If history is an indication, the stock market could extend its rally into December.
U.S. stocks finished the shortened-holiday week with another gain, up for eight consecutive weeks. The S&P 500 set its longest winning streak in nearly 10 years, while it was the Dow's longest consecutive weekly increase in three years. Both indexes are up 6.8 percent and 6.7 percent, respectively, in that period.
Since the 1900s, December is the best month for the Dow, and second-best month for the S&P 500 and Nasdaq. Historically, all three indexes have gained on average between 1 and 2 percent, respectively.
