The Price to Operating Profit (P/OP) ratio exhibits significant volatility over the analyzed period, characterized by extreme peaks and intervals of relative stabilization. While the share price demonstrates a consistent long-term upward trajectory, the valuation relative to operating profit reveals periods of substantial divergence, suggesting fluctuating market expectations regarding future growth.

Valuation Spikes and Divergence

Two primary anomalies in the P/OP ratio are observed in 2014 and 2021. In 2014, the ratio peaked at 162.89, driven by a sharp increase in share price to 170.40 alongside a decrease in operating profit per share to 1.05. A similar pattern emerged in 2021, where the P/OP ratio climbed to 124.33 as the share price reached a historical high of 494.24 while operating profit per share declined to 3.98. These spikes indicate periods where market valuation significantly decoupled from current operating performance.

Operating Profitability Trends

Operating profit per share was inconsistent during the early years, recording negative values in 2006 and 2008. However, from 2009 to 2020, a general growth trend is evident, with profit per share rising from 0.66 to a peak of 6.70. This growth phase provided a fundamental basis for the increase in share price, although the pace of price appreciation often outstripped profit growth.

Periods of Relative Valuation Stability

Between 2012 and 2013, the P/OP ratio remained relatively low and stable, ranging between 30.11 and 31.41. A more prolonged period of moderate stability occurred from 2015 to 2020, during which the ratio generally fluctuated between 37.71 and 55.49. During this window, the expansion of the share price was more closely aligned with the steady increase in operating profit per share.
