01:30 PM EDT, 10/29/2025 (MT Newswires) -- US equity indexes scaled new peaks in midday trading on Wednesday, as technology topped sector charts ahead of a widely anticipated easing of monetary policy by the Federal Reserve and Nvidia ( NVDA ) hit a record $5 trillion in market capitalization.

The Nasdaq Composite rose 0.6% to 23,974.43, after hitting a record 24,019.99 earlier in the session. The S&P 500 was up 0.3% to 6,909.44, also scaling a new peak of 6,920.34 intraday. The Dow Jones Industrial Average climbed 0.5% to 47,927.47, after posting an all-time high of 48,040.64 intraday.

The Fed is widely expected to cut interest rates by 25 basis points, according to the CME FedWatch Tool. Investors will also look out for Fed Chair Jerome Powell's comments on the path ahead for policy in a press briefing following the policy announcement. Currently, the probability of another rate reduction of the same magnitude in December is 85%.

"Tonal balancing is likely to be conveyed in Jay Powell's press conference, which may sound 'hawkish' to listeners that have been inculcated into the narrative of a Fed that is prepared to cut aggressively well into 2026," Macquarie said in a note.

"Of course, the FOMC Statement and press conference are likely to touch upon low turnover in the US labor market, 'sticky' inflation, and the implicit tension in fulfilling the Fed's dual mandate due to this whiff of stagflation," the note added.

Treasury yields were mixed, with the 10-year yield up 1.6 basis points to 4%.

Meanwhile, Nvidia's ( NVDA ) shares rose 2.8%, building on the previous day's momentum amid media reports that President Donald Trump could discuss the firm's Blackwell artificial intelligence chip with his Chinese counterpart, Xi Jinping, during the duo's meeting on Thursday.
