In this article, we are going to discuss the energy stocks that are gaining this week.

The S&P Energy index posted impressive gains of 7.32% between February 2 and February 9, against a decline of 0.17% by the overall S&P 500 during the period.

The surge was primarily driven by rising crude oil prices amid ongoing tensions between Washington and Tehran, as markets weighed the risk of the US imposing further sanctions on Iranian oil and Iranian authorities responding by intercepting tankers through the vital Strait of Hormuz.

On the other hand, the price of natural gas slumped to a three-week low on February 9 as investors weighed the impact of warmer weather forecasts across the United States, which are likely to suppress the commodity’s demand for heating and power generation. Moreover, recent data from Baker Hughes revealed a significant increase in drilling activity in the Haynesville Shale, raising concerns about future supply and putting further downward pressure on natural gas prices.

The energy sector also received a boost from the impressive Q4 2025 earnings recently posted by the country’s major refiners. The fuelmakers reported better-than-expected profits during the quarter as product margins, spurred largely by the ongoing Russia-Ukraine war, rebounded from the multi-year lows witnessed in 2024 when earnings eased from post-pandemic highs.

Moreover, the recent regime change in Venezuela is expected to significantly benefit American Gulf Coast refiners in the coming months, as their facilities are well equipped to process the cheaper, heavy crude coming from the South American country.
