Video: J.C. Penney Reveals its Prototype Store

Shares of J.C. Penney were moving higher Tuesday after the retailer gave CNBC a tour of its new prototype store. Investors have expressed concern about the retailer since February when it said it would overhaul its pricing under new CEO Ron Johnson. The idea was to move customers away from the coupons and promotions that they've come to expect and simplify J.C. Penney's pricing structure. But Wall Street hasn't backed the idea yet, and investors have sent shares of J.C. Penney down almost 50 percent since February.
