NEW YORK — U.S. stocks are edging lower Thursday amid the countdown for Wall Street’s main event this week, a speech by Federal Reserve Chair Jerome Powell coming on Friday.

The S&P 500 was 0.3% lower in midday trading, though still within 1.1% of its all-time high set last month. The Dow Jones Industrial Average was down 177 points, or 0.4%, as of 11:25 a.m. Eastern time and the Nasdaq composite was 0.5% lower.

Mixed Economic Data Impacts Market

Stocks fell as Treasury yields rose in the bond market following some mixed data on the U.S. economy, which has been slowing under the weight of high interest rates meant to get inflation under control.

One report showed slightly more U.S. workers applied for unemployment benefits last week than expected. The number is still low relative to history, but the uptick could signal a job market that continues to cool.

A second report, meanwhile, suggested U.S. business activity remains deeply split. Growth for services businesses is accelerating, according to preliminary data from S&P Global Market Intelligence. But the country’s manufacturing, which has been one of economy’s areas hit hardest by high rates, appears to be contracting at a more severe rate.

Overall, the data suggested the U.S. economy is still growing but pointed to some fragility.

“Growth has become increasingly dependent on the service sector as manufacturing, which often leads the economic cycle, has fallen into decline,” said Chris Williamson, chief business economist at S&P Global Market Intelligence.

Anticipation Builds for Powell’s Speech

The Fed has pulled its main interest rate to the highest level in more than two decades in hopes of slowing the economy by just enough to stifle inflation but not so much that it causes a recession. With inflation slowing, the wide expectation is for the Federal Reserve to cut interest rates at its next meeting in September, which would be the first such easing since the COVID crash of 2020.

That’s why so much attention is on Jackson Hole, Wyoming, where Powell will speak Friday at an economic symposium that’s been home to big Fed policy announcements in the past. The hope is Powell will give clues about how quickly and deeply the Fed may cut rates to ease conditions for the economy.

One danger is if expectations for coming cuts to rates have gone overboard among investors, something that has frequently been the case historically. That would mean the drop in Treasury yields since the spring may have been overdone. The drop has helped pull mortgage rates lower, which in turn helped sales of previously occupied homes stop a four-month slide in July.

Mixed Corporate Earnings Reports

In the meantime, U.S. companies continue to report mostly better-than-expected profits for the springtime.

Internet-connected exercise company Peloton soared 30.3% after it topped sales forecasts and lost less money in the quarter than analysts were expecting. It achieved modest revenue growth for the first time in more than two years.

Another winner of the pandemic that saw its fortunes weaken afterward, Zoom Video Communications, also rose following its profit report. It climbed 12.7% after delivering better earnings and revenue for the latest quarter than expected.

But more stocks were falling on Wall Street than rising, including Nvidia. It erased an early gain to slip 0.4% ahead of its own highly anticipated profit report coming next week.

Also on the losing side of Wall Street was Snowflake, which fell 13.1% despite topping analysts’ expectations for profit and revenue in the latest quarter. It gave a forecast for product revenue in the current quarter that fell short of what analysts were estimating.

Advance Auto Parts tumbled 17.2% after its profit for the latest quarter came up short of Wall Street’s expectations. It cited a “challenging demand environment” and cut its forecast for profit over the full year well below what Wall Street was expecting.

In the bond market, the yield on the 10-year Treasury rose to 3.86% from 3.80% late Wednesday.

In stock markets abroad, indexes made mostly modest moves across Asia and Europe. South Korea’s Kospi rose 0.2% after the Bank of Korea decided at its monetary policy meeting to keep rates unchanged.

Hong Kong’s Hang Seng was an outlier and jumped 1.4%.
