Opening (IRA): TSLA March 21st 305/2x315/320 BWB*... for a 1.25 credit.
Comments: I don't do these very often, but decided to putz with one here. The setup consists of two parts -- a long put vertical (the -315P/320P) and a short put vertical (the 305P/-315P), one of which is wider than the other. I wrapped it around the 30 delta/expected move strike at the 315 and erected wings out from there.
Although the ROC at max is sexy and alluring, it is illusory, since it would require a finish between the break even at 308.75 and 315 which is a fairly small landing pad when you've launched your rocket from 38 days out in time. Consequently, you generally want to look to take profit either at 50% max of the credit received or for something decent, but far less than the max if presented with the opportunity.
From a trade management standpoint, these generally work or they don't, although I will consider rolling up the 305 put to the 310, assuming I get an opportunity to do so for a debit that is less than the credit received. This would convert the setup into a "free fly," since both wings would be of the same width (i.e., the max loss of the short put vertical would be equal to the max loss of the long put vertical).
Metrics:
Max Profit: 6.25
Max Loss/Buying Power Effect: 3.75
ROC at Max: 167%
Break Even: 308.75/share
* -- Broken wing butterfly.
