US stocks rise but biggest gains fade as market stays volatile
US stock indexes finished slightly higher on Monday as investors let go of some of their fears about a possible trade war with China, although bigger gains slipped away as the market suffered a steep afternoon decline.
Stocks climbed higher in the first hours of trading and, at about 2pm, the Dow Jones industrial average was up 440 points.
That put the market on track to make up almost all of the ground it lost during a big sell-off on Friday.
However, stocks have repeatedly changed course as investors tried to guess the outcome of the US-China trade dispute and they did it again Monday afternoon.
Health care companies finished with strong gains and technology companies like Microsoft and Apple regained some of their recent losses. Banks rose along with interest rates.
However, industrial and retail companies finished with losses, and smaller firms fared worse than larger ones.
Marina Severinovsky, an investment strategist at Schroders, said stocks have done well recently when investors have got their minds off the trade disputes because the global economy and the US economy are still growing.
The S&P 500 index gained 8.69 points, or 0.3%, to 2,613.16. The S&P 500 fell 1.4% last week, with large losses on Monday and Friday, and strong gains in between.
The Dow Jones industrial average rose 46.34 points, or 0.2%, to 23,979.10. The Nasdaq composite jumped 35.23 points, or 0.5%, to 6,950.34. The Russell 2000 index of smaller company stocks added 1.17 points, or 0.1%, to 1,514.46.
Most of the stocks on the New York Stock Exchange finished lower on Monday.
