U.S. stocks rose, with the Standard & Poor’s 500 Index posting its strongest weekly gain this year, as equities continued to rebound from their worst quarter since 2011.

Shares advanced Friday without the help of energy and raw-material companies, the two best-performing groups so far this month, as energy snapped its longest winning streak in six years. Apple Inc. added 2.4 percent to boost technology shares. Alcoa slumped 6.8 percent to weigh on commodity related companies.

The S&P 500 added 0.1 percent to 2,014.97 at 4 p.m. in New York, up 3.3 percent for the week, the most since December. A measure of volatility extended a streak of declines to the longest in four years.

Energy companies in the benchmark index fell after yesterday stretching an advance to an eighth day, the longest in six years. The group is poised for the best weekly climb in 2015, up more than 7.5 percent. Materials and industrials marked their strongest week since December 2011.
