Common questions
Is the General Motors CEO selling stock?
Yes. Mary Barra sold 1.02M shares ($87.0M) in the past 12 months, all of it under a trading plan disclosed in the filings.
Why are General Motors insiders selling?
Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 100% of sales by value ran under 10b5-1 trading plans disclosed in the filings. A trading plan schedules sales in advance.
Are any General Motors insiders buying?
No. Officers and directors reported no purchases in the past 12 months.
How much of their stake did General Motors insiders sell?
About 12% overall. As a group they ended with more shares than they started with. These figures leave out Mary Barra, the largest holder (most of their shares vested during the period, so a percentage would mislead). That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

17 of 17 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (17 exactly, 0 with a minor or footnoted difference). Percentages cover 3 of 17 officers and directors. Left out: Mary Barra, Mark Reuss, Grant Dixton, Christopher Hatto and Rory Harvey (most of their shares vested during the period, so a percentage would mislead); Patricia Russo and Wesley Bush (most holdings were last confirmed in 2022); Joseph Jimenez (most holdings were last confirmed in 2015); Devin Wenig and Judith Miscik (most holdings were last confirmed in 2019); Mark Tatum, Joanne Crevoiserat, Jon McNeill and Jan Tighe (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Sources and methodology1,329 filings from SEC EDGAR, and how we read them
All 1,329 Forms 3, 4 and 5 filed for General Motors (SEC CIK 1467858) from Jun 7, 2010 to Aug 3, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 5 filings were left out because General Motors filed them as an owner of another company's stock.
Probable 3-for-1 stock split on or before Nov 1, 2010 (split date stated in a footnote). Splits aren't reported as transactions; 2 holding lines changed by exactly this ratio, so earlier share counts are restated.
Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.
Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
