NEW YORK — U.S. stocks crept to a record as the S&P 500 nudged higher after a quiet Tuesday of trading. The main measure of Wall Street’s health rose 0.2% to finish just above its all-time closing high, set last month. Most of the stocks within the index rose as it danced around the milestone through the day.

Wall Street is retreating from its record as a slide for Walmart weighs on U.S. stock indexes Thursday. The S&P 500 was down 0.6% in morning trading after setting all-time highs in each of the last two days.

U.S. stock indexes are wavering on Wall Street Wednesday. The S&P 500 was mostly unchanged, a day after setting an all-time high. The Dow Jones Industrial Average was down 122 points, or 0.3%, as of 12:18 p.
