The Price to Operating Profit (P/OP) ratio, calculated from the provided share price and operating profit per share figures, exhibits considerable fluctuation over the observed period. Initial values indicate a relatively high valuation compared to operating profitability, followed by periods of compression and expansion. A general observation is that the ratio is sensitive to changes in both share price and, more significantly, operating profit per share.

Initial Period (2006-2008)

The P/OP ratio began at 17.67 and increased to a peak of 22.76 before declining to 10.41. This initial increase coincided with a modest rise in share price and operating profit per share. The subsequent decrease was driven by a significant drop in share price, despite an increase in operating profit per share.

Period of Low Valuation (2009-2010)

The years 2009 and 2010 demonstrate a period of lower P/OP ratios, bottoming out at 6.06. This corresponds with a period of increased operating profit per share, but a depressed share price. The ratio then increased slightly, reflecting a modest increase in share price.

Volatility and Expansion (2011-2014)

From 2011 to 2014, the P/OP ratio experienced substantial volatility. A peak of 19.51 was observed in 2012, followed by a decline and then a sharp increase to 15.06 in 2014. This period was characterized by fluctuating share prices and operating profit per share, with 2014 showing a particularly strong increase in operating profit per share driving the ratio higher.

Stabilization and Subsequent Decline (2015-2019)

The P/OP ratio stabilized somewhat between 2015 and 2019, fluctuating between approximately 8.61 and 10.78. While share price and operating profit per share both experienced changes, they largely offset each other, resulting in a relatively consistent valuation ratio.

Recent Fluctuations (2020-2024)

The period from 2020 onwards shows significant volatility. A dramatic spike to 31.88 occurred in 2021, coinciding with a substantial decrease in operating profit per share and a relatively stable share price. The ratio then decreased to 7.32 in 2022, followed by a missing value for 2023, and a subsequent increase to 5.12 in 2024. The most recent value of 9.56 suggests a moderate valuation relative to operating profit.

Overall, the P/OP ratio demonstrates a lack of consistent trend. It appears to be more reactive to changes in operating profit per share than share price, particularly in periods of significant fluctuation. The ratio’s sensitivity suggests that investor perception of future profitability plays a key role in valuation.
