Friday is also the final trading day of November, and barring an epic selloff the Dow and S&P 500 will post a second straight month of gains and 8th in 11 months this year. The Nasdaq will also post a second month of gains, but only its 7th in 11 months (it was down in April while the others were higher).
The Dow will end November having not lost ground in back-to-back sessions since Oct. 15-16.
