Some of the optimism that sent stocks rallying a day earlier drained out of Wall Street, as airstrikes continue to batter Iran and missiles target sites across the Middle East. Oil prices got back to rising Tuesday, and U.S. stocks are returning some of their gains. The price for a barrel of Brent crude rose 3.5% and is back above $103 per barrel, a day after slumping more than 10%. The S&P 500 fell 0.4%, giving back more than a third of its gain from the day before. The Dow Jones Industrial Average dropped 351 points, and the Nasdaq composite fell 0.5%. Treasury yields rose.
