US stock market news: Dow Jones manages 80-point rise but tech stocks-heavy Nasdaq slides amid recession fear

US stock market news: The S&P 500 dipped and the Nasdaq ended sharply lower on Wednesday after a growing wave of weak economic data deepened worries that the Federal Reserve's rapid interest rate hikes might tip the U.S. economy into a recession.

Nvidia Corp (NVDA.O) dropped 2.1 per cent and was among the stocks weighing most on the S&P 500 after Alphabet Inc's (GOOGL.O) Google unit said the supercomputers it uses to train its artificial intelligence models were faster and more power-efficient than comparable components made by the chipmaker.

Tesla Inc (TSLA.O) fell 3.7 per cent, while Amazon (AMZN.O) and Apple (AAPL.O) declined more than 1 per cent, pulling down the Nasdaq and reversing gains in some of Wall Street's most valuable companies in recent weeks.

Caterpillar (CAT.N), viewed as a bellwether for the industrial sector, dropped 1.8 per cent, bringing its loss over the past two days to 7 per cent as investors fretted about a potential economic downturn.

The S&P 500 declined 0.25 per cent to end the session at 4,090.38 points. The Nasdaq fell 1.07 per cent to 11,996.86 points, while the Dow Jones Industrial Average rose 0.24 per cent to 33,482.72 points.

Driving the recession fears, the ADP National Employment report showed U.S. private employers hired far fewer workers than expected in March. That followed Tuesday's weak job openings data.

Earlier this week data showed falling factory orders and soft manufacturing activity.

Wall Street's recent losses in reaction to signs of a slowing economy mark a change from recent months, when investors cheered weak economic data on the basis that it might mean the Fed's interest rate hikes were working and that the Fed could ease up on its campaign to rein in decades-high inflation.

Among stocks that kept the Dow Jones Industrial Average in positive territory, Johnson & Johnson <JNJ.N> rallied 4.5 per cent after its $8.9 billion offer to settle talc-related lawsuits gained the support of thousands of claimants, easing an overhang on its plans to list consumer health unit Kenvue.

FedEx Corp (FDX.N) rose 1.5 per cent as the freight bellwether firm said it will fold its operating divisions into one organization as it steps up efforts to cut costs and increase efficiency.
