U.S. stocks closed higher on Wednesday, with each of the major indexes recording their fifth straight session of gains as the Dow Industrials and S&P 500 registered closing record highs in a broad rally during a holiday-shortened session.

Indexes have been climbing in recent days, buoyed in part by a rebound in AI-related names after last week's selloff that was triggered by concerns ‍about inflated valuations and high capital expenditures denting profits.

But recent data showed the economy remains resilient, and the market ‍is still pricing in roughly 50 basis points of rate cuts from the Federal Reserve next year, although expectations for a January cut are low, according to CME's FedWatch Tool. Data on Wednesday showed ⁠new applications for U.S. jobless benefits unexpectedly fell last week.

Trading volumes were thin. The U.S. markets will remain shut on Thursday for Christmas.

"Yields are behaving, volume is light, but the same issues remain in place - AI is strong, there is talk ​of some positives here, new OpenAI and Meta models, that will get the chatter up," said Tim Ghriskey, senior portfolio strategist at Ingalls & Snyder in New York.

"The Fed is unlikely to lower rates again, at least for a while. Who knows what happens when May comes and we get a new head ‍of the Fed? But we have a very low probability of a January cut."

According to preliminary data, the S&P 500 gained 22.33 points, ⁠or 0.32%, to end at 6,932.12 points, while the Nasdaq Composite gained 51.46 points, or 0.22%, to 23,613.31. The Dow Jones Industrial Average rose 289.40 points, or 0.60%, to 48,731.81.

Micron Technology shares jumped, extending their rally after the company issued a strong forecast last week. Bank stocks also supported gains, and financials were among the best performing of the 11 S&P 500 sectors.

Recent gains in U.S. stocks have spurred hopes of ⁠a "Santa Claus rally," a seasonal phenomenon where the S&P 500 ​posts gains in the last five trading ⁠days of the year and the first two in January, according to Stock Trader's Almanac.

That period began on Wednesday and would run through January 5.

U.S. equities have swung sharply ‍this year as tariff-related headlines, concerns about high valuations in technology and AI companies, and rapidly shifting interest-rate expectations boosted volatility.

Wall Street's "fear gauge" was holding at levels not seen since December ‌2024. Still, the bull market, which began in October 2022, stayed intact as optimism around AI, rate cuts and a resilient economy supported sentiment, with all three main indexes set for their third straight yearly gain.

In the year ahead, global markets will be closely watching potential successors ⁠to Fed ​Chair Jerome Powell, after President Donald Trump said ‍on Tuesday that anyone who disagrees with him would "never be the Fed chairman."

Nike climbed after Apple CEO Tim Cook, the sportswear giant's lead independent director, bought about $3 million of shares. Intel fell following a report that Nvidia has halted tests ‍to manufacture Intel's 18A chipmaking node.

Dynavax Technologies surged after French drugmaker Sanofi said it would buy the U.S. vaccines company for around $2.2 billion (1.9 billion euros).
