On October 9, Coherent rose 5.5% in regular trading, trading at $323.965/share, with Turnover of $2.12 billion.

The rebound was driven by a technical recovery in the optical communications sector after two consecutive days of profit-taking, further fueled by news that Lumentum's optical component orders extend to 2029.

Earlier during the session, the broader optical communications group staged a collective rally, with Lumentum and Applied Optoelectronics rising more than 6%, Corning and Ciena advancing over 3%, and Coherent building on its pre-market and overnight gains. Morgan Stanley, however, cautioned that short-term sector catalysts ahead of the OCP conference may be largely priced in, reflecting a balanced view relative to the immediate rebound.
