EMMETT WARREN, NEWS EDITOR [email protected]Coherent Inc. (Nasdaq:COHR) saw its shares rise 10.3% over the last 30 days of 2019. The swift growth was due in part to new investments in the company’s manufacturing infrastructure as well as ongoing negotiations in international trade wars. Overall, Coherent shares increased by 64% over the calendar year. By the end of November, Coherent’s stocks were trading at $150.86 per share. By Dec. 31, the closing price was $166.35. Anders Bylund, a technology and entertainment specialist at The Motley Fool, said this spike in value could be attributed to a number of factors. ...Read full articleRelated content from Photonics MediaARTICLESBonati Appointed CTO and Head of R&D at FISBAGuido Bonati was appointed CTO and head of research and development at FISBA.
