A 2.5% drop in the Dow, adding up a 550-point decline, could be unsettling. Those sorts of tumbles are not infrequent, with 564 such moves of that magnitude occurring in the Dow since 1901. The most recent slump of at least 2.5% was on June 24, 2016, when the Dow tumbled about 610 points, or 3.4%, a day after U.K. citizens voted to end the country’s membership in the European Union. There were 3 falls for the Dow of at least 2.5% in 2015.
