Shares of Applied Optoelectronics (NASDAQ:AAOI) jumped 6% to $119.10 in early trading Tuesday, rebounding from a rough Monday session on fresh news of a major Texas manufacturing expansion. Shares of Lumentum (NASDAQ:LITE | LITE Price Prediction) also climbed as the AI optics trade caught a fresh bid while Coherent (NYSE:COHR) stock rose slightly.
Lumentum stock added 5% to $806.81, while Coherent stock moved 1% higher to $310.11. The broader tape is helping somewhat: a cooler-than-expected June Consumer Price Index (CPI) reading pushed the NASDAQ 100 higher and reopened risk appetite in high-beta AI hardware names.
Applied Optoelectronics is the ticker with the actual news. Lumentum and Coherent are moving in sympathy, riding the same 800G and 1.6T transceiver demand story from hyperscalers building out AI data centers.
Texas Expansion Fuels the AI Optics Trade
Applied Optoelectronics broke ground on its Pearland, Texas campus, adding nearly 400,000 square feet of manufacturing capacity dedicated to 800G and 1.6T optical transceivers. Those parts are core plumbing for AI data-center networking, connecting graphics processing units (GPUs) at speeds copper interconnects can’t reach.
CFO and Chief Strategy Officer Stefan Murry framed the build-out as supporting long-term growth and strengthening Applied Optoelectronics’ position as a key supplier to AI and cloud infrastructure markets. The company had already nearly doubled its Houston-area footprint through real estate acquisitions and leases earlier this year, so Pearland extends a plan already in motion.
The context matters here. On the company’s Q1 2026 report filed May 7, Applied Optoelectronics posted revenue of $151.14 million, up 51% year over year (YoY), with data-center revenue of $81.4 million more than doubling from $32.05 million. Applied Optoelectronics CEO Thompson Lin said the company is “well positioned to become the premier high-volume U.S. producer of AI-focused data center transceivers and optics.”
The company’s Q2 2026 revenue is guided to $180 million to $198 million, with significantly larger sequential growth expected in Q3 as new capacity comes online. Applied Optoelectronics exited Q1 with capacity of nearly 100,000 units of 800G transceivers per month.
Peers Ride the Sympathy Bid
Lumentum has no company-specific catalyst today, but the read-through is direct. Lumentum’s Q3 FY2026 revenue hit a record $808.4 million, up 90% YoY, and non-GAAP operating margin expanded 700 basis points sequentially to 32%. CEO Michael Hurlston flagged co-packaged optics (CPO) and optical circuit switches (OCS) as the next legs of growth.
Lumentum’s OCS backlog is above $400 million, and the company booked a multi-hundred-million-dollar CPO order deliverable in first half calendar 2027. The company’s Q4 FY2026 guidance calls for revenue of $960 million to $1.01 billion.
Coherent is similarly moving on the theme rather than its own news. The company posted Q3 FY2026 revenue of $1.81 billion, up 20.5% YoY, and is scaling indium phosphide (InP) wafer production in Texas. NVIDIA‘s (NASDAQ:NVDA) $2 billion investment in Coherent and its recent S&P 500 inclusion give it a similar AI-optics profile.
The Bull and Bear Cases on AAOI Stock
The bull case for Applied Optoelectronics stock is straightforward. Hyperscaler demand for 800G and 1.6T optics is accelerating, and Pearland gives the company real U.S. capacity to sell into it. The consensus analyst target price sits at $151.30, above today’s level.
The bear case is equally clean, though. AAOI stock is up 221% year to date (YTD), with a forward P/E ratio of 84x and a beta of 3.69. Customer concentration and execution risk on the 800G ramp mean investors should consider keeping their position sizes modest.
For context on the wider theme, our team broke down the setup in 7 Stocks Powering the AI Boom. Lumentum shares are up 108% YTD and Coherent shares are up 67% YTD, so today is a sharp bounce inside of a volatile uptrend.
What to Watch Next
While you might not find a pure-play optics or photonics ETF, there’s a broad proxy in the iShares Semiconductor ETF (NASDAQ:SOXX). However, optics is only a small slice of the fund, and concentration risk in the top chip names shouldn’t be dismissed.
Traders can watch for whether AAOI stock holds above $115 into the close and starts building a base after the recent drawdown. Lumentum’s Q4 FY2026 print is the next scheduled catalyst on the calendar for the peer group.
Coherent’s Texas InP ramp and NVIDIA partnership give the sector a second anchor beyond Applied Optoelectronics. Market watchers may want to size their positions carefully given the volatility that has defined all three names this quarter.
