HAL

Over the past six months, Halliburton Co. (HAL) stock has experienced fluctuations, with a 15.13% year-to-date return and a 47.75% increase over the last 12 months, but a 9.93% decrease in the past month as of October 10, 2026. Several events have impacted the stock price, including softer fiscal Q3 2026 guidance, which led to a 6.76% premarket decline despite stronger-than-expected Q2 results, with projected sequential revenue decreases for both Completion and Production and Drilling and Evaluation segments. Other factors include a moderated pace of expansion in the broader oilfield services sector, volatile oil prices, declining natural gas prices, and the company's decision in October 2026 to withdraw from the Sea Lion oil project off the Falkland Islands due to legal and regulatory risks from Argentina, which contributed to an 11.7% decline over the past month.
