I've skewed the zone of profitability somewhat to the downside in order to account for the general bearish tone of the market, leaving $138 at the top of the one standard deviation range unprofitable. Moreover, 43 cents of the downside is also beyond the profit zone.
It's not an optimal position. However, I ought to get a bump from the collapse in volatility after the earnings announcement, and volatility itself, while high relative to its own past, is in absolute terms somewhat on the low side, which ought to help the chance that the price will stay within the profit zone.
