After reviewing historical market share data, Sterne Agee CRT says that Pandora (P) has dropped about 16% since May 29, and the firm blames the slide on worries about new streaming music offerings from Apple (AAPL) and Google (GOOG). The firm believes that worries about the threat to Pandora from Apple's and Google's streaming music offerings are overdone. It says that Apple Music's lack of a free service and the absence of interactive features in Google's offering and Beats should limit the negative impact of those services on Pandora. Sterne Agee CRT keeps a $22 price target and Buy rating on Pandora.
