NEW YORK, Sept 28— Wall Street sank deeper into a bear market yesterday, with the S&P 500 recording its lowest close in almost two-years as Federal Reserve policymakers showed an appetite for more interest rate hikes, even at the risk of throwing the economy into a downturn.

The benchmark S&P 500 .SPX is down about 24 per cent from its record high close on January 3. Last week, the Fed signaled that high rates could last through 2023, and the index erased the last of its gains from a summer rally and recorded its lowest close since November 2020.

The S&P 500 has declined for six straight sessions, its longest losing streak since February 2020.

Speaking yesterday, St. Louis Fed President James Bullard made a case for more rate hikes, while Chicago Fed President Charles Evans said the central bank will need to raise rates by at least another percentage point this year.

"It’s disappointing, but it’s not a surprise,” said Robert Pavlik, senior portfolio manager at Dakota Wealth in Fairfield, Connecticut. "People are concerned about the Federal Reserve, the direction of interest rates, the health of the economy.”

Analysts at Wells Fargo now see the US central bank taking its target range for the Fed funds rate to between 4.75 per cent and 5.00 per cent by the first quarter of 2023.

Seven of 11 S&P 500 sector indexes fell, with utilities .SPLRCU and consumer staples .SPLRCS each down about 1.7 per cent and leading declines.

The energy sector index rallied 1.2 per cent after Sweden launched a probe into possible sabotage after major leaks in two Russian pipelines that spewed gas into the Baltic Sea.

Tesla gained 2.5 per cent and Nvidia NVDA.O added 1.5 per cent, with both companies helping keep Nasdaq in positive territory.

Traders exchanged over US$17 billion worth of Tesla shares, more than any other stock.

The Dow Jones Industrial Average fell 0.43 per cent to end at 29,134.99 points, while the S&P 500 .SPX lost 0.21 per cent to 3,647.29.

The Nasdaq Composite climbed 0.25 per cent to 10,829.50.

Concerns about corporate profits taking a hit from soaring prices and a weaker economy have also roiled Wall Street in the past two weeks.

Analysts have cut their S&P 500 earnings expectations for the third and fourth quarters, as well as for the full year. For the third quarter, analysts now see S&P 500 earnings per share rising 4.6 per cent year-over-year, compared with 11.1 per cent growth expected at the start of July.

Volume on US exchanges was 11.7 billion shares, compared with an 11.3 billion average for the full session over the last 20 trading days.

Declining issues outnumbered advancing ones on the NYSE by a 1.25-to-1 ratio; on Nasdaq, a 1.03-to-1 ratio favoured advancers.

The S&P 500 posted no new 52-week highs and 146 new lows; the Nasdaq Composite recorded 28 new highs and 502 new lows. — Reuters
