Constellation Energy Corporation (CEG) closed at $300.16 on October 7, 2026, after rising 12.12% in the prior 24-hour period. The move extended a strong recent run, with the stock also up 13.42% over the past seven days.
Despite the pronounced short-term momentum, CEG's 30-day change stood at a more modest 0.40%, indicating that much of the recent price appreciation was concentrated in the past week rather than spread evenly across the past month.

The single-session gain of more than 12% marks one of the stock's more notable daily moves in recent memory, contributing meaningfully to its weekly advance and reinforcing the concentration of buying activity in the near term.
