Quote from Coolio:
I started out trading this in May with a 44 Call Calendar spread out to SEP. When my short 44 for May melted away I just went "diagonal" and sold the May 40 instead, then when that melted away, sold the Jun 40.
In between there I made a little 2 day bearish swing trade with a put to make a little side money.
Whew 30! Sounds like I should consider my plan to layer on bear call spreads !!! This implosion sounds like it is happening sooner rather than later. The open interest on the entire put side is enormous with a 7.64 put to call ratio.
Another cheap little trade which allows one to capitalize on this .. is buying a 30 put calendar by selling the JUN 30 and buying the 30 SEP put. That gives you -11.62 Delta, +.61 Gamma, +.13 Theta and + 4.29 Vega.
Just the associated volatility explosion alone will help this make money and this trade sorta says "I know it'll reach 30 eventually, I just don't know when" whereas the butterfly makes a definite timing prediction (and pays off accordingly).
