(Reuters) -The S&P 500 and the Dow fell on Monday in holiday-thinned trading after a stopgap government funding bill averted a U.S. government shutdown and investors braced for a slower pace of rate cuts from the Federal Reserve next year.

After a solid run since the November presidential election, Wall Street's rally hit a bump this month, especially after the U.S. Federal Reserve forecast just two 25-basis-point rate reductions for 2025 - down from its September view of four cuts - and raised its annual inflation outlook.

A cooler-than-expected inflation report on Friday helped U.S. stocks recoup some losses. However, overall market sentiment was still cautious, said Thierry Wizman, strategist at Macquarie.

Money markets expect roughly two 25-bps reductions in 2025, which would bring the benchmark rate to a range of 3.75% to 4.0%, from about a 3.50% to 3.75% range two weeks ago.

"It's a Monday with very few catalysts to drive (broad market) sentiment, and we're going to have low volume, likely volatile trading as we work our way out of this year," said Art Hogan, chief market strategist, B Riley Wealth.

Trading volumes are expected to thin, with U.S. stock markets closing early on Tuesday and shut for Christmas on Wednesday.

At 11:07 a.m. the Dow Jones Industrial Average fell 247.19 points, or 0.58%, to 42,593.07 and the S&P 500 lost 5.47 points, or 0.09%, to 5,925.38.

Since 1969, the last five trading days of the year, combined with the first two of the following year, have yielded an average S&P 500 gain of 1.3% - a period known as the "Santa Claus Rally", according to the Stock Trader's Almanac.
