NEW YORK, April 9 (Reuters) - Wall Street's major indexes rose more than 1 percent each on Monday as technology stocks jumped and a softer stance by U.S. policymakers on China tariffs powered a rebound from last week's sell-off.
Led by tech, ten of the 11 major S&P sectors were higher and 29 of the 30 Dow components were in positive territory. Goldman Sachs was the biggest boost to the Dow, while gains in Apple shares led the S&P 500.
U.S. President Donald Trump's economic adviser Larry Kudlow told CNBC that the president may be open to forming an international coalition to grapple with Chinese trade issues.
"We're getting a little bit softer commentary from folks with the (Trump) administration," said Keith Lerner, chief market strategist at SunTrust Advisory Services in Atlanta. "We're basically recouping what we lost on Friday."

"Profits are a big part of the bull story," Lerner said. "We think this earnings season will re-establish the uptrend in the market."
