DE (IVR/IV 72/40) announces earnings on Wednesday morning before market open, so if you're going to play this, look to put on your setup on Tuesday before market close.
Here's my tentative setup, which is subject to tweaking depending on whether it moves much in Tuesday's session:
Dec 11th 68/81.5 short strangle POP%: 75% Max Profit: 107/contract BPE: ~$836 BE's: 62.93/82.57
As usual, I'll look to take this off at 50% max profit and redeploy the buying power elsewhere (assuming I can find something).
