It is reporting earnings on Thursday, August 18, after market close:(Source: TD Waterhouse)As evident from the above, the company beat earnings estimates in 37% of time in the last eight quarters, showing in-line results in the rest of time, and has seen modest volatility in the market price of its stock over the last three months: The market participants expect the following numbers over the next few quarters, including the upcoming one:(Source: TD Waterhouse)Market data show that the August options are a bit overvalued:(Source: TD Waterhouse)The two-day straddles (options with a strike price of $25.50 and expiring on August 19, 2016) are worth around 5.5% of the current market price of the stock. Historically, the stock has been more volatile than that on a monthly basis over the last year:(Source: Google Finance. Calculations by author)As you can see, the stock has had a monthly standard deviation of 11.6% over the last 52 weeks, while the straddle expiring in two days has an implied monthly volatility of around 3.6% (calculated based on 2 business days remaining until expiration), also including volatility from the earnings event this week. I therefore see signs of modest overvaluation in these options. Hence, selling the straddles is a good idea from a theoretical standpoint.Investors may also be interested in selling calendar spreads to capitalize on the higher implied volatility of the front month's options:(Source: optionsprofitcalculator.com)The risk-return profile of this trade looks like this:(Source: optionsprofitcalculator.com)As you can see from the above illustration, the "window of safety" is around 13.4%. This means that the stock has to move roughly 7% in either direction from the current price by expiration in order for investors to start losing money. The risk-reward ratio of around 1:1.43 is below-average with this type of option strategies and is deemed attractive in the case of a relatively low volatility stock like The Gap Inc.
