Uranium companies make top gainers list as Nuclear Energy Index jumps 4% overnight

Deep Yellow, SILEX Systems and Bannerman Energy were among the top gainers on Wednesday after the STOXX Nuclear Energy Index (NEI) benchmark jumped more than 4% overnight.

There hasn’t been any one clear catalyst to drive the surge. Often, when giants like Canada’s Cameco or Kazakhstan’s Kazatomprom declare some kind of production or supply chain issue, that’s enough to cause ASX uranium companies to take a jog.

In this instance, no such disclosure. With energy volatility heightened in the ongoing US-Iran war, uranium prices have been swinging along with other forms of fuel; there is also the established thematic around nuclear power being a boon for AI companies.

Perhaps one catalyst for the overnight NEI volatility is that the US government’s Department of Energy has thrown US$4.2B to US company Vistra to do just that. There was also a landmark 20 year deal announced by Google overnight.

Wall Street is viewing Vistra as a beneficiary of the development of nuclear power reactors specifically to power data centres while the Google deal is more of a broadstroke show of authenticity behind the idea that nuclear power will come to power AI data centres.

Of course, no data centre operators are currently using nuclear energy to power such assets; but like much of the ‘AI trade,’ the proposed value is built-into medium and long-term future projections.

That’s neither here nor there – for ASX uranium investors, and long-patient nuclear loyalists, Wednesday’s moves have surely been welcome developments.

While gains pared off heading into mid-arvo trades, early in the Wednesday intraday session, the biggest nuclear names on the ASX all shot to the top of the biggest gainers boards.

The fact gains pared off mid-arvo is of course evidence of something I often like to write – when it comes to the uranium trade, investors need to be trick.

Of all baskets of stocks that tend to benefit from swings on energy commodities and benchmarks like the NEI, uranium tends to be the most fickle.
