A 'swoon' in mid November isn't uncommon, especially in the Russell 2k. In fact, the probability for upside based on data from 1979 (Stock Trader's Almanac) includes 3 below 50% days in the week leading up to Nov. options expiry.

Adv/Dec (breadth) shows a rolling correction w/ big cap propping QQQ. Good news? Historically, probability gets much better from here for upside. Will history rhyme? No idea, but felt it was worth mentioning.
