NEW YORK (Reuters) -The Dow ended lower and the S&P 500 finished flat on Wednesday after the Federal Reserve cut interest rates but Fed Chair Jerome Powell said another rate cut in December is far from assured.

The Nasdaq registered another record closing high, boosted by Nvidia after the AI chipmaker made history as the first company to reach $5 trillion in market value.

In earlier trading, stocks rose and then added to gains after the Fed cut interest rates by a quarter of a percentage point, as expected, and said it will restart limited purchases of Treasury securities.

Fed policymakers also noted the limits in their decision-making process due to the U.S. federal government shutdown. The Fed lowered the overnight benchmark rate to a target range of 3.75% to 4.00%, the second time the U.S. central bank eased this year.

After Powell spoke, traders pared bets on a December rate cut, giving it a 71% chance, down from 90%.

"Chairman Powell indicated that another rate cut is not a foregone conclusion," said Oliver Pursche, senior vice president and advisor for Wealthspire Advisors in Westport, Connecticut.

"But no rate cut is ever a foregone conclusion. So, to me, that is not an inappropriate comment. The (Fed) is data dependent."

Nvidia's stock ended the session up 3% at $207.04, giving it a stock market value of $5.03 trillion. It has risen more than 50% this year, leading the artificial intelligence rally on Wall Street.

The Dow Jones Industrial Average fell 74.37 points, or 0.16%, to 47,632.00, the S&P 500 lost 0.30 points to 6,890.59 and the Nasdaq Composite gained 130.98 points, or 0.55%, to 23,958.47.

"The rate cut was expected. Powell’s remarks took some shine off the market," said Michael Rosen, chief investment officer at Angeles Investments in Santa Monica, California. "But this is a temporary reaction. It is earnings that ultimately drive equities, and those earnings have been strong."

The majority of U.S. earnings results so far this reporting period have beaten analysts' expectations. Of the 222 companies in the S&P 500 that have reported so far, some 84.2% have posted earnings above Wall Street estimates, according to data compiled by LSEG as of Wednesday. That is above the 77% average from the past four quarters.

Among Wednesday's key results, Caterpillar reported a third-quarter profit that beat expectations, and its shares jumped 11.6%.

After the closing bell, shares of Meta Platforms, Microsoft and Alphabet were mixed following quarterly reports by the three megacaps.

Shares of Meta Platforms were down more than 8% in extended trading, while Microsoft was down 1% and Alphabet was up about 5%.

Meta recorded a nearly $16 billion one-time charge that hurt third-quarter profits and said its capital expenditure next year would be "notably larger" than in 2025.

Strong AI demand helped Alphabet's financial results, while Microsoft's AI infrastructure spending soared to a record in the September quarter and deepened investor cost concerns.

Declining issues outnumbered advancers by a 2.16-to-1 ratio on the NYSE. There were 476 new highs and 170 new lows on the NYSE.

On the Nasdaq, 1,453 stocks rose and 3,306 fell as declining issues outnumbered advancers by a 2.28-to-1 ratio.

Volume on U.S. exchanges was 20.71 billion shares, compared with the 21 billion average for the full session over the last 20 trading days.
