CEG Earnings Pop: Another Rally—But Will It Stick This Time?
Constellation Energy (NASDAQ: CEG) delivered its latest earnings today, seeing the stock jump +3.8% to $303.26. While that’s an impressive move, history suggests the real intrigue is in how CEG typically reacts on earnings days—and just as important, what happens in the days that follow.
If you’re wondering whether this is an outlier or part of a recurring trend, you’re not alone. Let’s dig into the numbers and see what history has to say about CEG’s earnings-day stock behavior and the aftermath.
Historical Earnings-Day Moves: Upside Bias Prevails
Over the last 12 earnings reports, CEG has shown a strong upward bias on earnings days. On average, shares gained +3.7%, with 75% of events resulting in a positive move from the previous close. Even more interesting: while the average gap at the open was a slight negative (-0.5%), the stock often rallied throughout the session for an average open-to-close return of +4.1%. A remarkable 91.7% of those sessions closed higher than the open!
Here’s a snapshot of the key stats for CEG on earnings days:
| Stock Performance | Earnings Move | Open Gap | Open to High | Open to Low | Open to Close |

How Dramatic Are the Moves? Measuring the Swings
It’s not just the average move that matters—sometimes, magnitude is everything. CEG’s absolute average move on earnings day clocks in at 5.9%, with some reports seeing up to 16.9% in either direction. On the flip side, the smallest move was just 0.4%, showing a wide range of possible outcomes:
| Stock Performance | Earnings Move | Open Gap | Open to High | Open to Low | Open to Close |
|---|---|---|---|---|---|
| Absolute Average Return | 5.9% | 2.6% | 5.8% | 1.6% | 4.6% |

| Min Absolute Return | 0.4% | 0.4% | 1.3% | 0.0% | 0.5% |
Post-Earnings Hangover? The Rally Doesn’t Always Last
While CEG has a clear upward tilt on earnings day, the good times often don’t persist. Historically, the stock sees only a slight average gain of +0.6% one day after earnings, with gains occurring just 36.4% of the time. Two weeks after, the average move actually tilts negative at -2.2%.
| Stock Performance | 1 Day After Earnings | 2 Days After Earnings | 3 Days After Earnings | 1 Week After Earnings | 2 Weeks After Earnings |
|---|---|---|---|---|---|
| Average Return | +0.6% | -0.1% | -0.1% | -0.2% | -2.2% |
| % of Moves Up | 36.4% | 36.4% | 54.5% | 54.5% | 54.5% |
| % of Moves Down | 63.6% | 63.6% | 45.5% | 45.5% | 45.5% |
Options Market Pulse: Eye on the 27-Feb-26 320 Call
It wasn’t just the stock price that was active today. Option traders pushed volumes to 11,485 contracts, with the most action centered on a single contract:
| Option Contract | 27-Feb-26 320 C |
|---|---|
| Volume | 26 |
| VWAP price | 1.09 |
| Open interest | 1,183 |
| Yesterday's closing price | 2.08 |
For context, the market was expecting a ±7.2% move, meaning today’s actual jump of +3.8% underwhelmed relative to options pricing—possibly pointing to a post-earnings volatility crush as premiums recalibrate.
The Bottom Line
CEG’s earnings-day performance is typically strong, with an impressive track record of gains and clear momentum from the open to the close. But for those chasing after the pop, history shows that the upside rarely persists beyond that first electric burst—so keep an eye on the follow-through and what options traders are signaling.
