Corning Inc. (NYSE:GLW)

The financial data reveals a period of significant volatility in the Price to Operating Profit (P/OP) ratio, largely driven by fluctuations in operating profitability rather than consistent movements in share price. While the share price experienced a general upward trajectory over the long term, the P/OP ratio exhibited sharp spikes during years of depressed operating earnings.

Share Price Trends

The share price demonstrated a cyclical pattern, starting at 24.70 US$ in 2006 and reaching a peak of 41.29 US$ in 2022. Notable lows occurred in 2009 (10.14 US$) and 2013 (12.78 US$). Despite these fluctuations, the price recovered and maintained a higher baseline from 2017 onwards, ending the period at 32.18 US$ in 2024.

Operating Profit per Share Performance

Operating profit per share grew from 0.38 US$ in 2006 to a high of 2.50 US$ in 2022. This growth was not linear; substantial contractions are observed in 2010 (0.25 US$) and 2021 (0.66 US$). These profit dips created significant imbalances in the valuation multiple during those specific fiscal years.

Price to Operating Profit (P/OP) Analysis

The P/OP ratio shows extreme variance, with peaks in 2006 (64.50), 2010 (69.85), and 2021 (55.67). These peaks coincide with periods where operating profit was disproportionately low relative to the share price. Conversely, a period of relative valuation stability is observed between 2011 and 2020, where the ratio largely fluctuated within a narrow range of 12.25 to 19.26.

In the most recent three-year window, the P/OP ratio has trended upward, rising from 16.54 in 2022 to 30.86 in 2024. This recent increase is attributable to a declining trend in operating profit per share (dropping from 2.50 US$ to 1.04 US$) while the share price remained relatively resilient, indicating a contraction in operating efficiency relative to market valuation.
