Aug 14 (Reuters) - U.S. stocks inched higher on Friday afternoon after upbeat economic data and gains in retailer shares, though a decline in energy shares limited the move up.
J.C. Penney and Nordstrom both rose after the department store chains posted better-than-expected quarterly results. J.C. Penney was up 5.1 percent at $8.48 while Nordstrom jumped 3.7 percent to $77.72 and was among the biggest percentage gainers in the S&P 500, while the S&P retail index was up 0.4 percent.
