Frankly, I think tomorrow might be better. And I'd love to play QCOM short.
QCOM is currently trading at about $45.80.
There's lots of OI and current activity on the February 45 strike (AAONI), which is currently ATM. Bid:1.55 Ask: 1.80
Personally, I think I'd feel more comfortable playing this slightly ITM. The Feb 50 strike puts (AAONJ) have a good OI as well and the delta is higher, so these will move more significantly with a drop in the stock.
