What the report says
North American Vehicle Transaction Signal
This report carries two verdicts, and both are Neutral. On the dealer lots, prices held: the average last listed price of a new GM vehicle was $54,314, up 1.2% from a year ago, and new vehicles sold in 72 days on average, three days faster than a year ago.
The weak spot is stock. GM dealers held 587,236 new vehicles in inventory on September 30, 17.6% more than three months earlier, a Market Days Supply of 94 days at the selling rate of the quarter's last 45 days, above GM's own normal range. The build sits mostly in full-size pickups and SUVs, ahead of the next-generation pickup launch in December.
Our count of new GM sales fell 11.7% from a year ago, but GM's own count fell 5.5%, and our share of GM's sales moved by six points between the two quarters, so we do not read the volume change as evidence either way.
The composite stays Neutral because GM Financial, software, warranty savings, regulatory credits and the shrinking electric-vehicle losses are outside our data and were all guided positively in July; a neutral composite is more likely to understate GM's quarter than overstate it.

What this report covers
MarketCheck data on new and used Chevrolet, GMC, Buick and Cadillac vehicles sold and listed at U.S. dealerships, July 1 through September 30, 2026. What we cannot see: GM's factory production and wholesale shipments to dealers, fleet sales that are not advertised at retail, sales outside the United States, GM Financial (guided to earn $2.5–3.0 billion before tax in 2026), OnStar and Super Cruise software revenue, warranty costs, regulatory credits, tariff costs, commodity and raw-material costs, electric-vehicle restructuring charges, GM International and China equity income. Those unseen pieces are well over a third of GM's expected 2026 operating profit, so the dealer-lot data alone cannot set the earnings direction. Our data measures retail sell-through; GM books revenue on wholesale shipments to dealers, and the two can move apart for a quarter or more. The earnings release can confirm the direction of this read, but GM does not disclose most of the U.S. dealer-level figures below. Treat this report as one tile in the investment mosaic.
