Opened (Margin): GLD May 19th 185/Sept 15th 210 LPD*... for a 19.98 debit.
Comments: Taking a bearish assumption directional shot in GLD here on strength. Buying the back month -90 delta put and selling the front month +30 to emulate the delta metrics of a covered put (i.e., short a one lot of stock + short a put).
Cost basis of 19.98 with a 190.02 break even on a 25 wide. 5.02 ( SGX:502 ) max profit, assuming a finish sub-185, 25.1% ROC at max; 12.6% at 50% max.
Will generally look to roll out the short put at 50% max to the shortest duration 30 delta strike that is at or below my break even. With the back month out in September, I have quite a few opportunities to reduce cost basis if the setup doesn't work out immediately.
