NEW YORK, Aug 13 (Reuters) - U.S. stocks rose on Wednesday, with the Dow returning to positive territory for the year as the market shrugged off weak earnings reports and a slump in retail shares.
Retail stocks capped the market's gains as retail sales unexpectedly stalled in July, marking the weakest report since January. Macy's quarterly earnings missed analysts' estimates and the stock fell 6.4 percent to $55.96.
Despite data painting a weak consumer picture, all 10 S&P primary sectors gained. Biotech shares surged, with the Nasdaq biotech index climbing 2.1 percent on the back of stocks including InterMune Inc and Jazz Pharmaceuticals PLC .
