Notes: Selling some more SLV (30-day at 47.7%), as well as collating my "ladder" into a single post. Will add in a December monthly "rung" once that becomes available, assuming the hangs in there. Collected 1.74/contract in total.
Here's the way I look at this trade relative to one put on in GLD:
Currently, GLD is trading at 178.16, SLV at 22.65, so GLD is about 8 times the notional value of SLV here. The November 20th GLD 15 delta 184 strike is paying 1.14; the November 20th SLV 14 delta strike at 19. .31 and 8 x .31 = 2.48. Consequently, you're getting more than 2 x "bang for your buck" in risk premium as a function of stock price in SLV than GLD here, primarily due to the differential between SLV 30-day IV at 47.7% versus GLD's 20.4%.
