Why These Energy Stocks are Gaining This Week

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

The American uranium sector received a massive boost this week after the price of the nuclear fuel soared to over $80 per pound, the highest in ten months. The rally follows a statement by US Energy Secretary Chris Wright that the country is looking to boost its strategic uranium reserves to buffer against Russian supplies and increase confidence in the long-term prospects of nuclear power generation.

Mr. Wright stated the following at the IAEA’s annual general conference in Vienna:

“We’re moving to a place — and we’re not there yet — to no longer use Russian enriched uranium. We hope to see rapid growth in uranium consumption in the US from both large reactors and small modular reactors. The size of that right buffer would grow with time. We need a lot of domestic uranium and enrichment capacity.”

Following these comments by the Trump administration’s top energy official, physical fund Yellow Cake raised $125 million to purchase 1.33 million pounds of uranium from Kazatomprom at a discounted price, echoing similar moves from industry heavyweight Sprott that triggered a rally in the nuclear fuel prices earlier in June.
