Another tough day for the retail sector left the Dow and S&P500 with small losses on Friday and saw both indices snap a 3-week winning streak - Dow eased -23-points or -0.11% (to be -0.52% lower for the week) and the broader S&P500 -0.15% (for a weekly decline of -0.35%). The technology-centric NASDAQ inched +0.09% higher and posted its fourth consecutive weekly gain (adding +0.34%). In stock-specific news, J.C. Penney and Nordstrom tumbled after disappointing first-quarter results to cap a tough week for the retail sector (after both Macy's and Kohl's also disappointed the market with their quarterly numbers earlier in the week).
