Neat idea and hardly(to my knowledge) a crowded institutional idea either. How do look at structuring this in a cost effective manner? I gave it a quick glance and put it on the "take a look at" reminder list for later. But briefly, couldn't you construct a cheaper expression with an outright short and some calls to hedge? Or is this a "big expected downside so go really far out of the money" situation?
I just buy long out of the money puts.
Very interesting - what dates you buying on the puts?
