Coherent Corp. (NYSE:COHR) jumps 41% over the week as China optics restrictions coincide with earnings report

Coherent Corp. (NYSE:COHR) saw its stock jump 41% over the past week, driven by a proposed U.S. restriction on Chinese optical transceiver imports and strong investor anticipation ahead of its August 12 earnings report. This policy shift is viewed as "directionally bullish" for Coherent, as Chinese suppliers currently hold a significant market share. The company's equity value has climbed by approximately $21 billion since July 31, reflecting expectations of increased market share and strong fiscal Q4 results, particularly in its AI optics-driven Datacenter and Communications segment.
