[GIS in Wikipedia]
I shall use the OCT series of options, which trades for the last time 25 days hence, on Oct 16.

short the $52.50 puts and long the $50 puts,
sold for a credit and expiring Oct. 17.
Probability of expiring out-of-the-money
The next further in short strikes, which would increase premium, are the $57.50 calls with a 61.3% probability of expiring OTM and the $55 puts with a 68.7% probability. The probabilities in those cases are way too low for my taste.
The trade, as constructed above, has these characteristics:
The premium is $0.23, which is 9% of the width of the position’s wings.The stock at the time of analysis was priced at $56.93.
The risk/reward ratio is 9.9:1.
The zone of profit in the proposed trade covers a $3.75 move either way. The biggest immediate move after each of the past four earnings announcements was $2.35, and the average was $1.40.
Decision for My Account
I'm not going to trade GIS based on this analysis. The grid forces the short strikes to be overly wide in order to have sufficient probability of a profitable trade. The lower probability strikes would not have covered the range of maximum movement post-earnings.
My trading strategy takes the wish of Effie Trinket, the escort in Suzanne Collins distopian future, as its guide: "Happy Hunger Games. And may the odds be ever in your favor!" With GIS, clearly they are not.
