In this article, we are going to discuss the energy stocks that are losing this week.
While the S&P 500 had a strong week with gains of over 2.5% from November 19 to 26, the S&P energy index lagged, with a decline of almost 0.9% over the same period. A major cause of this decline is the recent fall in global oil prices, with WTI crude oil futures currently hovering near a 1-month low of just over $58 per barrel. The primary reason behind this is a potential breakthrough in the Russia-Ukraine conflict, which could lift Western sanctions on Russian crude.
Moreover, according to the latest data from Kpler, the supply growth in the global LNG market is set to outpace the demand increase, which could lead to an LNG glut from the end of 2026 onwards. The excessive supply will lead to a decline in prices, with Kpler forecasting benchmark Asian spot prices to fall from about $12 per million British thermal units (mmBtu) in 2025 to an average of $10 next year.

10. Ecopetrol S.A. (NYSE:EC)
Share Price Decline Between Nov. 19 – Nov. 26: 5.46%
Ecopetrol S.A. (NYSE:EC) is among the largest companies in Colombia and one of the leading integrated energy groups on the American continent, with more than 19,000 employees.
Ecopetrol S.A. (NYSE:EC) fell short on profit expectations in its Q3 results announced on November 13, with the company’s net profit falling by 30% YoY on the back of weaker sales volumes and lower crude prices.
Ecopetrol S.A. (NYSE:EC)’s total production volume in the quarter dipped by 0.4% YoY to 751 mboed, but still came in near the top of its annual guidance range, driven by key fields in Colombia such as Caño Sur, CPO-09, as well as the Permian in the United States. However, local sales volumes declined by 2.9% YoY, while international sales volumes were down 12.8% compared to last year, primarily due to higher throughput at the refineries and variation in logistics chain inventories.
Global crude oil prices hovering around a one-month low have also put pressure on Ecopetrol S.A. (NYSE:EC), as a potential peace deal in the Russia-Ukraine conflict could ease restrictions on Russian oil and add to the supply glut.
9. Atlas Energy Solutions Inc. (NYSE:AESI)
Share Price Decline Between Nov. 19 – Nov. 26: 5.55%
Atlas Energy Solutions Inc. (NYSE:AESI) engages in the production, processing, and sale of mesh and sand used as proppants during the well completion process in the Permian Basin of West Texas and New Mexico.
Atlas Energy Solutions Inc. (NYSE:AESI) continued on its downward trajectory this week after Goldman Sachs analyst Ati Modak downgraded the stock from ‘Neutral’ to ‘Sell’, while also reducing its price target from $12 to $8. The firm remains cautious about AESI’s FY 2026 growth and forecasts its EBITDA to be around 10% below consensus, on the back of lower sand prices, slower volume growth, and challenging logistics profitability.
This comes after Piper Sandler also lowered its price target on Atlas Energy Solutions Inc. (NYSE:AESI) from $12 to $10 on November 17, but maintained its ‘Neutral’ rating. Earlier on November 14, Barclays also downgraded AESI from ‘Equal Weight’ to ‘Underweight’, while trimming its price target from $11 to $7.
The bearish analyst sentiment stems from Atlas Energy Solutions Inc. (NYSE:AESI) posting unimpressive results for its third quarter earlier this month, with the company falling short of expectations on both earnings and revenue.
