New York, June 16, 2026, 13:10 EDT. Lumentum stock is lower as shares pull back from levels hit in the recent AI optics rally. Peers are facing valuation questions as the group gives up some gains.
- Lumentum shares fell around 7% in intraday trading, pulling back after a strong recent rally.
- AI-infrastructure and tech names lost ground, weighing on the group. Still, the optical-networking outlook did not change.
- Fiscal fourth-quarter results are the next big catalyst for the company, with attention on whether Lumentum hits its revenue and margin guidance.
Lumentum Holdings Inc. shares dropped 7.27% to $887.68 as of 1:07 p.m. EDT on Tuesday, losing some ground after a strong run in AI-infrastructure names. The stock traded between $863.41 and $961.68 earlier in the day, Google Finance data showed. The slide didn’t appear tied to fresh company news, but came after the stock posted a 16.5% gain over the past week, according to Simply Wall St. Google
Broader market action weighed. Reuters said Tuesday that investors moved money into sectors seen as more tied to the economy, while the S&P tech index slipped after rallying the previous session. Trading Economics flagged a drop in AI-infrastructure and chip stocks. The Nasdaq 100 lost about 1.4% and Nvidia fell. Against that setup, Lumentum, which is linked to AI data-center spending, dropped even with no new earnings. Reuters
Bulls can still point to the basics. Lumentum makes high-speed optical and photonic parts used in cloud and AI networks. The company’s latest quarter saw revenue jump 90.1% year over year to $808.4 million. Non-GAAP gross margin came in at 47.9%. Non-GAAP figures strip out some accounting items. “Lumentum delivered an exceptional third quarter, with revenue growing 90% year over year to a record $808 million,” Chief Executive Michael Hurlston said.

Wall Street is still mostly bullish, but the stock doesn’t look cheap anymore. On Google Finance, there are 14 Buy ratings, five Holds and no Sells out of 19 analysts. The average 12-month price target is $1,076.76. J.P. Morgan stuck with its overweight rating and kept its $1,130 target. The firm said fears over co-packaged optics, or CPO—which put optical links closer to switch chips for better speed and power use in data centers—are likely overdone. Google
Lumentum faces a bear case on valuation and execution risk. Google Finance listed its price-to-earnings ratio at about 164, so investors are paying 164 times trailing earnings. The stock’s price-to-sales ratio is near 29.93 times, against a communications sector average of 2.50 times, according to Simply Wall St. That service also noted risks from customer concentration, fast-moving technology and supply-chain costs.

Lumentum’s next big event is fiscal fourth-quarter earnings. The focus is on whether the company will hit its guidance of $960 million to $1.01 billion in revenue, 35% to 36% non-GAAP operating margin, and $2.85 to $3.05 adjusted EPS. The stock could still draw buyers looking for more AI optical growth, but after a sharp rally and swings on Tuesday, it doesn’t look cheap—just volatile. Lumentum Investor Relations
