Lumentum Down 40% in a Month Despite Blowout Quarter

Lumentum (NASDAQ:LITE) has lost 40% of its value in a month, falling from $987.99 on October 13 to $592.82 — even though the company just posted its strongest quarter in years. Getting back to $1,000 would take a 68.7% gain from here. The stock has cleared that mark before, setting a 52-week high of $1,143.

The drop isn't Lumentum-specific. Tech is trailing every other major sector as NVIDIA (NASDAQ:NVDA) keeps sliding, and the selloff across AI hardware and chip names is dragging the whole optics trade down. Lumentum fell another 5% on the day.

What did the quarter actually deliver?

On November 2, Lumentum reported fiscal Q1 2027 results that beat on both lines. Adjusted EPS came in at $4.57 against a $4.22 consensus, and revenue of $1.26 billion grew 136.5% year over year.

CEO Michael Hurlston said: "Lumentum built on its strong momentum in the first fiscal quarter of 2027, delivering growth across all our businesses, with pump lasers and optical circuit switches (OCS) being the leading contributors."

The quarter also brought a second major near-packaged and co-packaged optics (NPO/CPO) design win, backed by purchase commitments exceeding $5 billion. Co-packaged optics put the optical engine right beside an AI chip, so data moves as light instead of over copper. Lumentum guided fiscal Q2 2027 revenue to $1.575–$1.625 billion.

What do analysts still think?

Coverage stays bullish: 5 Strong Buy, 18 Buy and 5 Hold ratings, with no Sells. The average price target sits at $1,069.19. That gap between strong results and a falling share price points to plain profit taking in AI optics.

How are Coherent and Applied Optoelectronics faring?

Coherent (NYSE:COHR) trades at $214.24, down 8% — a steeper daily drop than Lumentum's. Its November 4 report showed fiscal Q1 2027 revenue of $2.37 billion, up 49.9% YoY, with Datacenter & Communications making up 82% of sales.

Applied Optoelectronics (NASDAQ:AAOI) has fallen 50% over the past month to $49.08, down 7% against the prior close. Its Q3 2026 revenue, reported November 5, rose 127.5% YoY to $269.88 million. But GAAP net income of $6.3 million leaned on $8.2 million of other income and $3.1 million of interest income, masking a GAAP operating loss of $1.44 million.

How do the business models differ?

Lumentum leans on lasers and optical subsystems, with pump lasers, cloud transceiver modules and optical circuit switches driving growth. Its NPO/CPO wins tie it to the next wave of AI chips, and it's scaling a factory in Greensboro, North Carolina.

Coherent sells across the full optical signal chain, from materials through lasers and transceivers, positioning itself as an independent supplier to hyperscalers and chipmakers. Applied Optoelectronics pairs hyperscale transceivers with a cable TV broadband business and is mid-way through a large capacity expansion.

What stands between LITE and $1,000?

The bull case rests on sold-out optoelectronic capacity, rising optical circuit switch demand and the multi-billion commitments behind the newest design win. A recovery likely needs AI data center optics demand to hold up and AI hardware sentiment to stabilize.

The bears have their own list. Risk factors in Lumentum's release include tariffs, export controls, supplier execution, debt servicing and swings in product mix — and sentiment across AI hardware can turn fast, as Applied Optoelectronics' 50% slide shows.

The next test is whether fiscal Q2 revenue lands inside the guided range, and whether the selloff across optics names eases. A strong quarter with steady demand could rebuild confidence; a softer outlook may extend the pullback. Expect elevated volatility until the AI hardware selloff ends.
