Vistra, Constellation Energy soar on clean energy bets to fuel AI tech

Nuclear Energy Emerges as Leading S&P 500 Performer Amid AI Boom

Nuclear power companies Constellation Energy and Vistra have emerged as significant winners in the S&P 500, ranking just behind Super Micro and Nvidia. This surge comes as investors expand their focus beyond semiconductors, betting on firms involved in the burgeoning artificial intelligence (AI) sector. Vistra's shares have soared by 132% this year, while Constellation Energy has seen an 81% increase, a sharp contrast to the 16.7% rise in the benchmark S&P 500. This growth is driven by the rising demand for power from data centers, manufacturers, and electric vehicle producers, necessitating a sustainable energy supply.

Investor Interest Hits Record Highs

According to a June note by Band of America, "long-only" investors and hedge fund interest in this sector have reached unprecedented levels. Over 20% of large-cap funds now own stocks in either Vistra or Constellation, up from just 13% at the start of the year. Adam Turnquist, chief technical strategist for LPL Financial, noted that the appeal lies in leveraging the clean energy theme intertwined with increasing data center demand.

US Government Support for Climate-Friendly Energy

The U.S. government's drive for major tech companies to invest in new, climate-friendly energy solutions to meet AI's growing power needs particularly benefits nuclear energy firms like Constellation and Vistra. Joseph Dominguez, CEO of Constellation Energy, noted in May that there's a symbiotic relationship between the data economy and nuclear energy, comparing it to the classic pairing of peanut butter and jelly.

Long-term Contracts and Financial Prospects

Analysts expect unregulated utilities, which allow for more competition, to enter long-term contracts with AI data centers. An example is the agreement between Talen Energy and Amazon Web Services (AWS) earlier this year, which could enhance margins and cash flow. James Thalacker from BMO Capital Markets pointed out that this deal has elevated expectations for Constellation and Vistra, both well-positioned with their nuclear facilities to undertake similar transactions.

Valuation and Market Position

Expectations that 10-year U.S. Treasury yields have peaked favor the dividend-paying utilities sector, which competes with fixed income for capital. However, some unregulated utilities' valuations are above the industry average. Constellation, for instance, trades at 25 times its 12-month forward earnings estimates compared to the S&P 500 utilities sector's 16.5 multiple, according to LSEG data. Michel Sznajer, portfolio manager at Ecofin, argues that the valuation premium is justified by the significant profit increases these companies are expected to capture due to tighter supply-demand dynamics.

Current Market Sentiment

Until May, utilities were among the best-performing S&P sectors, though they have since trimmed some gains. Nicholas Colas, co-founder of DataTrek Research, commented that the indirect strategy of investing in AI through utilities seems to have lost some momentum. While he acknowledges the utilities sector as a decent option for long-term returns, Colas favors tech stocks for more direct AI-related profits.
