GM vs STLA: How General Motors Company and STLA Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: STLA is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. GM and STLA share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined GM and STLA exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

General Motors Company is a Detroit-based global automaker that designs, manufactures, and sells trucks, crossovers, cars, and automobile parts under the Chevrolet, GMC, Buick, and Cadillac brands, and provides automotive financing through its GM Financial arm. The overwhelming majority of its profit comes from North America, where full-size pickup trucks (the Chevrolet Silverado and GMC Sierra) and a broad lineup of crossovers and SUVs command strong pricing and margins. GM also operates through equity joint ventures in China, holds a portfolio of electric vehicles built on its Ultium battery platform, and had been developing autonomous-driving technology through Cruise before folding that effort into a leaner in-house driver-assistance program.

Stellantis N.V. is a multinational automaker created in 2021 from the merger of Fiat Chrysler Automobiles and France's PSA Group. It sells vehicles worldwide under roughly a dozen and a half brands, including the profitable US trio of Jeep, Ram, and Dodge, plus Chrysler, Peugeot, Citroen, Fiat, Opel, Vauxhall, Alfa Romeo, Maserati, and others. It is one of the largest carmakers in the world by volume and lists in the US, Milan, and Paris. After a strong early run on high North American profits, the company hit a rough patch marked by falling US sales, bloated inventory, strained dealer and supplier relationships, and a costly, aggressive electric-vehicle strategy.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• GM drivers: Truck and SUV profit engine plus capital return; EV rightsizing to cut losses.
• STLA drivers: Turnaround under a new CEO; Low valuation and capital returns.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: GM is deeply cyclical: new-vehicle demand, pricing, and margins can fall sharply in a recession or when interest rates raise the cost of auto loans. For STLA, the dominant risk is cyclicality: automakers' profits swing sharply with the economy, consumer confidence, and interest rates, so a downturn can quickly hurt sales and earnings.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick GM if you believe its drivers more; STLA if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the GM and STLA guides.

GM. GM's trailing P/E of roughly 31x is misleading because 2025 GAAP net income of about $2.7 billion was suppressed by more than $7.2 billion of one-time EV realignment charges; on a forward basis against 2026 adjusted EPS guidance of about $11.50 to $13.50, the multiple compresses to roughly 6x, one of the lowest among large-cap US companies. That gap reflects a market that treats GM as a deeply cyclical, tariff-exposed automaker rather than a growth compounder. Heavy buybacks (a new $6.0 billion authorization) and a raised dividend show management returning capital while the shares trade at a low earnings multiple.

STLA. Figures are approximate and tied to the asOf date; verify live numbers before acting. Automakers like Stellantis typically trade at low multiples because their earnings are cyclical and capital-intensive, so a cheap-looking valuation can reflect real risk rather than a bargain. The turnaround has shown early progress, but the stock's re-rating depends on sustained execution across North America, pricing, and EV strategy, not a single strong quarter.

Headline figures (approximate, JULY 2026): GM shows revenue (fy 2025) ~$185 billion, net income (fy 2025) ~$2.7 billion (after ~$7.2 billion of special charges), ebit-adjusted (fy 2025) ~$12.7 billion, 2026 ebit-adjusted guidance ~$13.5 billion to $15.5 billion (~$11.50 to $13.50 adjusted EPS); STLA shows business model Global automaker with roughly a dozen and a half brands including Jeep, Ram, Dodge, Peugeot, Citroen, Fiat, and Opel, recent results Q1 2026 sales up about 6% with a positive earnings beat; Q2 2026 shipments up roughly 10% year over year, turnaround New CEO Antonio Filosa calls 2026 the "year of execution," prioritizing US brands and affordable models, ev strategy Unwinding predecessor's aggressive all-electric plans, including a large charge tied to the change.

GM and STLA are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
