Piper Jaffray analyst James Fish upgraded F5 Networks to Neutral from Underweight and raised his price target for the shares to $163 from $157. After underperforming the tech sector and the market over the last six months by ~20%, some of the main downside share catalysts have played out, Fish tells investors in a research note. And while it carries execution risk and appears defensive, the acquisition of Nginx is the right strategic move, adds the analyst. Fish, however, remains concerned around some of the long-term risks facing F5, such as the software transition and competition.
