Take a look at some of Friday's morning movers:

J.C. Penney - The retailer reported a second quarter loss of $0.37 per share, wider than estimates of a $0.25 per share loss. Penney also says it won't achieve its previous 2012 earnings guidance. CEO Ron Johnson, however, says the company's transformation is on track, but warns that it will take time.

Ralph Lauren - The apparel maker has added an additional $500 million to its stock buyback program, on top of the $277 million in authorizations still available under a prior plan.

Nordstrom - Nordstrom earned $0.75 per share for the second quarter, a penny above estimates, with revenues essentially in line. The retailer did raise its profit and sales forecast for 2012, as results at its lower-priced Rack chain improve.

Nvidia - The company earned $0.27 per share for the second quarter, well above Street estimates of $0.14. The graphics chipmaker also gave current quarter revenue guidance that exceeds analyst forecast, on upbeat sales of its new graphics processor as well as its increasing share of the mobile chip market.
