General Motors Co. (NYSE:GM)

An analysis of the common stock valuation ratios reveals a distinct two-phase trend: a period of valuation contraction between early 2022 and mid-2024, followed by a sharp expansion in multiples through early 2026.

Price to Earnings (P/E) and Price to Operating Profit (P/OP)

Both ratios exhibited a high degree of correlation, characterized by a steady decline from March 2022, reaching trough levels in September 2023, where the P/E stood at 3.94 and the P/OP at 3.56. After remaining suppressed through the first half of 2024, a significant upward trajectory began in late 2024. This escalation accelerated aggressively during the latter half of 2025, with the P/E ratio rising from 7.13 in June 2025 to 29.26 by March 2026, and the P/OP ratio increasing from 4.37 to 28.67 over the same period.

Price to Sales (P/S)

The P/S ratio demonstrated relative stability compared to earnings-based multiples. A downward trend is observed from 0.48 in March 2022 to a low of 0.25 in September 2023. While the ratio fluctuated between 0.25 and 0.35 throughout 2024, a gradual increase occurred toward the end of the period, peaking at 0.46 in December 2025 before concluding at 0.43 in March 2026.

Price to Book Value (P/BV)

The P/BV ratio remained below 1.0 for the majority of the analyzed period, indicating the stock traded at a discount to its book value. The minimum value of 0.53 was recorded in September 2023. A trend reversal is evident in late 2025, with the ratio surpassing the 1.0 threshold to reach 1.28 in December 2025, before settling at 1.14 in March 2026.

The divergence between the relatively stable sales-based multiples and the exponentially increasing earnings-based multiples suggests that the valuation surge in late 2025 and early 2026 is driven by a significant shift in earnings expectations or a contraction in earnings relative to the share price, rather than a commensurate increase in revenue.

The financial trajectory from March 2022 through March 2026 reflects a significant divergence between market valuation and fundamental earnings performance. Initially characterized by stability and low valuation multiples, the period concludes with a sharp expansion in the price-to-earnings ratio driven by rising share prices and declining earnings per share.

Share Price Performance

The share price remained relatively range-bound between US$33.34 and US$39.32 throughout 2022. Following a dip to US$28.56 in September 2023, a sustained upward trend emerged in 2024, with prices exceeding US$50 by late 2024. A period of rapid acceleration occurred in 2025, peaking at US$86.38 in December 2025 before a moderate correction to US$78.95 in March 2026.

Earnings Per Share (EPS) Trends

Earnings exhibited an initial growth phase, rising from US$6.07 in March 2022 to a peak of US$10.00 in September 2024. However, a precipitous decline followed, with EPS dropping to US$7.23 by December 2024 and continuing a consistent downward trajectory through March 2026, where it reached a period low of US$2.70.

Price-to-Earnings (P/E) Ratio Evolution

The P/E ratio remained compressed between 3.94 and 6.37 from March 2022 through December 2024, indicating a conservative market valuation relative to earnings. Beginning in 2025, the ratio expanded exponentially, rising from 7.13 in June 2025 to 29.26 by March 2026. This surge is the result of a mathematical inverse relationship where the market price increased while the underlying earnings contracted, signaling a fundamental shift in the valuation multiple.

An analysis of the valuation metrics from March 2022 through March 2026 reveals a significant shift in the relationship between market pricing and operating performance. For the majority of the period, valuation remained conservative, but a sharp divergence emerged in the latter stages of the observation window.

Share Price Evolution

The share price exhibited moderate volatility between 2022 and 2024, generally fluctuating between $28.56 and $53.73. A strong upward trajectory began in the second half of 2024, with the price accelerating through 2025 to reach a peak of $86.38 in December 2025, before settling at $78.95 by March 2026.

Operating Profit per Share Trends

Operating profit per share demonstrated a consistent growth trend from March 2022 ($5.65), reaching a peak of $12.90 in March 2025. This period of expansion was followed by a precipitous decline starting in mid-2025, with profits falling sharply to $3.22 by September 2025 and further contracting to $2.75 by March 2026.

Price to Operating Profit (P/OP) Ratio Dynamics

The P/OP ratio remained suppressed for the first three years, trading within a range of 3.49 to 6.84, suggesting that the stock was priced conservatively relative to its operating earnings. A dramatic pivot occurred starting in September 2025, as the ratio climbed from 7.69 to a peak of 28.67 by March 2026. This exponential increase in the multiple is driven by the combination of rising share prices and a simultaneous severe contraction in operating profit per share, indicating a significant expansion in the valuation multiple relative to fundamental operating performance.

An analysis of the valuation metrics reveals a period of significant divergence between revenue growth and market valuation, followed by a corrective alignment in the latter stages of the observed period.

Sales per Share Trend

A consistent and strong upward trajectory in sales per share is observed, rising from 80.48 US$ in March 2022 to 185.72 US$ by March 2026. This represents a steady expansion of revenue generation relative to the outstanding share count throughout the entire duration of the analysis.

Price to Sales (P/S) Ratio Volatility

The P/S ratio exhibited a general downward trend during the first half of the period, decreasing from a high of 0.48 in March 2022 to a low of 0.25 in September 2023. Despite the continuous growth in sales per share, the ratio remained depressed between 0.25 and 0.35 through March 2025, indicating that the market valuation did not keep pace with the company's revenue growth.

Valuation Recovery and Convergence

A notable shift occurred between June 2025 and December 2025, where the P/S ratio climbed from 0.27 to 0.46. This spike was primarily driven by a rapid increase in share price, which rose from 48.89 US$ to 86.38 US$ during that window, while sales per share growth began to plateau. By March 2026, the P/S ratio settled at 0.43, returning toward the valuation levels seen at the start of the period.

Overall, the data indicates that for a significant duration, the market undervalued the company's revenue growth, as evidenced by the declining P/S ratio amidst rising sales. The subsequent increase in the ratio suggests a market re-evaluation or a shift in investor sentiment that aligned the share price more closely with the expanded revenue base.

The analysis of valuation metrics reveals a transition from a period of significant discounting relative to book value to a period of premium valuation. Throughout the observed timeframe, a divergence is evident between the steady growth of book value and the more volatile movements of the share price.

Book Value per Share (BVPS) Trends

A consistent upward trajectory in book value per share is observed from March 2022 ($42.59) through June 2025 ($71.15). This steady growth indicates a persistent increase in the accounting value of equity per share. A brief contraction occurred in December 2025, with the value dipping to $67.61, followed by a recovery to $69.49 by March 2026.

Share Price Volatility and Growth

The share price exhibited significant fluctuations, characterized by a period of instability between 2022 and early 2023, reaching a period low of $28.56 in September 2023. A strong recovery phase followed throughout 2024 and 2025, resulting in a peak of $86.38 in December 2025 before a moderate correction to $78.95 in March 2026.

Price to Book Value (P/BV) Ratio Interpretation

For the majority of the analyzed period, the P/BV ratio remained below 1.0, signaling that the market valued the company at a discount to its book value. This discounting reached its maximum in September 2023 with a ratio of 0.53. A fundamental shift in valuation occurred in the latter half of 2025, as the ratio crossed the 1.0 threshold, peaking at 1.28 in December 2025. This indicates a transition from a value-discounted state to a premium valuation, reflecting increased market confidence or higher expectations of future returns relative to the company's asset base.
