Macy's Inc could see its shares rise by 50 percent in a potential sale, as the struggling retailer looks to turn around its business by downsizing its physical-store operations and reinvesting in its online presence, Barron's said on Sunday. The Cincinnati-based company, which in recent years has become the sixth-largest online retailer, is a bargain for investors despite Wall Street's gloomy outlook with management's plans to close 100 underperforming stores, which could increase its stock by 20 to 30 percent. A potential sale, particularly one with a spinoff of the company's real estate assets, could boost Macy's stock to $45 to $50, the report added.
