What Happened?
Shares of materials and photonics company Coherent (NYSE: COHR) jumped 8.8% in the afternoon session after a strong earnings report and positive outlook from rival Lumentum Holdings boosted sentiment for the optical networking equipment sector. Lumentum, a key player in the photonics industry, delivered fiscal fourth-quarter revenue and earnings that surpassed Wall Street's forecasts and issued a stronger-than-expected sales forecast for the upcoming quarter.
The upbeat results reinforced expectations of robust demand for optical networking equipment, lifting shares of peers across the space. The positive signal encouraged investors ahead of Coherent's own fiscal fourth-quarter results, which were scheduled for release after the market close on the same day. Analysts expected Coherent to report significant growth, fueled by surging demand for optical components used in artificial intelligence data centers.

What Is The Market Telling Us
Coherent’s shares are extremely volatile and have had 72 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The biggest move we wrote about over the last year was 12 months ago when the stock dropped 23.2% on the news that the company issued disappointing revenue guidance for its upcoming third quarter, which overshadowed its otherwise strong second-quarter financial results. For its second quarter of calendar year 2025, Coherent reported revenue of $1.53 billion and an adjusted earnings per share (EPS) of $1.00, beating Wall Street's expectations on both fronts.
However, the positive results were undermined by the company's forecast for the third quarter. Coherent guided for third-quarter revenue of approximately $1.53 billion, which came in slightly below analysts' consensus estimate of $1.54 billion. This weaker-than-expected outlook signaled potential headwinds, leading investors to focus on future growth concerns rather than the solid quarterly performance, prompting a sell-off in the shares.
Coherent is up 83.5% since the beginning of the year, but at $356.61 per share, it is still trading 16.5% below its 52-week high of $426.89 from June 2026. Investors who bought $1,000 worth of Coherent’s shares 5 years ago would now be looking at an investment worth $5,582.
