U.S. equities resumed their winning ways last week, halting a shallow two-week skid. The S&P 500 rose 0.9 percent during the holiday shortened week and closed above 2600 for the first time. Technology stocks once again drove most the gain. The sector added 1.8 percent on the week, and for the year has more than doubled the 16 percent rise in the overall index. Industrials, materials and consumer discretionary stocks also rose more than the overall index for the week.
