NEW YORK — Oil prices are easing and helping to calm Wall Street’s worries that inflation could potentially get even worse. That has U.S. stock indexes rising early Monday, but several major chip stocks are falling again including Micron and AMD. The S&P 500 rose 0.4%. The Dow Jones Industrial Average added 625 points, and the Nasdaq composite rose 0.2%. The price of a barrel of Brent crude fell 5.1% to $83.42 after President Donald Trump said over the weekend he would hold off on ordering new strikes against Iran at the urging of allies in the region. Treasury yields fell.
