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

The recent plunge in crude oil and natural gas prices has pushed the S&P 500 Energy index to fall by over 2.9% between December 12 and December 19, underperforming the overall S&P 500. That said, it has been a positive few days for the American nuclear energy and uranium sector, especially with the recent rebound in nuclear fuel prices.

The American nuclear energy renaissance continues, and it was reported on December 17 that the federal government granted 20-year license extensions for another two nuclear facilities in Illinois, following through on President Trump’s order in May to cut down on regulations and fast-track new licenses.

Efforts to revive the sector also extend across the border, and on December 19, it was announced that New York has signed an MoU with the Canadian province of Ontario to collaborate on advancing nuclear energy technologies, including small modular reactors (SMRs) and large-scale nuclear facilities. It is worth noting that Ontario is already leading the way in nuclear technology and is currently building the first small modular reactors in the G7.

Topping our list of Energy Stocks that Gained the Most This Week is Sable Offshore Corp. (NYSE:SOC), an independent upstream company focused on developing the Santa Ynez Unit in federal waters offshore California.

There were reports earlier this month that Sable Offshore Corp.
