AbbVie Inc. (NYSE:ABBV)

The Price to Operating Profit (P/OP) ratio for the period examined exhibits considerable fluctuation. Initially, the ratio increased significantly before stabilizing and then experiencing another period of volatility. A general observation is that the ratio tends to be higher when the share price increases relative to operating profit per share.

Initial Increase (2013-2015)

From 2013 to 2015, the P/OP ratio increased from 10.44 to 28.64. This rise was primarily driven by a substantial increase in share price from US$38.50 to US$61.30, while operating profit per share experienced a decrease from US$3.69 to US$2.14. This indicates that investor expectations grew faster than earnings during this period.

Stabilization and Subsequent Rise (2016-2018)

The ratio decreased to 11.61 in 2016, coinciding with a decline in share price. It then rose again, reaching 19.63 in 2018. This period saw both share price and operating profit per share increase, but the share price experienced a more dramatic increase. The share price rose from US$54.29 to US$118.60, while operating profit per share increased from US$4.68 to US$6.04.

Fluctuation and Recent Trends (2019-2026)

From 2019 through 2026, the P/OP ratio demonstrated significant volatility. It decreased to 18.35 in 2019, then decreased to 10.82 in 2020, before increasing to 16.32 in 2021. A further increase to 14.21 in 2022 was followed by a rise to 24.34 in 2023 and a substantial jump to 37.26 in 2024. The most recent value, in 2025, is 26.37. These fluctuations appear correlated with changes in both share price and operating profit per share, with the 2024 peak coinciding with the highest share price recorded in the period. The share price increased from US$79.41 to US$224.81 over this period, while operating profit per share fluctuated, ending at US$8.53.

Overall, the P/OP ratio suggests periods of investor optimism and pessimism, reflected in the relationship between share price and operating profit. The ratio’s recent increase warrants further investigation to determine if it is sustainable or indicative of potential overvaluation.
