Stocks inched higher in quiet trade Monday as empty economic and earnings calendars provided little impetus for the market. The Nasdaq added 0.3% as Baidu's (BIDU) 3% gain helped offset a 1% loss from Apple (AAPL) and Priceline.com's (PCLN) 4% slip. The Dow Jones industrial average chugged ahead 0.2% and the S&P 500 managed a fractional gain. Volume tracked 22% lower on the Nasdaq and down 4% on the NYSE compared with the same time Friday.
