Retailers are on analysts' minds today with bullish calls for Zulily and Walgreen but a cut for Coach. Goldman Sachs is upgrading the children's apparel company Zulily to a 'buy' rating from 'neutral' with a new 12-month price target of $50. Walgreen is upgraded by Jefferies to a 'buy.' The firm sees the drugstore giant's cost cutting initiatives as a positive for the stock and is also raising the price target to $87. But Bank of America Merrill Lynch downgrades Coach to an 'underperform.' The firm says Coach's "financial targets look unachievable." TheStreet's Susannah Lee has the details.
