Another consideration is the 2 days that SPX stayed below 800 last year. If there were enough buyers there on Jan 875 call or higher strike, those options will be so expensive that keeping op ex price around 850 may be in order.
We're still in the downward trending channel in NQ, but we're right in/slightly above some heavy support. If they're going to reverse this thing and drive us higher out of this downtrend today is the day... especially after seeing the bulls stage a big reversal from the overnight sell-off. The RTH charts will be virtually unchanged by the open and thats bullish. Perfect channel, perfect 5-wave symmetry, heavy support... lets see what happens.
