On the page 11 Rearden is talking about news for earnings of ADT on 31 July. I am not sure but I think Rearden is not saying ADT will go down always. I think Rearden bet his puts of August will be in the money for that time. In that time he can win.
I have to disagree about buying flat puts before an earnings announcement...to me that is pure gambling...if you have a long term view then fine...or if you doing straddles or something like that then maybe...but estimatting earnings is rolling the dice.
I know RM has a more macro view of why it should be lower...but Trader fighter arent u risking cash right before earning for no real reason?
