COHH is trading at $5.82, with a -4.67% change in pre-market as rising rates pressure leveraged technology exposure. - Strong September PMI data lifted the 10-year Treasury yield above 5.1%, increasing expectations for another Federal Reserve hike and weighing on growth-stock valuations. - U.S. equity futures are lower, reinforcing the risk-off tone. - Coherentβs PhotonLink launch appears secondary to broader profit-taking and macro pressure as COHH extends its September 23 decline.
