COHERENT CORP (COHR) is down -9.63% in the latest session. Our newswire has captured 4 stories on COHR across 4 sources in the last 36 hours, with AI sentiment reading bullish (avg 58/100).
Coherent Corp (COHR) shares fell 9.63% to $302.35 on Thursday. The decline followed a broader sector rotation where optical component makers were sold off after a year of extraordinary gains. Profit-taking pressure hit the group hardest, with peers Applied Optoelectronics and Lumentum also posting significant losses.
The sell-off occurred despite recent positive commentary regarding supply constraints. Lumentum Holdings CEO Michael Hurlston stated that optical parts are completely sold out through early 2029 due to AI data center demand. This supply tightness was highlighted in a report noting that the VCSEL market is projected to reach $1.96 billion by 2032, driven by AI and 3D sensing applications. Coherent is identified as a key player in this expanding market.
However, the stock’s valuation and recent price action triggered the pullback. The company’s shares had run furthest among its peers, making them a primary target for profit-taking. The broader market context included a slip in the S&P 500 and easing 10-year yields, which may have contributed to risk-off behavior in high-beta technology names.
Coherent trades with a market cap of $66.3 billion and a price-to-earnings ratio of 81.2. Trailing twelve-month revenue grew 22.5%, and the net margin stands at 11.3%. The stock carries a beta of 2.11, indicating high volatility relative to the market. The 52-week range spans from $108.19 to $440.00.
Insider activity has been predominantly negative over the last 90 days, with nine sales totaling $9.4 million and no buys. Recent Form 4 filings show sales by Director Enrico Digirolomo, Chief Strategy and Legal Officer Robert P. Beard, and Director Lisa Neal-Graves. Congressional disclosures in the same period recorded five sells and two buys, with the most recent filing dated October 8, 2026. On October 8, the stock printed seven fresh 52-week highs and 48 fresh 52-week lows, reflecting extreme intraday volatility.
Investors should monitor upcoming earnings reports and continued sector-wide profit-taking. The divergence between strong fundamental growth and high valuation multiples remains a key factor. Additionally, the impact of AI data center demand on optical component supply chains will be a critical driver for future price action.
