A long straddle combines a purchased call and put on the same underlying, with the same strike and expiration. It can benefit from a large earnings-related move in either direction, but the movement must be evaluated against the combined premium and the value remaining in both options.
Earnings uncertainty is already reflected in the price
Options covering an earnings announcement can include substantial event uncertainty in their implied volatility. After the announcement, that uncertainty may diminish and IV can fall sharply. This is often called volatility crush. A favorable stock move may be too small to offset the loss of time value and the change in IV.
Buying two or three weeks before earnings does not guarantee a cheaper or profitable entry. Entering earlier adds time exposure; entering later may mean paying a high event premium. The appropriate comparison is the price available, the selected expiration, and the range of outcomes being considered.
Example: paying $11 for a $100 straddle
Suppose XYZ trades at $100. A $100 call costs $6 and the matching put costs $5. One standard contract of each costs ($6 + $5) × 100 = $1,100. Assume both options expire after the earnings release. Figures below exclude transaction costs and any stock position created by exercise.
| Stock price | Combined option value | Net profit / loss |
|---|---|---|
| $90 | $1,000 | −$100 |
| $100 | $0 | −$1,100 |
| $105 | $500 | −$600 |
| $111 | $1,100 | $0 |
| $120 | $2,000 | +$900 |
The expiration breakevens are $89 and $111: the strike minus or plus the $11 combined premium. These are payoff thresholds, not forecasts or boundaries for the stock price. The maximum loss on the purchased options is the $1,100 premium, plus costs.

Closing after the announcement
If time remains, use executable option prices instead of the expiration table. For example, suppose the stock rises to $105 and the call can be sold for $5.50 while the put can be sold for $0.50. Closing both returns $600, producing a $500 loss before costs despite the 5% stock rise. These are illustrative exit prices, not a model prediction.
Closing before the announcement is a different trade from holding through it: the first depends on pre-event price and volatility changes, while the second also accepts the earnings gap and repricing afterward. Neither has a universally profitable entry date.
Checks for an earnings trade
- Confirm the release date, whether it is before or after market hours, and that the selected expiration covers it.
- Compare the combined premium, bid–ask costs and downside as well as upside scenarios.
- Define the intended exit and maximum premium committed before entering.
- Check exercise deadlines and funding if holding into expiration; a call or put exercise can create a long or short stock position.
