Opened: XBI February 18th 100/132 Short Strangle... for a 2.69 credit.
Comments: And back into XBI (rank/implied 54/37) after closing out my January position. 2.69 credit on buying power effect of 11.30 (on margin); 23.8% ROC as a function of buying power effect; 11.9% at 50% max. As usual, will look to take profit at 50% max; manage sides on either approaching worthless or test.
