Opening (Margin): /ES December 30th 1900 Short Put

... for a 3.15 credit.

Comments: Adding a smidge back in, after taking off a couple of my higher risk rungs in October. 1.575 ($157.50) max on BPE of 13.75 ($1375); 11.5% ROC (50.0% annualized) as a function of buying power effect; 5.7% at 50% max (25.0% annualized). A basic bet that the S&P doesn't lose 50% of its value by year end.
