Updates after markets open

Dec 12 (Reuters) - The S&P 500 and the Nasdaq slipped on Thursday after ending the previous session on a positive note, while investors assessed some of the last economic datasets ahead of the Federal Reserve's meeting.

The Nasdaq soared past the 20,000 mark for the first time on Wednesday as the technology rally showed no signs of a halt, while the S&P 500 closed at its highest in nearly a week after an in-line inflation reading locked in a 25 basis point cut by the Fed at its Dec. 17-18 meeting.

Meanwhile, data showed U.S. producer prices rose more than expected in November amid a surge in the cost of food, but a moderation in the prices of services offered hope that the disinflationary trend remains in place.

"Those numbers are a little bit hotter than expectations and (are) on the heels of CPI," said Thomas Martin, senior portfolio manager at Globalt Investments.

"(The Fed) is going to (cut rates) because it wants to stay on that path and would like to have rates be lower, but there's this risk about inflation."

Separately, data showed the number of Americans filing new applications for unemployment benefits rose unexpectedly to 242,000 for the week ended Dec. 7, above estimates of 220,000.

Trader bets on the cut next week stand at over 98%, according to CME's FedWatch Tool. They had risen after a jobs report on Friday that showed unemployment rose last month despite a surge in jobs growth.

However, bets also indicate expectations of a pause in January after several Fed officials last week urged caution over the pace of monetary policy easing as the economy remained resilient.

At 9:37 a.m. ET, the Dow Jones Industrial Average .DJI rose 40.06 points, or 0.09%, to 44,188.62, the S&P 500 .SPX lost 15.55 points, or 0.26%, to 6,068.64 and the Nasdaq Composite .IXIC lost 95.17 points, or 0.48%, to 19,939.73.

Seven of the 11 major S&P sub-sectors were trading lower, with information technology .SPLRCT leading losses, down 0.6%.

Most megacap and growth stocks trended lower early on, with Nvidia NVDA.O down over 1%.

Wall Street's main indexes have set new record highs multiple times this year, thanks to a rally driven by heavyweight tech stocks that have exploited the euphoria around artificial intelligence and the Fed's interest rate cuts.

U.S. equities capped off a remarkable November after Donald Trump's victory in the presidential election on the prospects of business-friendly policies adding to corporate profits, and have kicked off December on a broadly positive note.

Among significant movers, Adobe ADBE.O slid 11.2% after the Photoshop maker forecast fiscal 2025 revenue below Wall Street expectations on Wednesday.

Nordson NDSN.O lost 3.6% as the dispensing equipment maker forecast fiscal 2025 revenue below Wall Street estimates.

Centene CNC.N gained 1.4% following the health insurer's forecast of its 2025 profit above estimates.

Declining issues outnumbered advancers by a 1.62-to-1 ratio on the NYSE and by a 1.4-to-1 ratio on the Nasdaq.

The S&P 500 posted five new 52-week highs and three new lows, while the Nasdaq Composite recorded 23 new highs and 44 new lows.
