Lumentum has quietly become one of the biggest winners of the AI infrastructure boom. Shares have surged about 570% over the past year, leaving NVIDIA, Dell, and even Micron behind.
The stock rose another 3.82% on October 6 to close at $1,133.40, just below its 52-week high of $1,137.20.
The scale of the rally stands out even in a market obsessed with AI. Over the same 12 months, Micron gained about 457% and Dell rose roughly 308%. NVIDIA gained around 28%.
That means Lumentum delivered more than 21 times NVIDIA’s return. Its market value has now climbed to roughly $101.7 billion.
Why Did Lumentum Stock Rally So Much?
Lumentum makes lasers and optical components used inside data centers, telecom networks and AI infrastructure.
As companies build larger AI systems, they need faster connections between servers and data centers. That has pushed more money into optical networking suppliers.
The numbers have followed.
Fiscal fourth-quarter revenue reached $1.01 billion, up 109.3% year over year. Earnings of $3.23 per share also beat expectations.
Citigroup has pointed to demand for optical circuit switches as another major growth driver.
Lumentum Price Forecast: What is Wall Street Targeting?
After a 570% rally, analysts are sharply divided.
- The average target among 23 analysts is $1,078.75, already around 5% below the latest share price.
- Citigroup is far more bullish, with a $1,400 target implying roughly 24% upside.
- Rosenblatt sees $1,300, while Stifel recently raised its target to $1,232.
- UBS sits at the other end with an $820 target, implying roughly 28% downside.
The rally has already priced in enormous growth. From here, Lumentum will need earnings to keep catching up with its share price.
