On August 6, Coherent fell 3.1% in pre-market trading, trading at $318.42/share, with turnover of $13.15 million.

The decline reflects short-term profit-taking pressure after the stock surged over 15% since August 4, when the U.S. Federal Communications Commission reportedly began drafting measures to ban imports of new Chinese optical transceiver modules to protect AI data center critical infrastructure. That policy catalyst drove Coherent up nearly 12% on August 4 alone, with gains extending on August 5. The rapid accumulation of unrealized gains has now triggered selling pressure.

Sector peer Corning declined 2.44%, with the broader Electronic Components sector trading weak. Coherent is scheduled to report fourth fiscal quarter earnings on August 12, with consensus expecting revenue of approximately $19.86 billion, up 31.65% year-over-year, and adjusted EPS of approximately $1.62, up 76.71% year-over-year. Institutional views remain broadly positive ahead of the release.
