NEW YORK—The Dow and S&P 500 edged higher on Friday and ended a turbulent week with slight increases, helped by gains in Tesla and Facebook that offset a tumble by Nike.
Athletic wear company Nike’s shares fell 6.3 percent and were the biggest drag on the Dow and the S&P 500 after it delivered a downbeat sales forecast and warned of delays during the holiday shopping season, blaming a supply chain crunch.
