The biggest day-after-Christmas rally in stock-market history wasn’t enough to convince investors that Wall Street has seen the worst of a year-end selloff that’s threatened to end the second-longest bull market. In fact, it might have done the opposite.

The Dow Jones Industrial Average DJIA, -1.82%[1]  was trading sharply lower[2] Thursday, giving back a chunk of Wednesday’s 1,086-point rally, a gain of 5%. The S&P 500 SPX, -1.89%[3]  was also following its tandem 5% jump with a decline, while the Nasdaq Composite COMP, -2.39%[4]  was relinquishing a portion of its gains. Wednesday’s rally marked a rebound from a Monday selloff that represented the worst Christmas Eve performance for all three indexes in history.
