- J.C. Penney's stock performance declined during Ron Johnson's tenure as CEO from November 2011 to March 2013, with its performance falling behind competitors like Macy's and becoming similar to struggling retailer Sears. - The company experienced a decrease in sales, reduction of assets, and increased losses during this period. - Johnson's strategic changes to eliminate sales and coupons alienated JC Penney's traditional customer base without attracting new customers. His lack of presence at the company's Texas headquarters also hurt employee morale.
