The U.S. stock market is up ever so slightly this month. And if the benchmark S&P 500 is able to eke out a gain for December, it will make history. This would be the first time ever that the blue-chip index had a gain for all 12 months of a calendar year.
Ryan Detrick, senior market strategist with LPL Research, noted in a report this week that the market has had 12-month winning streaks before. But they have never been for an entire calendar year.
