That being said, the "Top 10" list isn't entirely bereft of possibilities, depending on your risk tolerance and aversion to roller coasters.
For example, GPRO may be worth a assumption play here on the notion that Christmas sales of its drones will be "brisk," something we probably won't know unless GPRO discloses its unit sales before its Q4 announcement next year. The nearest to the 20-delta strike short put, 45 DTE , however, is the Dec 30th 8.5, which would bring in .36 ($36)/contract at the mid -- not exactly something that gets me excited. Even assuming I wanted to go nondirectional (short strangle/straddle, iron condor/fly), I can't squeeze enough out of those setups premium wise to make it worthwhile.
VRX is, well, VRX . The Dec 30th 14.5 short put (currently the 19 delta) goes for .66 ($66) at the mid price. That isn't bad, but I have to put up with sitting on pins and needles for 5 weeks or more with that setup. The alternative would be to go with a defined risk setup (not keen on being caught undefined in a potential whipsaw). Even there, however, an iron condor won't pay out at least 1.00 in credit without forcing the wings in beyond the 1 SD (I prefer more room with volatile biotech), and I'm not sure that I would want to go with the narrower breakevens of a fly, in spite of the fact that the credit I'd receive at the door would be more than sufficient. (A Dec 30th 13/18/18/23 iron fly would bring in 2.78, for example).
Well, what about AMD? That's in the list ... . Like its semicon counterpart, NVDA , AMD's been on a rip and the place to have gotten in was lower for a assumption play (scratches "short put" off his list). And nondirectional doesn't pay enough: the Dec 30th 8.5 short straddle would bring in a 1.44 credit at the mid (I like to get at least 2.00 out of those); the 7/10.5 short strangle, .40 at the mid. Defined risk (flies, condors) will bring in even less.
CLF? Same deal (can't get much out of the 45 DTE 20 delta short put; short straddle/strangle, iron condor/fly bring in too little premium).
Sometimes, these holiday weeks are best for hand sitting ... . Looks like this is going to be "par for the course."
