I submitted a short article on shake shack at 11.50 AM on 03/01/2016: however, don't know if it will be published before the market close.
In the article I outline a trade involving SHAK's June 17 $42.50 puts which closed at $6.35 on 03/03/2016. I would sell the puts if SHAK reaches $21/share. $21/share is my short term price target for SHAK. The trade represents a risk reward of 2.5 to 1. Ultimately, I believe SHAK has an intrinsic value of $12.70/share.
My main article is much more elaborate so if you are reading this you should look for my article on SHAK. I just want to put this out there before the market closes just in case my piece is not published in time.
Disclosure: I/we have no positions in any stocks mentioned, and no plans to initiate any positions within the next 72 hours.
