What Happened?
Coherent (COHR) is sliding again, dropping more than 5% in premarket/after-hours trading to roughly $395, down from a close of $417.43 on Wednesday.
The selling has little to do with the company itself. The whole group of optical and photonics stocks is taking a breather after a big run.
The recent move went both ways. On Tuesday, Coherent stock soared 17%, and Lumentum jumped 14%.
The rally was sparked by Nvidia CEO Jensen Huang, who praised demand for optical networking parts. That single comment lit up the whole optical group.

Two days of buying turned into selling on Wednesday.
Coherent stock closed down 2%, and Lumentum dropped more than 8% in Wednesday’s trading. Then on Thursday, the selling picked up before the open.
Coherent stock fell nearly 5% in premarket. After such a sharp rally, this kind of profit-taking is pretty normal.

What the Market Is Telling Us About Coherent Stock
The drop looks like traders cashing in, not a worry about the business. Coherent stock has been one of the hottest names of the year. It is up roughly 115% so far in 2026 and recently hit a 52-week high of $440.
The fundamentals are still strong.
In its most recent quarter, Coherent posted record revenue of $1.8 billion, up 21% from a year ago.
Earnings rose 55% year over year as profit margins expanded.
Management guided for another record quarter ahead, with revenue between $1.91 billion and $2.05 billion. Backlog is also at record levels, with orders now stretching into 2028.
A big vote of confidence came from Nvidia. In March, Nvidia invested $2 billion in Coherent and signed a multi-year supply deal running through the end of the decade.
The partnership covers co-packaged optics, a key technology for AI data centers.

Coherent stock also tends to swing hard, with a beta above 2. So big single-day moves come with the territory.
For now, this looks like the market cooling off after a hot run, not a change in the AI infrastructure story.
