Wall St indexes slip with rates, Middle East in focus

Wall Street's three major indexes closed down around 1.0 per cent on Monday while Treasury yields rose, as traders tamped down bets for Federal Reserve interest-rate easing and worried about the Middle East conflict's impact on oil prices.

While waiting for quarterly earnings season and fresh economic data, investors also braced for another big hurricane, Milton, which is expected to hit the United States this week. Relief efforts are under way after Helene, a Category 4 hurricane, killed more than 200 people across six states.

Further dampening sentiment on Monday was an order from a US judge for market heavyweight Alphabet's Google to overhaul its mobile-app business to give Android phone users more options. Analyst reports also spurred selling of Amazon.com and Apple Inc.

After Friday's stronger-than-expected jobs report, traders pulled back from bets for a 50-basis-point rate cut in November. They were pricing in an 86 per cent chance of a 25-basis-point cut and a roughly 14 per cent chance the central bank would not cut rates at all, according to the CME's FedWatch tool.

The change in rate-cut expectations caused US Treasury yields to rally, with the yield on benchmark 10-year notes exceeding 4.0 per cent for the first time in two months.

Besides next month's Fed meeting, investors are waiting for the Consumer Price Index inflation reading for September and the kickoff of third-quarter earnings season with reports from banks, both due this week.

"It's a combination of things over the last couple of days: the jobs report, the hurricane damage, the elevated energy prices and negative comments about some of the large-cap tech names," said Michael James, managing director of equity trading at Wedbush Securities in Los Angeles.

"All of that combined just makes for a nervous day, and the Google headlines tipped things over to more aggressive selling in the last hour."

James pointed to the Middle East conflict as a concern for US investors who are worried about the war's economic impact, including rising oil prices.

Investors continue to fret about how Israel would respond to Iran's missile strikes. On Monday, Lebanon's armed group Hezbollah fired rockets at Israel's city of Haifa while Israeli forces looked poised to expand ground raids into south Lebanon.

The Dow Jones Industrial Average fell 398.51 points, or 0.94 per cent, to 41,954.24, the S&P 500 lost 55.13 points, or 0.96 per cent, to 5,695.94 and the Nasdaq Composite lost 213.94 points, or 1.18 per cent, to 17,923.90.

The CBOE Volatility index, Wall Street's fear gauge, closed up 3.4 points at 22.64, marking its biggest one-day points gain in more than a month and its highest closing level since August 8.

Among the S&P 500's 11 major industry indexes, only energy advanced, finishing up 0.4 per cent. US crude futures settled up 3.7 per cent in their fifth-straight advance on concerns about Middle East supply disruptions.

The biggest industry laggard was utilities, down 2.3 per cent, followed by communications services, which was under pressure from Alphabet's 2.5 per cent drop.

The benchmark S&P 500's biggest drag from a single stock was from Apple, after Jefferies assumed coverage with a "hold" rating, sending the stock down 2.3 per cent. Amazon.com finished down 3.0 per cent after a Wells Fargo downgrade.

Among the benchmark's biggest gainers was Generac Holdings , which added 8.52 per cent as investors bet on solid demand for backup power generators because of the pending hurricane.

Shares of Pfizer rose 2.0 per cent after a report that activist investor Starboard Value has taken a roughly $US1 billion ($A1.5 billion) stake in the drugmaker.

Air Products and Chemicals closed up 9.5 per cent on a report that activist hedge fund Mantle Ridge has built a position in the company.
