$ALXN #ShortStrangles – Covered some November strangles to release some margin.
Bought to close ALXN Nov 17 2017 80/165 Strangles @ 1.35.
Originally Sold the Puts on 05/23/2017  @ 2.10 as a #FallingKnife trade.
Then as the stock recovered sold the Calls on 07/27/2017 @ 2.35 and again on 07/28/2017 @ 2.85.
The Strangle may have expired, but it’s a long time until November, and the puts were so low, they weren’t really protecting the calls anymore.
