Light FQ3 guidance isn't stopping F5 (FFIV +5%) from rallying in the wake of its FQ2 report; expectations were depressed thanks to the April 4 warning. On F5's earnings call, management insisted enterprise demand is healthy ahead of a mid-range application delivery controller (ADC) refresh and an update to F5's TMOS OS, even as U.S. telco and federal demand remains weak. Strong momentum was also claimed for F5's firewall and 4G infrastructure offerings. Nomura has upgraded shares to Buy, arguing "the market may be overstating the competitive risks to F5" from Citrix (CTXS - previous). Up in sympathy: RDWR +4%. RVBD +4.8%.
