Mary T. Barra, Chair and CEO of General Motors, has been a consistent seller of GM stock over the past year, with Form 4 filings showing 59 total transactions across two companies. The overwhelming majority of her activity involves open-market sales of GM shares, totaling approximately $193.3 million in sell value, while her only acquisitions—about $635,700 in value—came from compensation awards and option exercises rather than open-market purchases. The pattern is unambiguous: Barra has not made a single open-market purchase during this period, and her recent activity shows 14 sales in the most recent reporting window alone. The most concentrated selling occurred in late July 2026, when Barra executed multiple large GM transactions on July 27 and July 28. On July 28 alone, she sold shares worth roughly $9.8 million, $4.4 million, $6.3 million, and $8.3 million, paired with option exercises valued at $2.5 million, $3.4 million, and $3.8 million—a classic exercise-and-sell pattern that converts vested options into cash. The prior day saw additional sales of $4.7 million and $4.2 million alongside a $2.6 million option exercise. Earlier in the summer, she sold $7.1 million and $757,000 worth of GM stock on June 16, and $1.7 million on June 9, with corresponding option exercises in each case. Her May activity was similarly heavy, including sales of $8.5 million on May 27 and combined sales of roughly $11.5 million on May 28. The only non-GM transaction in the recent filings was a June 30, 2026 award of Disney (DIS) stock worth approximately $102,000, which reflects her role on that company’s board rather than an investment decision. Across all filings, Barra’s selling is systematic and recurring, with no buying bias whatsoever—every open-market transaction is a sale, and the dollar figures are substantial, often exceeding $5 million per day. While option exercises and tax-related withholdings are mechanical, the sheer volume of outright sales—north of $190 million—signals a sustained distribution of GM equity, with the most recent cluster in late July showing no sign of slowing.
