The Price to Operating Profit (P/OP) ratio exhibits significant volatility over the analyzed period, reflecting a complex relationship between market valuation and operational performance. While the share price followed a consistent long-term upward trajectory, increasing from 20.78 US$ in 2012 to 167.16 US$ in 2024, the operating profit per share fluctuated substantially, leading to inconsistent valuation multiples.
- Historical Ratio Fluctuations
- Between 2012 and 2016, the P/OP ratio shifted from 3.86 to a peak of 7.22 in 2014 before returning to 3.86 in 2016. A notable spike occurred in February 2017, where the ratio reached its historical maximum of 11.10. This increase was driven by a reduction in operating profit per share to 4.51 US$, while the share price simultaneously rose to 50.03 US$, indicating a period where the market valuation was high relative to diminished operational earnings.
- Operational Anomaly and Recovery
- A critical disruption in the ratio is observed in February 2021, where the P/OP value is absent. This is attributed to a significant operational loss, with operating profit per share falling to -18.80 US$. Following this trough, the ratio reappeared in 2022 at 9.79 as operating profits returned to positive territory at 7.61 US$ per share.
- Recent Valuation Compression
- From 2022 to 2024, a sharp compression of the P/OP ratio is evident, falling from 9.79 to 4.16. This downward trend was not caused by a decline in share price—which actually rose from 74.46 US$ to 167.16 US$—but by a massive surge in operating profitability. Operating profit per share peaked at 48.19 US$ in 2023, causing the P/OP ratio to drop to 2.60, its lowest point in the observed sequence, before settling at 4.16 in 2024.
In summary, the data indicates that recent years have been characterized by a decoupling of share price growth and the P/OP ratio, as exceptional growth in operating profits has outpaced the increase in market price, leading to a more conservative valuation multiple despite record-high share prices.
