Options traders are pricing a 5.7% move in General Motors Co. stock when the automaker reports quarterly results on July 21 before the market opens, based on options data compiled by Bloomberg. That implied magnitude reflects market expectations for volatility around the news event but does not indicate the direction of any move.
Looking back over the last eight earnings announcements for GM, the actual intraday stock changes have surpassed the size implied by options on five occasions. The specific comparisons are as follows:
- On April 28, 2026, the implied move was 6.0% but the stock declined 2.0%.
- On January 27, 2026, the implied move was 6.2% and the stock rose 6.9%.
- On October 21, 2025, the implied move was 6.1% and the stock jumped 19.8%.
- On July 22, 2025, the implied move was 5.9% and the stock fell 8.3%.
- On May 1, 2025, the implied move was 5.8% but the stock dropped 1.7%.
- On January 28, 2025, the implied move was 5.5% and the stock declined 1.8%.
- On October 22, 2024, the implied move was 5.5% and the stock rose 10.5%.
- On July 23, 2024, the implied move was 5.1% and the stock fell 5.9%.
These examples illustrate two important points for market participants: implied move estimates quantify expected magnitude but not direction, and past outcomes have sometimes diverged materially from the options-implied numbers. Traders and investors monitoring GM around the July 21 report should be mindful that the stock has a recent history of reactions both smaller and substantially larger than what the options market priced in.
Summary
The options market is pricing a 5.7% move for General Motors when it reports earnings on July 21 before the market opens, per Bloomberg options data. Historical patterns across the last eight earnings cycles show the stock exceeded the implied magnitude in five instances, demonstrating potential for notable volatility around the report.
Key points
- Options-implied move for GM on July 21: 5.7% (from Bloomberg data).
- In five of the past eight earnings reports, GM's actual stock move was larger than the options-implied move.
- Sectors impacted: automotive equities and broader equity market volatility around major corporate earnings events.
Risks and uncertainties
- The options-implied percentage reflects expected magnitude but not the direction of the move - actual results may move the stock up or down.
- Historical outcomes show material divergence from implied moves, meaning the options market estimate may understate or overstate potential stock reactions; this creates execution and risk-management challenges for equity and options traders.
