NEW YORK, Dec 29 (Reuters) - U.S. stocks edged higher in a thinly-traded session on Monday as the market's recent upward bias continued and put the Dow on track for an eighth straight daily advance.
Equities have trended to the upside of late, with the S&P 500 up 5.9 percent over the past seven sessions, ending at its 52nd record close of the year on Friday. The Dow's seven-session streak is its longest since March 2013.
