Procter & Gamble Co. (NYSE:PG)

The Price to Sales (P/S) ratio exhibits a distinct two-phase trajectory over the observed period, transitioning from a decade of relative stability to a period of significant valuation expansion followed by a recent moderate correction.

Stability and Consolidation Phase (2005–2015)

Between 2005 and 2015, the P/S ratio remained within a tight corridor, primarily fluctuating between 1.93 and 2.85. During this interval, the market valuation closely tracked sales per share, with the ratio dipping to its lowest point of 1.93 in 2009, coinciding with a sharp decline in share price. The valuation remained largely range-bound, suggesting a consistent market perception of the revenue-generating capacity relative to equity value.

Valuation Expansion Phase (2016–2024)

A structural shift in valuation occurred in 2016, where the P/S ratio jumped to 3.51 and continued an upward trend, peaking at 4.71 in 2024. This expansion was driven by share price growth that significantly outpaced the growth of sales per share. For example, while sales per share increased from 24.47 in 2016 to 35.70 in 2023, the share price rose more aggressively from 85.99 to 155.28 in the same period, resulting in a higher multiple applied to each dollar of sales.

Recent Correction and Normalization (2025–2026)

A downward trend in the P/S ratio is observed in the final two years of the sequence, descending from 4.71 to 3.95. This contraction is attributed to a decline in the share price, which fell from 168.06 to 148.01, despite a continued steady increase in sales per share, which reached 37.44 by 2026.

The correlation analysis indicates that the P/S ratio was historically driven by sales performance until 2016, after which it became more sensitive to share price volatility and market sentiment, leading to a heightened valuation regime that only recently began to normalize.
