Sept 10 (Reuters) - The S&P 500 and Nasdaq notched record-high closes on Wednesday, as Oracle surged and cooler-than-expected inflation data supported expectations the U.S. Federal Reserve will cut interest rates next week.
Oracle (ORCL.N), soared 36% in its biggest one-day percentage gain since 1992 after the tech company pointed to a demand surge from AI firms for its cloud services.
Its stock market value reached $922 billion, leapfrogging the values of Eli Lilly (LLY.N), JPMorgan Chase (JPM.N), and Walmart (WMT.N), and approaching Tesla's (TSLA.O), $1.12 trillion market value.
Artificial intelligence-related chip stocks also rallied, with Nvidia (NVDA.O), up 3.8%, Broadcom (AVGO.O), jumping 10% and Advanced Micro Devices (AMD.O), climbing 2.4%. The PHLX chip index (.SOX), rose 2.3% to a record high.
Data center power suppliers also benefited, with Constellation Energy (CEG.O), Vistra (VST.N), and GE Vernova (GEV.N), all rising more than 6%.
Apple (AAPL.O), viewed by many investors as lagging in the race to dominate AI, declined 3.2%, sliding for a fourth straight session.
A cooler-than-expected producer prices reading provided additional momentum as traders shored up their bets on interest-rate cuts this year.
Recent labor market data has confirmed the U.S. jobs market is in a slowdown.
Traders fully expect the Fed to cut interest rates by at least 25 basis points at its policy meeting next week, with a 10% chance the central bank could cut by 50 basis points, CME's FedWatch tool showed.
The S&P 500 has now climbed about 11% in 2025, while the Nasdaq has rallied about 13%.
"The fundamentals remain very strong in the equity markets, domestically. But we also have to acknowledge that valuations are extended at this point and serve as some natural tension to a continued upward trajectory," said Bill Northey, senior investment director at U.S. Bank Wealth Management in Billings, Montana.
The S&P 500 climbed 0.30% to end the session at 6,532.04 points, closing with a record high for the second straight day.
The Nasdaq gained 0.03% to 21,886.06 points for its third consecutive record-high close. The Dow Jones Industrial Average declined 0.48% to 45,490.92 points.
Six of the 11 S&P 500 sector indexes declined, led lower by consumer discretionary (.SPLRCD), down 1.58%, followed by a 1.06% loss in consumer staples (.SPLRCS).
Investors will now focus on consumer prices data due on Thursday, for insights on where U.S. inflation is headed.
"Combining the softer data (PPI figures) with the Fed's increased emphasis on the labor market side and the growing trend we've seen in downward revisions to the monthly employment data - all support the expectation for a rate cut," said Jordan Rizzuto, CIO at GammaRoad Capital Partners.
In a setback for the White House, a federal judge on Tuesday temporarily blocked U.S. President Donald Trump from removing Fed Governor Lisa Cook.

Declining stocks outnumbered rising ones within the S&P 500 (.AD.SPX), by a 1.5-to-one ratio.
