Restoration Hardware—BB&T upgraded the luxury home furnishings retailer to "buy" from "hold," saying it's encouraged by the potential for the company's new "RH Modern" product line.
Target—BMO downgraded the retailer's shares to "market perform" from "outperform," citing uncertainty created by the move of chief merchandising officer Kathee Tesija into an advisory role.
Facebook, Amazon.com, Yahoo—Mizuho initiated coverage on the three stocks with "buy" ratings. It said Facebook has the highest profit margin profile of any online media company, and Amazon has expansion opportunities in high margin businesses like Amazon Web Services. The Yahoo rating is based on factors such as the taxation scenario for Yahoo's Alibaba shares, the company's net cash position, and other factors.
