Stock indexes closed mostly lower Tuesday as the market delivered a downbeat finish on the final day of another milestone-shattering year on Wall Street. The S&P 500 gave up an early gain to finish down 0.

NEW YORK — U.S. stocks closed broadly lower Monday as a banner year on Wall Street looked set to finish on a sour note. The S&P 500 fell 1.1%, its third straight decline. Roughly 90% of stocks within the index lost ground. On the second-to-last day of 2024, the benchmark index was still on track for its second straight yearly gain of more than 20%.

The market outlook for 2025 sees U.S. GDP growing at a healthy rate, the stock market gains diversifying beyond the Magnificent Seven—with health care a likely winner—and an evolution in the AI sector that powered virtually all of last year’s rally.
