Procter & Gamble Co. (NYSE:PG)

The valuation of the company exhibits three distinct phases characterized by significant shifts in the relationship between market price and book value. An initial period of high valuation in 2005 transitioned into a decade of relative stability, followed by a substantial expansion in the price-to-book multiple starting in 2016.

Share Price Trajectory

The share price demonstrated a long-term upward trend, rising from 55.64 US$ in 2005 to a peak of 168.06 US$ in 2023. While the growth was gradual between 2005 and 2016, a more aggressive acceleration occurred between 2017 and 2023. A moderate correction is observed in the final two periods, with the price settling at 148.01 US$ by 2026.

Book Value per Share (BVPS) Evolution

A sharp increase in BVPS occurred between 2005 and 2006, jumping from 7.10 US$ to 19.81 US$. For the subsequent decade, BVPS remained relatively stable, fluctuating within a range of approximately 21 US$ to 25 US$. From 2016 onward, the BVPS entered a period of relative stagnation and slight volatility, dipping to 18.71 US$ in 2020 before recovering to 23.27 US$ by 2026.

Price to Book Value (P/BV) Dynamics

The P/BV ratio began at a high of 7.84 in 2005, primarily due to the low BVPS at that time. From 2006 to 2015, the ratio compressed and stabilized, generally remaining between 2.38 and 4.23, indicating a consistent market valuation relative to the company's equity. Starting in 2016, there was a sustained expansion in the multiple, peaking at 7.87 in 2024. This surge indicates that the market began assigning a significantly higher premium to the company's intangible assets, brand equity, or future earnings potential relative to its accounting book value. A slight contraction is noted in 2025 and 2026, with the ratio declining to 6.36.

The divergence between the accelerating share price and the relatively stagnant book value per share after 2016 explains the substantial increase in the P/BV ratio. The current valuation levels remain significantly higher than the historical averages observed between 2006 and 2015, reflecting a shift in investor sentiment or a change in the company's asset structure.
