ROKU (83/94) announces on Wednesday after market close and with rank/implied greater than 70/50, it's an ideal play for contraction post-announcement. The pictured setup is a September 20th 75/80/135/140 iron condor, paying 1.67 at the mid price (one-third the width of the wings). Look to take profit at 50% max (.83/$83 assuming a mid price fill).
Taking the top spot again this week for rank/implied among the exchange-traded funds is GDXJ (92/37) with the >70% probability of profit September 20th 36/45 short strangle paying 1.31 (.75/$75 at 50% max) and delta/theta metrics of 2.02/3.16.
Lastly, with the pop in last week, consider a assumption play in either VXX or UVXY (i.e., either short call verticals or long put verticals) with the short leg in the money, the long out and that pays at least one-third of your spread in credit (or for which you have to pay less than two-thirds the width in debit). For example, the VXX Sept 20th 25/27 short call vertical is paying .67 at the mid price with a break even at 25.67. Conversely, the VXX Sept 25/27 long put vertical costs 1.36 to put on with a 25.64 break even and a max profit potential similar to that of the same-strike short call vertical (.64/$64). For the bolder at heart, the VXX Sept 22/24 long put vertical costs .95 to put on, making it a risk one/make proposition on the notion that implodes fairly quickly back to its pre-pop levels, taking the VIX derivatives with it.
