March 2025 Seasonal Pattern of US Stock Indices | Jeff Hirsch

Rather turbulent in recent years, with wild fluctuations and large gains and losses, March has been experiencing some significant end-of-quarter hits. In post-election years since 1950, March has tended to open strongly, and this strength has generally persisted until shortly after mid-month (as indicated by the dashed arrow below). At that point, the major indexes lost momentum and closed out March with some choppy trading. In contrast, over the past 21 years, March has trended lower through mid-month before rallying in the second half.

 March strong early-month, mid-month losses with choppy trading,
often rally after Quadruple Witching (March 21), likely sharp decline the week after.

March is a particularly busy month. It marks the end of the first quarter, which brings with it quarterly Quadruple Witching (Friday, March 21) and an abundance of portfolio maneuvers from Wall Street. In recent years, March Quad-Witching Weeks have been quite bullish, but the week after has been nearly the exact opposite, with the DJIA down 22 of the last 37 years—and often down sharply.
