They call it the “January Effect.”

Whether it’s the by-product of those Wall Street guys reinvesting their legendary end-of-the-year bonuses or individual investors jumping back into the market after selling for year-end tax reasons, the Dow Jones Industrial Average historically gets a nice little (and sometimes huge) bump during the first month of the year.

The Dow rallied up 415.35 points, or 3.4%, in January – the best January percentage gain since 1997.
