The optics complex is rallying together at midday Tuesday, and the leadership has flipped from yesterday. Coherent‘s (NYSE:COHR | COHR Price Prediction) stock is up 16% to $422, leading the group after lagging into Monday’s close.
Lumentum‘s (NASDAQ:LITE) stock is climbing 13% to $1,024, crossing the $1,000 psychological level. Applied Optoelectronics (NASDAQ:AAOI) stock is adding 8% to $201, extending its standout 2026 run.
The move is broader than any single headline. After several choppy weeks, the optics complex spanning Coherent, Lumentum, and Applied Optoelectronics is being repriced together.
Coherent: Laggard Turns Leader
Coherent’s stock was the laggard among the three into Tuesday, down 4% over the prior week. Today’s jump suggests rotation into the broader optics complex rather than narrow momentum chasing.
The fundamentals support the move. In fiscal Q3 2026, Coherent posted revenue of $1.805 billion, up 21% year over year (YoY), with its Datacenter and Communications segment growing 41% to $1.361 billion, now 75% of total revenue. CEO Jim Anderson cited “exceptionally strong demand across our datacenter and communications businesses.”
NVIDIA‘s (NASDAQ:NVDA) $2 billion investment in Coherent, deepening their laser and optical networking partnership, remains a structural tailwind. The valuation isn’t cheap, with COHR stock trading at a forward P/E ratio of 49x.
Lumentum Crosses $1,000
Lumentum stock crossing $1,000 carries weight beyond the round number. LITE is a larger-cap, institutionally held name, so the price level matters for index and ETF flows.
The setup is fundamentally strong. The company’s fiscal Q2 2026 revenue came in at $665.5 million, up 66% YoY, and Lumentum guided fiscal Q3 2026 revenue to $780 million to $830 million, more than 85% YoY growth. Lumentum also disclosed an optical circuit switch backlog of more than $400 million and an incremental co-packaged optics order for first-half calendar 2027.
CEO Michael Hurlston described Lumentum as “mission-critical to the world’s AI leaders.” Analysts carry an average price target of $1,105 on LITE stock.
Applied Optoelectronics Extends Its 2026 Lead
Applied Optoelectronics is the smallest-cap of the trio but the biggest 2026 percentage gainer. Today’s 8% session adds to a year-to-date (YTD) gain of 433% into Monday’s close.
Applied Optoelectronics’ Q1 2026 revenue rose 51% YoY to $151.14 million, with the datacenter segment more than doubling to $81.4 million on 800G transceiver demand. CEO Thompson Lin guided Q2 2026 revenue to $180 million to $198 million and emphasized “significantly larger growth expected starting in Q3 as additional capacity comes online.”
AAOI stock carries more execution risk than peers, with a beta of 3.76 and ongoing operating losses despite the revenue ramp. Investors should weigh the upside against this elevated volatility profile.
The Broader AI Optics Thesis and the Risks
The unifying driver is hyperscaler capex flowing into 400G, 800G, and 1.6T optical transceivers connecting GPUs, racks, and entire datacenters. However, these optics stocks are extended winners.
Coherent stock is up 449% over one year, Lumentum stock 1,255%, and AAOI stock 1,219%. Premium valuations and customer concentration with a handful of hyperscalers make this a volatile group, as last week’s broad pullback demonstrated.
Prudent investors can size their positions accordingly, treating today’s broadening rally as confirmation of an established trend rather than a fresh entry signal. Investors can watch for hyperscaler capex commentary, 800G and 1.6T transceiver ramp updates, along with the next earnings prints from each name.
