Constellation Energy Corporation shares jumped 6.2% on the last trading session, driven by a surge in trading activity that saw daily volume climb to 3.4 million shares compared with a 30-day average of 2.2 million. The rally pushed CEG to outperform the S&P 500 Utilities Index by nearly 4 percentage points, reflecting renewed investor interest in its nuclear power generation segment following announcements of extended plant license renewals.

Despite the recent price surge, consensus earnings estimates for CEG have been revised lower over the past two months. Analysts have trimmed full-year adjusted EPS projections by an average of 3.5%, from $4.20 to $4.05, while next fiscal year’s estimates have dipped marginally from $4.45 to $4.40. These downward revisions largely reflect anticipated higher fuel and maintenance costs at several midwestern reactor facilities, which are expected to pressure margins in the second half of the year.
