Summit Research analyst Srini Nandury downgraded NetApp (NTAP) to Sell saying dynamics in the storage industry as well as the company's Cluster ONTAP product transition will make revenue growth "elusive in the near-term." Weaker storage spending and continued problems with getting customers to upgrade to Cluster ONTAP could drive consensus estimates lower from current levels, Nandury tells investors in a research note. Further, the analyst believes NetApp continues to lose high sales performers to competitors such as Nimble Storage (NMBL), Pure Storage, Tegile and Tintri. He expects the company's FY16 revenue to decline 6% on top of the 3% decline in FY15, with only modest growth in FY17. Nandury cut his price target for NetApp shares to $28 from $32. The stock closed Friday up 13c to $30.75.
