Halliburton Co. (NYSE:HAL)

The financial data from 2006 to 2019 reveals significant volatility in valuation and profitability, reflecting the cyclical nature of the industry. The relationship between share price and earnings per share (EPS) exhibits several distinct phases of expansion, contraction, and recovery.

Price-to-Earnings (P/E) Ratio Trends

The P/E ratio experienced a period of compression between 2006 and 2008, falling from 15.03 to 9.10. This was followed by a sharp expansion between 2009 and 2011, where the ratio peaked at 24.57. A subsequent period of fluctuation occurred between 2012 and 2015, with the ratio reaching 20.81 in 2014 before dropping sharply to 10.47 in 2015.

Earnings Performance and Valuation Gaps

A divergence is noted in 2015, where EPS reached a peak of 4.12, yet the P/E ratio declined to 10.47. This suggests that despite record earnings, market sentiment was pricing in future declines. Between 2016 and 2018, the company encountered a period of negative earnings, with the most severe loss occurring in 2017 (EPS of -6.65). Consequently, P/E ratios are not applicable for these years due to the lack of positive earnings.

Share Price Correlation

Share prices fluctuated between a low of 17.01 in 2009 and a high of 54.88 in 2017. Notably, the peak share price in 2017 occurred during a period of significant negative earnings, indicating that price movements were driven by factors other than current profitability, such as future expectations or broader market trends.

Recovery Phase

A return to profitability is observed in 2019, with EPS recovering to 1.90. This recovery is accompanied by a P/E ratio of 16.54 and a share price of 31.40, signaling a stabilization of valuation metrics following the earnings volatility of the preceding three years.
