Click to view the earnings moves in GIS
General Mills just released its latest earnings—and the stock has popped 3% today, defying options market expectations and adding new intrigue to a name that often keeps traders guessing. So, is today’s move a sign of more action to come, or is history not on the bulls’ side?
GIS Earnings Recap: Beating the Odds or Defying Gravity?
Today, General Mills (NYSE: GIS) reported second-quarter results, reaffirming its fiscal 2026 outlook despite a tough consumer backdrop. The company is doubling down on brand investment, even as recent divestitures and cost pressures hit top-line and profit metrics. Net sales declined 7% year over year, while adjusted operating profit dropped 20% in constant currency—reflecting expected growing pains as the company restructures for long-term growth. Diluted EPS fell to $0.78, a 45% drop, while adjusted EPS of $1.10 slid 21%. The outlook? Organic sales are projected to be flat to slightly negative for the year, with profit metrics still pressured by transition costs and investments.
The real story, however, may be in the options and historical price patterns.

How GIS Stock Typically Reacts to Earnings: The Data Doesn’t Lie
If you’re trading earnings or just watching for outsized moves, General Mills’ past can be revealing. Here’s how GIS stock usually responds on earnings days:
| Stock Performance | Earnings Move | Open Gap | Open to High | Open to Low | Open to Close |

What Happens After Earnings? The Drift Tells a Story
The earnings day is just one part of the narrative. Here’s what typically happens after the results are out:
| Stock Performance | 1 Day After Earnings | 2 Days After Earnings | 3 Days After Earnings | 1 Week After Earnings | 2 Weeks After Earnings |
|---|---|---|---|---|---|
| Average Return | 0.0% | 0.0% | +0.1% | +0.8% | +0.5% |
| % of Moves Up | 27.3% | 27.3% | 45.5% | 54.5% | 36.4% |
| % of Moves Down | 72.7% | 72.7% | 54.5% | 45.5% | 63.6% |
Most GIS earnings days see an initial downside move. Yet, from the close to a week out, returns are flat to slightly positive on average. About half the time, GIS posts a gain over the following week, though negative follow-through is more common right after the announcement.
Takeaway: What’s Next for GIS?
While General Mills’ shares outperformed options traders’ expectations today, history shows this is the exception rather than the rule for GIS on earnings days. The options market is active, and big bets like the December 2025 47.5 calls may be looking for continued upside or simply hedging a new regime of volatility.
If you’re following GIS, remember that while today’s bounce looks strong, the longer-term trend after earnings often turns flat, with most big gains or losses realized by the close of trading on announcement day. Will today’s relative strength continue, or will history repeat itself? Dive deeper into the historical earnings performance here, and watch the options tape for new clues.
