The index on Monday inched past its most recent record-high close set on Friday, extending its gain for the year to 10.4 percent. The Dow Jones industrial average also ended higher after briefly eclipsing its most recent high. The Nasdaq composite ended lower.
The latest milestone for the S&P 500 came on a day when the major U.S. stock indexes mostly hovered between small gains and losses as investors weighed the implications of an economic slowdown in Japan that worsened in the third quarter into a recession. Energy stocks fell as the price of crude oil resumed its slide.
The major stock indexes started off in negative territory early Monday as the markets reacted to data showing the world’s third-largest economy unexpectedly shrank at a 1.6 percent annual pace in the third quarter after contracting 7.1 percent the previous quarter.
Tokyo’s benchmark Nikkei stock index lost 3 percent.
U.S. markets veered lower much of the morning. By afternoon, though, stocks began to pare some their losses as traders cheered several pieces of corporate deal news.
Shares in Botox-maker Allergan and oilfield services company Baker Hughes were among the biggest gainers.
In the end, the S&P rose 1.50 points, or 0.1 percent, to 2,041.32. That’s just ahead of its previous all-time high close of 2,039.82 on Friday.
The Dow gained 13.01 points, or 0.1 percent, to 17,647.75. The Nasdaq composite fell 17.54 points, or 0.4 percent, to 4,671.
The three major stock indexes are up for the year.
Stocks have been mostly rising since Oct. 15, when the S&P 500 nearly fell into a “correction,” a trading term for a drop of 10 percent or more from a recent peak.
Generally strong corporate earnings results and solid U.S. economic data have helped blunt the impact of global economic uncertainty.
Six of the 10 sectors in the S&P 500 ended lower, with energy stocks falling most. The sector is down 3.8 percent this year, and is the only one in the red for 2014. Utilities rose the most.
