NEW YORK — Pressure from another increase in Treasury yields weighed down stocks on Wall Street Tuesday. The S&P 500 fell 0.3 percent after spending most of the morning wavering. The Dow Jones Industrial Average fell 232 points, or 0.5 percent, as of 1:45 p.m. Eastern time. The Nasdaq composite fell 0.2 percent. Major indexes shifted lower after a quiet morning as increased pressure from the bond market undercut much of the heavy lifting being done by several technology behemoths. Nvidia gave up an early and influential gain and was mostly unchanged. Broadcom gave up much of its gain and was up most recently by 1.6 percent. Stocks remain under pressure as oil prices swing sharply as the U.S. war with Iran drags on, helping to push Treasury yields to their highest levels in 24 years. The price of Brent crude oil in the most actively traded part of the oil market fell 1 percent to $96.84 a barrel. It briefly climbed above $100 on Monday before prices eased a bit, but they are still well above the roughly $72 it cost before the U.S. and Israel attacked Iran in late February. Mediators cont
