In the U.S. bond market, Treasury yields eased after held its main interest rate at a two-decade high but gave some indication that lower rates may soon be on the way.

A batch of softer-than-expected released during the morning strengthened hopes that inflation is slowing enough to convince the Fed to cut rates at its next meeting in September, and Fed Chair Jerome Powell said policy makers are “getting closer to the point� where they'll be comfortable enough to cut.

“You would think, base case, that policy rates would move down from here, but I don't want to try to give specific forward guidance about when that might be, the pace at which it might happen," Powell said. "That's really going to depend on the economy, and that's highly uncertain.�

How such Big Tech stocks perform matters a lot because they’re Wall Street’s most valuable companies, and that gives them the biggest sway on the S&P 500. A handful of these stocks, known as the “Magnificent Seven,� drove the U.S. stock market to dozens of records this year, even as many other stocks struggled under the weight of high interest rates. But they ran out of momentum this month amid criticism they had grown too expensive and expectations had run too high.

They helped offset a 3.4% drop for Altria Group after the maker of cigarettes and smoke-free products fell short of expectations for profit and revenue in its latest quarter.

In the bond market, the yield on the 10-year Treasury eased to 4.11% from 4.14% late Tuesday. It’s been falling from 4.70% in April as a raises expectations for coming cuts to interest rates by the Federal Reserve.

Yields fell in the morning after a report showed U.S. employers spent less in total pay and benefits for workers during the spring than economists expected. Another suggested hiring by employers outside the government was a touch weaker than expected.

While workers would surely like stronger such numbers, it could be the type of “Goldilocks� data that Wall Street is looking for: not so strong that it pushes upward on inflation but not so weak that it raises worries about a recession.

Some of Wednesday's strongest action was in the oil market, where prices tumbled after Hamas’s top political leader Ismail Haniyeh died in a in the Iranian capital early Wednesday, Iran and the militant group said.
