NEW YORK—Stocks had a mixed day Friday, as investors waited for negotiators to finish their work on a solution to Greece’s debt problems. Chinese stocks plunged 7 percent as fears spread that a yearlong bull rally there has become overheated. China’s benchmark index is still up more than double over the past year.
The Dow Jones industrial average added 56.32 points, or 0.3 percent, to 17,946.68. It was largely lifted by Nike, which rose more than 4 percent after posting strong quarterly results.
The Standard & Poor’s 500 index fell 0.82 of a point, or 0.04 percent, to 2,101.49 and the Nasdaq composite lost 31.68 points, or 0.6 percent, to 5,080.51. All three indexes ended the week slightly lower.
