The Standard & Poor’s 500 index rose to an all-time high, as Apple Inc. boosted technology companies, and health care shares rallied amid earnings. Boeing Co.’s results dragged the Dow Jones industrial average lower.

“The general tone of earnings has been positive not just on the bottom line but also top-line, and we’ve seen inflation numbers that gave comfort to those who believe the market will be supported by the Fed,” Russ Koesterich, chief investment strategist at New York-based BlackRock Inc., said via phone.

The IMF cut its U.S. growth forecast for this year to 1.7 percent from 2 percent predicted in June, citing a first-quarter contraction.

The S&P 500 has advanced 7.5 percent this year amid better-than-estimated corporate earnings and central bank stimulus, as the U.S. economy shows signs of recovering from a 2.9 percent contraction in the first quarter. The gauge trades at 18.4 times the reporting earnings of its members, the highest since 2010.

“There may be some times when the geopolitical landscape hogs the spotlight, but it’s always about earnings, and they’re coming in better than expected,” said Karyn Cavanaugh, senior market strategist at New York-based Voya Investment Management LLC. Voya oversees about $220 billion. “People say we’re at all-time highs and that we have to come down, but we’re not out of the ball park with valuations yet.”
