The Dow Jones industrial average rose 53.95, or 0.5 percent, to 10,820.28, its highest close since March 10. The advance also put the Dow into positive territory for the year.

The S&P 500 added 6.58, or 0.53 percent, to 1254.85, and the Nasdaq gained 14.60, or 0.66 percent, to 2241.67.

Meanwhile, forecasters said a nearing snowstorm could hit several northeastern states by midweek, pushing crude oil higher on renewed supply concerns.
