Microsoft Corp. (NASDAQ:MSFT)

The valuation multiples across all tracked metrics exhibit a cyclical pattern characterized by an initial contraction through late 2022, a period of significant expansion through mid-2025, and a sharp downward correction entering 2026.

Price to Earnings (P/E) Ratio

The P/E ratio began at 34.30 in September 2021, experiencing a decline to a trough of 26.71 by December 2022. A subsequent recovery phase saw multiples expand to a peak of 38.37 in September 2025. This was followed by a rapid contraction, with the ratio falling to 21.68 by June 2026, marking the lowest valuation level in the analyzed period.

Price to Operating Profit (P/OP) Ratio

Closely mirroring the P/E trend, the P/OP ratio declined from 31.35 in September 2021 to 21.76 in December 2022. The ratio regained strength, peaking at 30.20 in December 2023 and maintaining relatively high levels through September 2025. A steep decline occurred thereafter, ending at 18.68 in June 2026.

Price to Sales (P/S) Ratio

The P/S ratio shifted from 13.21 in September 2021 to a low of 8.83 in December 2022. An upward trajectory followed, reaching a peak of 13.70 in September 2025. Similar to other metrics, the ratio entered a period of compression in 2026, settling at 8.74 by June.

Price to Book Value (P/BV) Ratio

The P/BV ratio showed the most pronounced long-term decline. After starting at 15.32 in September 2021 and reaching a secondary peak of 12.74 in December 2023, the ratio underwent a consistent and severe reduction, dropping to 6.56 by June 2026.

Overall, the data indicates a period of valuation inflation that culminated in late 2025, followed by a systemic correction across all common stock valuation ratios. The simultaneous decline in P/E, P/OP, P/S, and P/BV during the final quarters suggests a significant adjustment in market pricing relative to fundamental financial performance.

The valuation trajectory of the common stock reflects three distinct phases: an initial period of contraction, a subsequent phase of expansion, and a final period of sharp compression. While earnings per share maintained a consistent upward trajectory throughout the entire period, the share price and the resulting price-to-earnings ratio exhibited significant volatility.

Share Price Performance

A cyclical pattern is observed, beginning with a decline from 310.11 USD in September 2021 to a trough of 242.04 USD by December 2022. This was followed by a sustained recovery and growth phase, peaking at 541.55 USD in September 2025, before trending downward to 390.54 USD by June 2026.

Earnings Per Share (EPS) Growth

EPS demonstrated a steady and uninterrupted increase, rising from 9.04 USD in September 2021 to 18.01 USD by June 2026. This represents a consistent improvement in underlying profitability per share, which continued regardless of market price fluctuations.

Price to Earnings (P/E) Ratio Dynamics

The P/E ratio fluctuated between a high of 38.37 in September 2025 and a low of 21.68 in June 2026. Initial contraction was noted through late 2022, followed by a valuation expansion phase coinciding with the price surge between 2023 and 2025. The most significant shift occurred in the final three quarters of the period, where a declining share price coupled with rising EPS led to a rapid compression of the valuation multiple.

The divergence between EPS and the P/E ratio in the final period indicates that the market valuation of earnings decreased even as actual earnings continued to grow. The lowest valuation multiple of the entire analyzed period was recorded in June 2026, suggesting a transition toward a more conservative valuation framework despite peak earnings performance.

The financial trajectory from September 2021 to June 2026 is characterized by a consistent expansion in fundamental operating efficiency contrasted with significant volatility in market valuation. While operating profit per share followed a linear growth path, the Price to operating profit (P/OP) ratio experienced multiple cycles of contraction and expansion, ending the period at a valuation low despite record profitability.

Operating Profit per Share Trend

A continuous and uninterrupted upward trajectory is observed in operating profit per share, which increased from 9.89 USD in September 2021 to 20.91 USD by June 2026. This steady growth represents a more than twofold increase in operational earnings per share over the analyzed timeframe, indicating robust and stable internal profit generation.

Share Price Volatility

The share price exhibited substantial fluctuations throughout the period. An initial decline was noted from 310.11 USD to a trough of 242.04 USD in December 2022. This was followed by a prolonged recovery and growth phase that peaked at 541.55 USD in September 2025, before a subsequent downward correction led to a closing price of 390.54 USD in June 2026.

Price to Operating Profit (P/OP) Ratio Analysis

The P/OP ratio mirrored the volatility of the share price, as the steady growth of operating profits was frequently offset by market price swings. The ratio initially declined from 31.35 to 21.76 by December 2022. A secondary peak was reached at 30.20 in December 2023, followed by a period of relative stability between 27.94 and 29.68 through September 2025. The final phase of the data shows a sharp compression in the ratio, falling to 18.68 by June 2026. This final decline indicates that the market valuation contracted significantly even as operating profits reached their highest levels, resulting in the lowest P/OP multiple of the entire period.

The valuation analysis reveals a cyclical pattern in the Price to Sales (P/S) ratio, characterized by an initial contraction, a period of significant expansion, and a subsequent decline toward the end of the observed period. While sales per share maintained a consistent upward trajectory, the P/S ratio fluctuated primarily in response to volatility in the share price.

Sales per Share Performance

A steady and uninterrupted increase in sales per share is observed from September 30, 2021, through June 30, 2026. Revenue efficiency grew from 23.48 US$ to 44.69 US$, representing a consistent growth trend that remained independent of share price fluctuations.

Share Price Volatility

The share price exhibited significant variance, starting at 310.11 US$ and reaching a trough of 242.04 US$ in December 2022. A strong recovery followed, with the price peaking at 541.55 US$ in September 2025, before declining to 390.54 US$ by June 30, 2026.

P/S Ratio Trends

The P/S ratio underwent three distinct phases. First, a valuation contraction occurred between September 2021 and December 2022, where the ratio dropped from 13.21 to 8.83. Second, a valuation expansion phase took place from March 2023 through September 2025, with the ratio climbing to a peak of 13.70. Finally, a sharp compression is noted in the final three quarters, with the ratio falling to 8.74 by June 2026.

Valuation Correlation

The divergence between the consistently rising sales per share and the fluctuating P/S ratio indicates that the valuation was driven more by market sentiment and share price movements than by organic revenue growth. The final decline in the P/S ratio suggests a market correction where the share price decreased despite the continued increase in sales per share.

The analysis of the Price to Book Value (P/BV) ratio reveals a long-term contraction in the valuation premium over the analyzed period from September 2021 to June 2026. While the share price experienced significant volatility, the P/BV ratio transitioned from a peak of 15.32 to a period low of 6.56, indicating a shift in how the market values the company's net assets relative to its market capitalization.

Book Value per Share (BVPS) Growth

A consistent and uninterrupted upward trend is observed in the book value per share. BVPS increased from 20.24 USD in September 2021 to 59.58 USD by June 2026. This steady growth indicates a continuous accumulation of net assets and an increase in the intrinsic accounting value of each share throughout the entire period.

Share Price Volatility and Valuation Peaks

The share price demonstrated substantial fluctuation, characterized by a decline through late 2022, a recovery peak of 541.55 USD in September 2025, and a subsequent correction to 390.54 USD by June 2026. Despite these price surges, the P/BV ratio did not return to its 2021 highs, suggesting that the growth in book value began to offset the impact of share price increases on the overall valuation multiple.

P/BV Ratio Compression

The P/BV ratio exhibits three distinct phases. First, a sharp decline occurred between September 2021 and December 2022, where the ratio dropped from 15.32 to 9.84. Second, a period of relative stability and modest recovery followed from March 2023 through December 2023, peaking at 12.74. Third, a sustained downward trajectory emerged from March 2024 through June 2026, with the ratio falling to 6.56. This final phase of compression is particularly notable as it occurred despite the share price reaching its absolute peak in late 2025.

The convergence of a steadily rising book value and a declining P/BV ratio suggests a valuation normalization. By the end of the period, the market price was significantly closer to the accounting book value than it had been at the start of the analysis, reflecting a decrease in the premium investors were willing to pay over the company's tangible net assets.
