On June 4, COHERENT fell 5.2% in regular trading, trading at $397.72/share, with trading volume of $202 million. The stock continued its pullback from recent highs as profit-taking pressure intensified following a sharp multi-day rally.

On the news front, COHERENT previously surged over 17% on June 2, hitting a 52-week high of $426.89, after NVIDIA announced a $2 billion strategic investment in the company for photonics technology R&D and U.S. domestic manufacturing expansion. The two companies signed a multi-year strategic agreement to secure key capacity in laser sources, optical devices, and silicon photonics. The broader optical communications sector experienced a full-scale rally that day, with Marvell Technology surging over 32% and Corning gaining over 13%.

Following consecutive sharp gains, profit-taking pressure has persisted. The stock declined 3.19% during regular trading on June 3, fell another 3.22% after hours to $403.99, and continued weakening in pre-market on June 4. Fundamentally, NVIDIA's strategic agreement remains in execution, 1.6T optical module demand continues to surge, and COHERENT has raised its small form-factor pluggable optical module shipment target to 5 million units.
