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

The recent military action by the US in Venezuela has caused shockwaves across the global oil industry, as the South American country sits atop the largest oil reserves in the world. The White House has now taken control of sales of sanctioned Venezuelan oil ‘indefinitely’, calling for American oil companies to rebuild the country’s crumbling oil infrastructure and bring its heavy crude to Gulf Coast refineries, which were already designed to process this oil in the first place.

While this could present a serious opportunity for certain American oil producers, refiners, and oilfield service providers, oil traders are concerned by the prospects of large amounts of Venezuelan crude entering an already oversupplied market. As a result, the WTI crude oil futures have fallen to just over $56 per barrel, only slightly above the 4-year low they hit last month.

While the American oil giants are still assessing the situation, given the political uncertainty in Venezuela and their discouraging past experience in the country, President Trump remains optimistic. He has already claimed that the US oil industry would be ‘up and running’ in Venezuela within 18 months and has even announced a deal to import up to 50 million barrels of Venezuelan crude. However, oil traders view this move as adding supply to the world’s largest oil consumer, putting further downward pressure on prices.

8. EOG Resources, Inc. (NYSE:EOG)

Share Price Decline Between Dec. 31 – Jan. 7: 2.34%

EOG Resources, Inc. (NYSE:EOG) is one of the largest crude oil and natural gas exploration and production companies in the United States, with proved reserves in the US and Trinidad.

On January 5, Bernstein analyst Bob Brackett trimmed the firm’s price target on EOG Resources, Inc. (NYSE:EOG) from $144 to $126, while keeping a ‘Market Perform’ rating on the shares. The revised target still indicates an upside of almost 23% from the current share price. The analyst believes that 2026 will be a ‘transitional year’ for shale operators such as EOG, as shale production is expected to plateau and then decline. This will lead producers to assume various risks as they seek to replace inventory, including acquisition, exploration, and geopolitical risks. Bernstein has begun the new year with a balanced view for oil, expecting rough times in the near term but more strength later.

EOG Resources, Inc. (NYSE:EOG) has also come under pressure from the recent fall in global crude oil prices. Ann Janssen, the finance chief of EOG, stated on January 7 that the decline is driven by oversupply and the prospect of higher production from Venezuela and could persist for several more quarters.

7. Sunrun Inc. (NASDAQ:RUN) 

Share Price Decline Between Dec. 31 – Jan. 7: 5.65%

On January 7, Deutsche Bank lowered its price target on Sunrun Inc. (NASDAQ:RUN) from $20 to $19, while maintaining a ‘Hold’ rating on the shares.

However, on a positive note, Sunrun Inc. (NASDAQ:RUN) announced on January 6 that it has formed a joint venture with HA Sustainable Infrastructure to finance distributed energy assets across the United States. Under the agreement, HASI will invest $500 million in the JV over an 18-month period, with the intention of financing 300 MW of solar and energy storage capacity. While HASI’s equity investment will monetize a part of long-term customer cash flows from the underlying assets, Sunrun will be able to retain a significant long-term ownership stake in the assets. Moreover, the JV will provide the solar energy company with greater flexibility in arranging senior project debt.

Danny Abajian, Chief Financial Officer of Sunrun Inc. (NASDAQ:RUN), commented:

This innovative financing structure with HASI is a first-of-a-kind for residential storage and solar financing. We appreciate the collaboration with the HASI team and continued innovation to unlock additional value for both companies along with our customers across the country. This partnership provides for an efficient capital structure, which we anticipate will allow aggregate proceeds that are equal to or better than Sunrun’s traditional financing arrangements. This structure is consistent with our strategy to utilize various structures and a diverse set of capital providers to finance our growth.

With gains of almost 99% last year, Sunrun Inc. (NASDAQ:RUN) is included among the 11 Best Performing Energy Stocks in 2025.
