The Dow blew past the latest in a series of milestones Tuesday, but was unable to close above 26,000 as early gains gave way to weakness. The S&P 500 SPX, -0.35% and Nasdaq COMP, -0.51% retreated from all-time highs to end lower. The Dow DJIA, -0.04% saw a gain of more than 282 points, or 1.1%, at its intraday peak of 26,086.12, but ended the day down 10.33 points at 25,792.86. That was the average’s biggest one-day reversal in percentage terms since Feb. 10, 2016, according to WSJ Data Group. If the Dow had closed above 26,000 on Tuesday, it would have marked just seven trading days since it first closed above the previous 1,000-point milestone at 25,000. That would have been the fastest such move between 1,000-point milestones on record, albeit a feat that grows markedly less impressive in percentage terms the higher the Dow climbs. For now, the record remains the 23 trading days the Dow took to move from 24,000 to 25,000. via
