New York, Feb 14, 2026, 15:51 EST — Market’s done for the day.
- Constellation Energy shares ended Friday up, bouncing after a volatile session.
- The latest SEC filing shows a passive stake crossing the 5% mark.
- Tuesday, traders are back, eyeing data-center power needs and grid regulations once again.
Shares of Constellation Energy Corp (CEG) ended Friday up 4.46% at $288.43, logging a gain that stood out on a subdued day for the broader market. Volume was unusually high. Still, the stock is a long way off its October high—a sharp reminder of just how quickly sentiment around power stocks linked to the data-center wave can shift. (MarketWatch)
Why does it matter right now? Investors are sorting out which players can actually deliver large, reliable amounts of electricity for the data center buildout—and at what cost. That’s driving both utilities and independent power producers into the same trade: it’s infrastructure, it’s politics, it’s classic supply and demand all rolled together.
Constellation finds itself near the heart of the debate, operating a sprawling generation fleet and competing in fast-moving markets. The bull case? Long-term contracts, bigger capacity payments. But there’s a flip side: regulation, permitting backlogs, and buildout delays risk dragging a “deal wave” into a drawn-out slog.
Capital International Investors disclosed holding 17,170,795 shares of Constellation—good for a 5.5% stake in the class—as of December 31, 2025, according to a Schedule 13G filed on Feb. 12. Unlike an activist’s 13D, this form signals the investor isn’t aiming to control or sway the company. (SEC)
For traders, the point isn’t so much who’s buying—it’s what the move signals: heavyweight players are still stepping up with large positions despite the recent choppiness. There’s also the question of whether all the new chatter around power contracts actually translates to earnings, not just buzz.
It’s not great timing. With U.S. markets shut on Monday for Presidents Day, investors will have to mull over the ownership filing and fresh grid-policy talk until trading kicks off again Tuesday. (Kiplinger)
PJM Interconnection—the largest U.S. grid operator—is fueling some of the speculation as it develops a plan to accommodate massive data center demand. “A flurry of major data center-slash-power deals” could hit in the coming months, according to James West, managing director at Melius Research. But there’s a catch, said Rick Pederson, chief strategy officer at Bow River Capital: permitting and interconnection delays could throw up “real world obstacles.” (Reuters)
But things could easily shift in the opposite direction. PJM’s proposals face approval hurdles, and even strong projects can run aground once transmission bottlenecks, siting disputes or political headaches appear. Should power prices dip or data-center demand lose steam, that trade’s premium may evaporate fast.
Come Tuesday, eyes will be on Constellation again—plus names like Vistra and Talen—as investors look for any sign this “bring your own generation” trend is pushing deals toward long-term bilateral contracts. Fresh SEC filings or analyst notes could hit as well. In thin liquidity, a crowded trade can move fast.
Earnings will be the next big test for Constellation. According to FactSet data cited by Markets Insider, the company is set to report on Feb. 19. Investors are watching for fresh details on contracted demand, pricing changes, and any clues tied to shifting PJM rules. (markets.businessinsider.com)
