Clearly, I got the direction of the reaction wrong. I had a bear position; the stock moved in a bull direction. My judgement of the direction matched the chart, so I followed my rules and preferences properly.
Note that the high of the post-earnings reaction remained within the 95%, two standard deviation range, so it counts as a plain vanilla swan, not a black swan by any means.
The software company Adobe Systems Inc.a (ADBE), headquartered in San Jose, California, is best known for its ubiquitous reader that respects document formatting, its Photoshop image-editing program and the Flash video platform. The software line in its portfolio includes much more besides. Adobe publishes earnings after the closing bell today, Dec. 11. [ADBE in Wikipedia]
Implied volatility stands at 36%, in the 98th percentile of the rise that ended Oct. 15. It has declined slightly since hitting that peak.
The one standard deviation range, encompassing 68.2% of trades of the next week, implies a potential gain or loss of 5%, and the two standard deviation range, covering 95%, a 9.9% gain or loss.

The chart direction is bearish, coming off a significant reversal at $74.10 on Nov. 28. The marked stair step nature of the decline has produced a narrow chart range -- a move above $71.0 would break the downtrend; a move below $69.74 would confirm it.

ADBE has no Weeklys in its options inventory, leaving it at a choice between the Dec. 19 and Jan. 15 monthly issues. The December issue is preferable because it carries less time risk, and if I can make it work, that will be my choice.
The risk/reward is 2.6:1, well below my maximum risk of 4:1.
The position covers all of the chart range but leaves 18% of the one standard deviation range and 34% of the two standard deviation range uncovered.
Decision for My Account
There's nothing to dislike about this chart, the risks or the probabilities. I've opened a position structured as a bear call spread, as described above. It was an easy fill; I only had to lower my ask by a penny to attract a buyer.

My volatility trading rules can be read here. For a discussion of the rationale behind the rules, see my essay, "Rules for very short term trades".
My method of scoring price and volatility responses to earnings, used in the "Chart" section, is the simplest imaginable. Looking at the four most recent earnings announcements, I give one point for a rising price or rising volatility in the week after the announcement, subtract a point to a falling price or volatility, and give a zero if the response is sideways movement. I then add the four quarters together to produce separate scores for price and volatility, and then add the two to produce a combined score.
