As previously reported, Wunderlich analyst Matthew Robison upgraded Nimble Storage to Buy from Hold in a post-earnings note to investors. Robison noted that Nimble shares have pulled back along with the broader market and due to waning speculation of Cisco (CSCO) acquiring the company, but said its deferred revenue and margin strength in the face of competitive pressure have improved its visibility. The analyst keeps his $33 price target on Nimble shares, which closed up 30c at $23.83 yesterday ahead of its earnings report, which was issued after the close.
