Reiss Joel, Co-Chief Operating Officer at TransDigm Group (TDG), has demonstrated a pronounced selling bias in recent insider transactions, with no recorded purchases in the latest filings. Over his tenure, Joel has executed 152 trades exclusively in TDG, with total sales exceeding $40.2 million against $8.9 million in buys—a nearly 4.5-to-1 ratio favoring disposals. The most recent activity, concentrated on March 16, 2026, saw 19 separate sales totaling approximately $4.6 million, ranging from $24,457 to $662,199, alongside a single $1.1 million acquisition marked as a market purchase (code "M"). Earlier in February 2026, five additional sales occurred, including a $429,299 transaction. The pattern suggests systematic divestment, with no buys since at least early 2026. While the sales could represent routine portfolio management—particularly given their staggered sizes—the absence of offsetting purchases in the same period indicates a directional reduction in exposure to TDG. The transactions occurred at varying price points, with no single dominant trade dominating the activity. As an executive with deep ties to the aerospace supplier, Joel’s trading history reflects a long-term relationship with the company, though recent filings show a clear shift toward liquidation.
