International Business Machines Corp. (NYSE:IBM)

The valuation ratios exhibit a period of significant volatility followed by a phase of expansion and a subsequent return toward historical norms. A notable divergence is observed between net income-based valuation and operating profit-based valuation during the 2022-2023 period, suggesting the impact of non-operating items on bottom-line earnings.

Price to Earnings (P/E) Ratio

Extreme volatility is observed between September 2022 and June 2023, with the ratio peaking at 95.23. This spike indicates a temporary compression of net earnings relative to the stock price. Following a return to a baseline of approximately 18-22 in 2024, a second expansion occurred, peaking at 41.60 in June 2025, before contracting to 18.15 by June 2026.

Price to Operating Profit (P/OP) Ratio

The P/OP ratio remained comparatively stable during the period of P/E volatility, maintaining a range between 13.98 and 15.37 from March 2022 to September 2023. A gradual upward trend followed, reaching a peak of 25.48 in December 2024, which suggests a period of higher valuation multiples relative to core operating performance, before moderating to 16.30 by June 2026.

Price to Sales (P/S) Ratio

A consistent baseline between 1.89 and 2.16 was maintained through the first several quarters of the analysis. Starting in December 2023, a sustained expansion is evident, with the ratio climbing to a peak of 4.07 in September 2025. This indicates a significant increase in the market's valuation of each dollar of revenue, followed by a correction toward 2.82 by June 2026.

Price to Book Value (P/BV) Ratio

The P/BV ratio followed a trajectory similar to the P/S ratio, moving from a low of 5.29 in March 2023 to a peak of 9.55 in September 2025. This upward trend reflects an increasing premium attributed to the company's equity over its book value, which subsequently declined to 5.65 by the end of the period.

Overall, the valuation metrics indicate a cyclical pattern of expansion peaking in mid-to-late 2025 across all primary ratios. The synchronization of the P/S, P/OP, and P/BV peaks suggests a broader market re-rating of the company during this window, while the subsequent decline across all metrics by June 2026 points toward a valuation normalization.

The valuation trajectory from March 2022 through June 2026 is characterized by three distinct phases: a period of extreme volatility driven by earnings compression, a subsequent expansion of the valuation multiple, and a final return to historical baseline levels.

Valuation Volatility and Earnings Compression

Between September 2022 and June 2023, the Price-to-Earnings (P/E) ratio experienced a sharp increase, peaking at 95.23. This spike was not driven by a surge in share price, which remained relatively stable during this window, but was instead the result of a significant contraction in Earnings per Share (EPS), which fell from 6.19 in June 2022 to 1.40 in September 2022. This period reflects a temporary decoupling of price and earnings, leading to an inflated valuation multiple.

Multiple Expansion and Market Optimism

Following a normalization in late 2023, the P/E ratio entered an expansionary phase starting in early 2024. The ratio climbed from 18.66 in March 2024 to a peak of 41.60 by June 2025. During this interval, the share price grew more rapidly than the underlying earnings, with the price ascending from 166.20 to 260.51. This trend suggests a period of increased investor confidence or expectations of future growth that exceeded the immediate EPS gains.

Convergence and Normalization

From September 2025 through June 2026, a trend of valuation normalization is observed. The P/E ratio declined from 33.69 to 18.15. This compression occurred as the share price corrected downward from its peak of 285.00 while Earnings per Share remained robust, stabilizing between 11.38 and 11.44. By the end of the observed period, the valuation multiple returned to a range consistent with the levels seen in early 2022, indicating a realignment of the share price with actual earnings performance.

The financial analysis of the valuation metrics from March 2022 through June 2026 reveals a period of significant volatility in market pricing contrasted with a steady, upward trajectory in operational profitability. The Price to Operating Profit (P/OP) ratio underwent a full cycle of contraction, aggressive expansion, and subsequent normalization.

Share Price Trends

The share price experienced three distinct phases. An initial period of relative stability and slight decline occurred between March 2022 and March 2023, with values fluctuating between 136.19 and 125.89. This was followed by a strong bullish trend that peaked at 285.00 in September 2025. The final phase was characterized by a corrective downturn, with the price receding to 206.65 by June 2026.

Operating Profit Performance

Operating profit per share demonstrated consistent growth over the analyzed period. Starting at 7.98 in March 2022, the figure rose steadily to reach a peak of 13.02 in March 2026. This persistent increase indicates a strengthening of core business operations and improved efficiency per share, independent of the fluctuations seen in the market share price.

P/OP Ratio Interpretation

The P/OP ratio serves as a primary indicator of market sentiment relative to operational earnings. The ratio initially compressed from 17.07 to a low of 13.98 by March 2023, suggesting a period of undervaluation or cautious investor sentiment. A sharp expansion occurred between June 2023 and December 2024, where the ratio reached a peak of 25.48. This peak was driven by share price appreciation that significantly outpaced the growth in operating profit. From December 2024 through June 2026, the ratio contracted back to 16.30. This contraction was the result of declining share prices occurring simultaneously with record-high operating profits, indicating a reversion toward historical valuation norms.

The Price to Sales (P/S) ratio exhibits a distinct three-phase cycle consisting of initial stability, a period of significant expansion, and a subsequent correction. From March 2022 through March 2023, the ratio remained relatively stagnant, fluctuating within a narrow band between 1.89 and 2.10. A sharp upward trend emerged starting in June 2023, culminating in a peak ratio of 4.07 by September 2025. This was followed by a valuation contraction, with the ratio declining to 2.82 by June 2026.

Drivers of Valuation Fluctuations

The volatility observed in the P/S ratio is primarily attributed to fluctuations in the share price rather than changes in revenue. The share price experienced substantial growth and volatility, rising from 136.19 in March 2022 to a peak of 285.00 in September 2025. Because the P/S ratio tracks these price movements closely, it is evident that the expansion in the multiple was driven by market pricing dynamics.

Revenue Performance Trends

Sales per share demonstrated a consistent and gradual increase throughout the analyzed timeframe. Starting at 64.89 in March 2022, sales per share grew steadily to 73.34 by June 2026. This linear growth indicates a stable operational trajectory, suggesting that the dramatic spikes in the P/S ratio were a result of multiple expansion rather than an acceleration in fundamental sales growth.

Analysis of Multiple Expansion and Contraction

A significant valuation re-rating occurred between December 2023 and September 2025, during which the P/S ratio climbed from 2.73 to 4.07. This period represents a substantial increase in the premium the market was willing to pay per dollar of sales. The subsequent decline from September 2025 to June 2026 indicates a corrective phase, although the ending ratio of 2.82 remains elevated compared to the baseline levels established in 2022.

The Price to Book Value (P/BV) ratio exhibits a cyclical pattern over the analyzed period, characterized by an initial phase of compression, a period of significant expansion, and a subsequent contraction. While the book value per share demonstrated consistent growth, the volatility of the share price acted as the primary driver for the fluctuations in the P/BV ratio.

Book Value Per Share (BVPS) Trend

A steady upward trajectory is observed in the book value per share, rising from 21.18 US$ in March 2022 to 36.57 US$ by June 2026. This consistent growth indicates a systematic increase in the company's net asset value per share over the observed timeframe.

Share Price Volatility

The share price experienced notable fluctuations, starting at 136.19 US$ in March 2022 and reaching a peak of 285.00 US$ in September 2025. A significant rally occurred between December 2023 and September 2025, followed by a correction that brought the price down to 206.65 US$ by June 2026.

P/BV Ratio Analysis

The P/BV ratio initially declined from 6.43 in March 2022 to a low of 5.29 in March 2023, suggesting a period where the market valuation contracted relative to the book value. A sharp expansion followed, with the ratio peaking at 9.55 in September 2025, reflecting a heightened market premium. In the final three quarters, the ratio contracted significantly, ending at 5.65 in June 2026, which aligns more closely with the valuation levels seen in early 2023.

Valuation Correlation

The divergence between the steady growth of BVPS and the volatile share price resulted in a non-linear P/BV trend. The peak valuation in late 2025 occurred despite the book value continuing to rise, indicating that the ratio's expansion was driven by investor sentiment and market price appreciation rather than changes in the underlying asset base.
