Feb 26 (Reuters) - The tech-heavy Nasdaq led Wall

Street's main indexes higher on Wednesday as chip stocks

rebounded ahead of Nvidia's ( NVDA ) results that are crucial to

illuminating future demand for AI.

At 11:31 a.m. ET, the Dow Jones Industrial Average

rose 122.51 points, or 0.28%, to 43,743.67, the S&P 500

gained 42.56 points, or 0.71%, to 5,997.81 and the Nasdaq

Composite gained 211.83 points, or 1.11%, to 19,238.21.

Eight of the S&P 500's 11 sectors traded higher, with

technology stocks rising 1.8%.

AI chip leader Nvidia ( NVDA ) gained 4.4%, while peers

Broadcom ( AVGO ) and Advanced Micro Devices ( AMD ) also rose,

driving the broader semiconductor index 2.6% higher.

Nvidia's ( NVDA ) quarterly results and forecasts, expected after

markets close, are likely to set the tone for artificial

intelligence stocks that have dominated Wall Street.

The launch of low-cost AI models from China's DeepSeek had

rattled the industry in January and raised questions around Big

Tech's heavy investments into the technology.

"(Nvidia's ( NVDA )) been the bellwether of this bull market... but

(what's) fundamentally shifted is this assumption that the only

companies that will win and dominate generative AI themes are

the 'Magnificent Seven'," said Lisa Shalett, chief investment

officer at Morgan Stanley Wealth Management.

"What the DeepSeek news reminds everybody is, that's not how

technology revolutions work."

Megacaps were mixed, with Meta Platforms ( META ) up 3%

and Apple ( AAPL ) down 2%. Tesla rose 1.2% a day after

the electric-vehicle maker's market value fell below $1

trillion.

Super Micro jumped 19.6% after the chip company

filed long-delayed annual and quarterly reports.

Since last week, a series of data releases, including

Tuesday's weak consumer sentiment print, has hinted that the

world's largest economy might be stalling despite inflation

remaining high, keeping investors on the edge.

The S&P 500 and the Nasdaq logged their biggest four-day

declines since September on Tuesday, also due to weakness in

tech stocks, after an analyst report hinted at overcapacity in

AI infrastructure.

Wall Street's main indexes were also on track for monthly

declines, with the Nasdaq poised for its worst drop in ten

months.

However, a Reuters poll showed strategists still expect the

S&P 500 to finish 2025 about 9% higher than current levels,

although market volatility will persist.

On the fiscal front, President Donald Trump's $4.5 trillion

tax-cut and border security agenda will be sent to the U.S.

Senate after passing the Republican-controlled House of

Representatives.

Traders expect the Fed to deliver its first interest rate

cut in July, according to data compiled by LSEG.

In the latest on global trade, Trump ordered a probe into

potential new tariffs on copper imports, sending prices of the

red metal higher. Phoenix-based copper miner Freeport-McMoran ( FCX )

jumped 5.2%.

General Motors ( GM ) rose 5.4% as the automaker said it

would increase its quarterly dividend by 25% and undertake a new

$6 billion share buyback program.

Intuit shares rose 13.3% after the TurboTax maker

forecast third-quarter revenue above Street estimates.

Advancing issues outnumbered decliners by a 2.01-to-1 ratio

on the NYSE and by a 2.06-to-1 ratio on the Nasdaq.

The S&P 500 posted 17 new 52-week highs and one new low

while the Nasdaq Composite recorded 30 new highs and 110 new

lows.
