B. Riley FBR analyst Dave Kang lowered his price target for Lumentum (LITE) to $68 from $74 and for Inphi (IPHI) to $45 from $47. While the ban on Huawei has garnered investor attention recently, the bigger issue for the optical industry could be China's internalization of its supply chain, which has been accelerated due to the recent ban, Kang tells investors in a research note. The analyst believes that even after the partial reprieve on Huawei, the U.S. optical companies may not fully recover to the previous levels with Huawei. Recent channel checks revealed that Huawei has significantly accelerated the internalization process of its supply chain, adds the analyst. As a result, he believes the U.S. optical industry is facing "collateral damage" from the trade war with China. Kang keeps a Buy rating on Lumentum and Neutral rating on Inphi. He favors Huawei's competitors such as Ciena (CIEN) and Dasan Zhone Solutions (DZSI), which he believes could gain market share from international customers diversifying away from Huawei.
