Am I missing something with the short butterfly? I realize if the stock stays the same at expiration, I am out a lot of cash. But, with all the volatility and movement of prices in every direction, I'm guessing neutral short credit butterflies seem like a good idea. I'm thinking of doing a WAG credit butterfly before earnings next week. Sell 1 32.50 Call Buy 2 35.00 Calls Sell 1 37.50 Call All for net credit of $0.55 (midpoint). B/E points would be $31.82 and $37.51, implying that is what I expect the move to be after earnings. Earnings should produce a large move in the stock, so this would be a neutral position. Do you think this is a good spread?
