GM risk-adjusted returns: Sharpe, Sortino and volatility

Over 5 years, GM had a Sharpe ratio of 0.31 against 0.67 for the S&P 500, so it earned less return per unit of risk than the index. Its annualized volatility was 33.6% and its beta 1.40: it tended to move about 1.4× as much as the market.

MetricGMS&P 500
Annual return+8.7%+13.7%

Sharpe ratio0.310.67
Sortino ratio0.471.08
Max drawdown (month-end)−51.3%−23.9%

Sharpe divides return above cash by total volatility; Sortino counts only downside volatility. Both use monthly returns and the 1–3 month T‑bill ETF (BIL) as the risk‑free rate.

How GM behaved in past crashes

GM’s deepest fall in the crises below was −53.0% in the 2022 inflation bear market, against −25.4% for the S&P 500. The last column turns that into money: what a $100,000 position would have lost from peak to trough.

What moves with GM, and what doesn’t

Correlation runs from −1 (moves opposite) to +1 (moves in lockstep). Over the last 60 months of monthly returns, GM’s correlation with the S&P 500 was 0.65, with the Nasdaq‑100 0.53, with long Treasuries (TLT) 0.33 and with gold (GLD) 0.04.

Adding a 5% GM position to an S&P 500 portfolio would have moved its 5‑year volatility from 15.7% to 16.0%.

Where GM’s revenue comes from

In fiscal 2025 (the year to Dec 31, 2025), GM’s largest reported region was the United States, with 82.2% of its $168.0 billion revenue. By region: United States 82.2%; Non-US 17.8%.

By business, the largest segment was GMNA, with 83.5% of $184.8 billion revenue (−2.0% on the year before).

GM financial health scores

In Exent’s Oct 20, 2026 snapshot, GM’s Altman Z‑score was 1.19, in the distress zone (where 180 of the 794 non‑financial US stocks Exent tracks sit). Its Piotroski F‑score was 7 out of 9; 40% of scored stocks reach 7 or more.

The Altman Z‑score combines five balance‑sheet and earnings ratios into one bankruptcy‑risk score: below 1.81 is the distress zone, 1.81–2.99 grey, above 2.99 safe. It is not meaningful for banks, insurers and REITs. The Piotroski F‑score counts nine yes/no tests of profitability, leverage and efficiency; 8–9 is strong, 0–2 weak. Both come from the latest annual statements. Which stocks have the highest bankruptcy risk?

How much is GM’s CEO paid?

Mary T. Barra, GM’s Chair and Chief Executive Officer, received total pay of $29.9 million for fiscal 2025, up 1.4% from $29.5 million for fiscal 2024, according to the company’s proxy statement filed with the SEC on Apr 20, 2026. 72% of it came as stock and option awards, valued when they were granted rather than when they pay out. The median CEO pay across the 378 S&P 500 companies Exent tracks was $17.2 million, so GM’s CEO earned 1.7 times as much.

Does GM get federal contracts?

In federal fiscal year 2026 (October 1, 2025 to September 30, 2026), US government agencies obligated $662.4 million in contracts to General Motors Company and its units, according to USAspending.gov, up 10.0% from $602.4 million the year before.

Contract obligations are what agencies committed in the year, not cash paid; every subsidiary and unit USAspending.gov lists under the parent company is rolled up into one total. Which companies get the most federal contracts?

The right benchmark for GM

Exent matches every holding to the index with the most similar risk. For GM that is SPY (the S&P 500). Comparing a holding with an index that carries very different risk makes good results look bad and risky ones look clever. Read why the S&P 500 is the wrong benchmark for most portfolios.

Data and methodology

Returns are total returns from month‑end adjusted closing prices (dividends reinvested) through Sep 30, 2026. Crisis drawdowns and trailing maximum drawdowns use daily prices. Analyst coverage counts ratings published in the last 12 months, shown with a 30‑day delay. Full method: Exent methodology.

Company data as of Oct 20, 2026. The move around an earnings report runs from the close before it to the close after it; a price target counts as hit when the stock closed at or beyond it within 12 months (Exent analyst data). Revenue by region and segment, share counts and executive pay come from company filings; insider trades from SEC Form 4, short interest from FINRA, institutional ownership from 13F filings, Congress trades from STOCK Act disclosures filed with the House and Senate, federal contracts from USAspending.gov. Filings from the last 30 days are shown as counts only.
