Why is Coherent (COHR) stock rocketing higher today

What happened

Coherent shares jumped 5.6% in the afternoon session after StoneX analyst Cody Acree started coverage with a Buy rating and a $425 price target, which the firm said implies about 103% upside.

Confirmed

Global impact / market context

A new Buy rating can draw investor attention to Coherent's plan to expand six-inch indium phosphide capacity, which means more production of lasers used in AI data-center optics, potentially supporting future revenue.

Analyst inference

Coherent stock is extremely volatile, with 86 moves greater than 5% over the past year, so this gain suggests the market found the analyst call meaningful but not something that would fundamentally change its view of the business.

Analyst inference

What to watch

1. Management has targeted doubling six-inch indium phosphide capacity in the September quarter and more than another doubling by the end of 2027, which is capacity used for lasers in AI data-center optics. Confirmed
2. Coherent expects revenue from its PhotonLink platform to start ramping in the fourth quarter of calendar 2026, a proposal investors can track against later company updates. Proposed
3. Watch whether the more than 10 customer engagements each in co-packaged optics and near-packaged optics convert into orders, which would show whether capacity spending turns into actual sales. Analyst inference
