Can AXT Keep Crushing Every AI Stock After a 6,890% Run?
AXT has enjoyed an eye-popping one-year 6,890% return and its latest 30% daily gain tied to broader semiconductor strength, highlights the company's leading position in the explosive AI data-center optics space.
Investors woke up to a semiconductor sector on fire after Taiwan Semiconductor Manufacturing ($TSM) posted a beat-and-raise quarter, confirming AI spending remains red-hot and sent chip names higher across the board.
No stock captured that momentum quite like AXT ($AXTI). Its shares surged 30% on the news, a single-day move that sits atop a one-year total return of 6,890% – far ahead of the S&P 500's 33% gain and outperforming every other AI-tied name investors have tracked. Let's see what the numbers actually tell us about this outlier.
What AXT Actually Makes – And Why AI Data Centers Crave It
AXT produces indium phosphide (InP) compound semiconductor wafers. These wafers form the heart of high-speed optical transceivers that shuttle enormous volumes of data inside hyperscale AI clusters. Without them, the massive parallel processing that powers today's models simply bogs down. In short, AXT sits at the foundational layer of the AI buildout.
It has been two weeks since the one-year mark of President Trump's April 2, 2025 "Liberation Day" tariff rollout. Those policies initially squeezed AXT's China-based operations with permit delays on InP shipments, and full-year 2025 revenue fell 11% to $88.326 million. Gross margins narrowed to 12.7%, and the company recorded a $0.49 per-share net loss.
Yet the AI wave proved stronger. Fourth-quarter InP revenue reached $8 million while the backlog topped $60 million. Management guided for sequential revenue growth in the current quarter and plans to double InP capacity by repurposing existing gallium arsenide lines by the end of 2026 – a low-capital way to meet demand. Investors who ignored the tariff headlines and focused on the order book drove the stock higher than any peer.

Nosebleed Valuations Meet Fresh Momentum
The stock now trades at a price-to-sales ratio of 31.26 with a forward P/E around 24x, though AXT remains unprofitable on a trailing basis. For context, Advanced Energy Industries ($AEIS) returned 244% over the same period while Amkor Technology ($AMKR) gained 151%. AXT's InP exposure simply delivered a different league of results.
Granted, that kind of outperformance leaves the stock vulnerable to any slowdown in AI capex. That said, yesterday's 30% surge shows the market still believes the tailwinds have legs. AI data centers are growing exponentially larger in terms of their power, and existing copper interconnects are reaching their limits. Optics is the linchpin for data center expansion – the exact tailwind behind InP demand.
AXT's Q1 2026 results are scheduled for April 30, which will reveal whether the backlog is translating into shipments and whether capacity plans stay on track.
Bottom Line
AXTI delivered returns that turned a tiny name into one of the market's biggest winners, but current valuations price in a lot of perfection. For risk-tolerant investors who size positions small and believe AI infrastructure spending stays robust, the stock can still deliver further gains.
Yet remember: AXTI remains a small, volatile name with China-based production subject to tariff and geopolitical risks. It remains unprofitable on a trailing basis and carries nosebleed valuations after its massive gains. The optics opportunity is real and tied to real projects, but it doesn't remove the need for tight risk management for both the company and investors alike.
