTO at Fortinet (FTNT), has demonstrated a clear selling bias in recent insider transactions, with no open-market purchases recorded in the available data. According to SEC Form 4 filings, Xie has executed 29 trades exclusively in FTNT stock, totaling $5.48 million in buys—likely from option exercises or awards—and $77.36 million in sales. The most significant disposals occurred in concentrated batches, including three sales on February 2, 2026, worth $16.68 million, $10.48 million, and $777,246, followed by a $5.48 million transaction coded as derivative-based (M). Earlier activity shows a similar pattern, with three sales on August 4, 2025, amounting to $38.12 million, $7.45 million, and $1.37 million, as well as smaller November 2025 disposals totaling $306,825. The absence of recent buying activity and the repeated liquidation of large FTNT positions suggest a sustained reduction in Xie’s stake. While some transactions, such as the February 2026 sales, coincided with derivative-related activity (coded M), the overwhelming majority represent outright disposals (coded S). The scale of these sales—particularly the multi-million-dollar transactions in August 2025 and February 2026—indicates a deliberate unwinding of holdings rather than routine diversification. With all activity focused on FTNT, Xie’s trading history reflects a single-company concentration now being systematically pared down.
