Piper Jaffray analyst Troy Jensen upgraded Finisar (FNSR) to Overweight from Neutral and raised his price target for the shares to $26 from $18. The shares closed yesterday down 95c, of 5%, to $18.65. China demand is returning via Huawei and ZTE (ZTCOY), Finisar is facing easy comps following five quarters of depressed demand and the upcoming 400G cycle should provide a tailwind in 2019, Jensen tells investors in a research note. On top of improving optical industry dynamics, the analyst believes Finisar's new CEO will improve the cost structure and execution at the company and drive better profitability. Now is a "great time" to revisit owning the shares, Jensen contends. The analyst this morning also upgraded Acacia Communications (ACIA) to Overweight from Neutral.
