In this article, we are going to discuss the energy stocks that are losing this week.
The S&P Energy index fell by 1.04% between February 11 and February 18, compared to a decline of 0.87% witnessed by the broader S&P 500 during the period.
The recent plunge in natural gas prices has contributed to this downturn, with US natural gas futures currently hovering near a 4-month low of just under $3 per MMBtu, down 43% since January 22. The prices have been weighed down by a combination of factors, including the milder shift in weather, which has reduced the demand for heating. Moreover, there has been a rapid recovery in supply following Winter Storm Fern, with average production in the Lower 48 states rising to 108.7 billion cubic feet per day so far in February, up from 106.3 bcfd last month.
On the other hand, WTI crude oil futures are currently trading above $66 per barrel, having surged by over 16% since the beginning of 2026. Crude oil prices have been pushed up by the ongoing tensions between Washington and Tehran, with concerns that a potential American attack may lead to Iran blocking the Strait of Hormuz, which handles around a quarter of the world’s seaborne oil trade. A blockade on the all-important waterway could lead to major supply disruptions, further driving up prices.
