Stocks closed mixed Friday after a half-day trading session capped a holiday shortened week. The S&P 500 inched up 0.1% after wavering between small gains and losses much of the day. The Dow Jones Industrial Average added 0.3% and the Nasdaq composite slipped 0.1%. The indexes notched their fourth straight winning week. Trading was muted as markets reopened following the Thanksgiving holiday on Thursday. Gains in health care, financial, energy and other sectors helped temper losses in technology and communication services stocks.
