Nordstrom shares closed down 3 percent Friday after analysts at Evercore ISI downgraded the stock to "sell" from "hold" and slashed their price target.

In a Friday note to clients, Evercore said: "We believe department stores have been over allocating capital and resources to support aggressive digital and off-price strategies for years, moving the industry away from its core competencies and advantages into new competitive situations that are unwinnable."
