Mark L. Reuss, President of General Motors (GM), has demonstrated a clear pattern of insider selling activity over the past year, as evidenced by SEC Form 4 filings. Reuss has executed 24 trades, all involving GM stock, with a total sell value of $81.3 million and a total buy value of $21 million, reflecting a significant net selling bias. Notably, all 11 of his most recent transactions, spanning from September 2025 to February 2026, were sales, with no purchases recorded during this period. Among these recent sales, the largest transactions occurred on February 17, 2026, with three sales totaling $31.9 million, including a single transaction valued at $20.1 million. Smaller but notable sales were also recorded on October 22, 2025, amounting to $7.3 million, and September 25, 2025, totaling $8.2 million.
Reuss’s trading activity includes a mix of sales classified under codes "S" (sale), "M" (exercise of derivative security), and "F" (tax withholding). For instance, on February 7, 2026, he reported a tax withholding transaction valued at $13.7 million, while other sales appear to be outright dispositions of shares. The consistency and scale of these transactions suggest a deliberate reduction in his GM holdings over time. While insider sales can be driven by various factors, such as diversification or personal financial planning, the data underscores Reuss’s ongoing divestment from GM stock, with no recent indications of accumulation. This pattern aligns with his broader trading history, which has been predominantly characterized by selling activity.
