Norfolk Southern Corp. (NYSE:NSC)

The financial data from 2006 to 2022 indicates a consistent long-term increase in both share price and operating profit per share, though the relationship between these two metrics—expressed as the Price to Operating Profit (P/OP) ratio—experienced several distinct phases of volatility, contraction, and expansion.

Share Price and Operating Profit Trajectory

A sustained upward trend is observed in both share price and operating profit per share over the 16-year period. The share price increased from $50.30 in 2006 to $270.42 by 2022, while operating profit per share grew from $5.14 to $18.55. This indicates a general growth in both the market valuation of the company and its underlying operational efficiency.

Valuation Contractions and Market Anomalies

A significant contraction in the P/OP ratio occurred in 2009, reaching a period low of 4.23. This decline was driven by a sharp drop in share price to $35.56, occurring even as operating profit per share rose to $8.42. This divergence suggests that market sentiment during that period was decoupled from operational performance, resulting in a temporary undervaluation of operating profits.

P/OP Ratio Expansion and Peak

The P/OP ratio entered a phase of steady expansion beginning in 2017, rising from 11.33 to a peak of 20.61 in 2021. The 2021 peak represents the highest valuation multiple in the analyzed period, caused by a combination of rising share prices and a simultaneous decline in operating profit per share to $11.92. This period reflects a significant premium placed on the share price relative to the actual operating earnings.

Recent Stabilization

By 2022, the P/OP ratio moderated to 14.58. This correction was primarily driven by a strong recovery in operational performance, with operating profit per share reaching a period high of $18.55. This increase in profit acted as a stabilizing force, bringing the valuation multiple down from its 2021 peak despite the share price continuing to climb to $270.42.
