Correlation of ExxonMobil stock with WTI
The correlation coefficient of ExxonMobil with WTI stands at 0.48 for the past three months. The correlation value of ExxonMobil stock and oil prices show that the stock price of ExxonMobil has moved in line with WTI prices to a certain degree. This means that changes in oil prices can explain around 48% of the changes in ExxonMobil stock price over the past three months.
However, this figure has risen to 60% over the past 15 days, indicating a strengthening of correlation, which could be due to the impact of Hurricane Harvey. ExxonMobil, which has a robust upstream segment, will likely see the impact of pressurized oil prices in its next results, and its downstream facilities located on the US Gulf Coast have also been impacted.
