As previously reported, Morgan Stanley analyst Meta Marshall downgraded Acacia Communications to Underweight, the firm’s equivalent of a sell rating, from Equal Weight. He thinks Wall Street estimates remain too high for 2019 as he does not see a rebound in Acacia’s biggest markets -namely China and datacomm systems – being as lucrative as consensus expectations given competition and pricing pressures, Marshall tells investors. Consensus expectations are for over 20% growth in 2019, and while this is “certainly possible,” Marshall thinks growth is likely to be “much more metered” next year, he added. The analyst lowered his price target on Acacia shares to $30 from $37.
