Why These Energy Stocks are Losing This Week

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

The overall energy sector surged by 4% over the last week, compared to gains of just under 1% by the broader market. However, some sub-sectors lagged behind, with uranium being one of them.

Uranium stocks posted a massive rally earlier this month following the announcement of a new pilot program by the Department of Energy to accelerate the development of advanced nuclear reactors and strengthen domestic supply chains for nuclear fuel. The strategic move is a part of the Trump administration’s efforts to reduce reliance on foreign sources of enriched uranium and critical materials, especially given the current geopolitical landscape. However, uranium stocks have declined since then, probably due to investors cashing in their profits.

It must also be mentioned that the uranium price has declined by just under 10% over the last month, and is currently down by around 13.7% compared to the same period last year.
