The Dow Jones Industrial Average jumped on Thursday to record territory, fueled by a rebound in shares of Goldman Sachs, Wednesday’s worst performer, and a rally in UnitedHealth. The Dow components combined to contribute more than 50 points to the blue-chip’s 110-point rally. For Goldman Sachs Group Inc. GS, -0.79% the rise marks a comeback for shares that logged Wednesday’s worst performance, among the Dow DJIA, +0.29% components, cutting 50 points from the benchmark, and pushing the investment bank’s stock to a six-month low, amid worries about ultralow bond yields [BX: TMUBMUSD10Y] and fretting about a slump in second-quarter trading activity, following warnings from a pair of bank executives. On Thursday, Goldman was adding 27 points, while UnitedHealth Group Inc. UNH, -0.11% was contributing about the same amount to the Dow’s clamber higher. Overall, the stock market was getting a boost from an upbeat private-sector employment rate, ADP, which may augur well for the Labor Department’s closely watched nonfarm-payrolls report due Friday. The Dow’s advance also comes as the S&P 500 index SPX, +0.37% and the Nasdaq Composite Index COMP, +0.94% touched fresh intraday records. For its part, the Dow was on pace to close above its own closing high, up 0.5% at 21,120, which would mark its first record finish since March 1.
