Ackman Exits and Leaves Puzzlement

``When somebody like Carl Icahn sets his sights on, say, Motorola, you may not agree with his methods, but you can’t deny he has taken aim at a seriously troubled company. But Target? In July 2007, when Mr. Ackman began buying the stock, the shares were trading in the 60s, near the all-time high. More to the point, Target isn’t exactly a troubled company. Rather, it is just about the only big-box retailer that has figured out how to compete successfully against Wal-Mart. Its 10-year stock performance is better than Wal-Mart’s. Analysts swoon over it. Customers, 80 percent of them women, love it.''
