Applied Optoelectronics Rips 24%, Lumentum Jumps 17%, Coherent Rallies 13% as Optics Trade Catches Fire

"The optical-networking complex is ripping higher at midday Monday, with all three of the group's marquee names posting double-digit gains. Applied Optoelectronics ( NASDAQ:AAOI) is leading the basket, up 24% to $184.51, while Lumentum ( NASDAQ:LITE | LITE Price Prediction) trades 17% higher near $1,057. Coherent ( NYSE:COHR) rounds out the trio, up 13% to roughly $377.60."

"The rally is essentially a mirror image of last Thursday's sector-wide pullback, when AAOI, LITE, and COHR shares fell sharply in unison. Today's bid reflects renewed enthusiasm for AI data center capex and the optical connectivity layer that links hyperscale GPU clusters. Year to date, Applied Optoelectronics stock is up 420%, Lumentum shares are up 184%, and Coherent has gained 104%."

"Applied Optoelectronics posted Q1 FY26 revenue of $151.14 million, growing 51% year over year (YoY) on surging demand for 800G transceivers used in AI workloads. The data center segment more than doubled to $81.4 million, including Applied Optoelectronics' first volume shipment of 800G product to a large hyperscale customer. Management guided Q2 revenue to $180 million to $198 million and signaled significantly larger sequential growth starting in Q3 as expanded Houston capacity comes online."

"Applied Optoelectronics CEO Thompson Lin pointed to "strong customer engagement around our 800G transceivers and 1.6 Tb products" as AI-driven data center investments accelerate. Applied Optoelectronics is the day's standout, with AAOI stock advancing from Friday's close of $148.94. The move follows the company's Q1 FY2026 report last week and a sharp drawdown in the same session."
