Coherent (COHR) is one of the explicitly named photonics companies in the list 'if you are interested in AAOI, GLW... COHR...' and the article's thesis is that photonics stocks are now attractive after a dump. Risk: Oversupply concerns flagged by the author's ongoing report could limit near-term upside.
COHR
