Morgan Stanley Raises Outlook for Multiple North American Optical Communication Stocks

Morgan Stanley's April 20 report raised targets across North American optical networking names, calling supply tightness through at least 2027 the sector's anchor thesis — the group has rallied ~20% in the past month and fresh capital is still flowing in.

01

Why is optical networking trading in a league of its own?

The sector commands valuations far above storage and HDD peers. Three hard-to-disprove theses underpin the premium.
First, supply stays tight through at least 2027 — most firms' order books are full for this year and into next. The debate has shifted from "can they win orders" to "how much margin can they extract."
Second, margin upside is beating expectations — leaders now set prices, Asian fiber spot prices have jumped 75%, and incremental gross margins top 30%.
Third, valuation logic has reset — 2028E P/E ratios sit at 20–25× broadly, with some names near 40×, well above the historical low-teens. This means → the market is pricing optical networking as AI's "pure upside, no margin cannibalization" play.
02

Where exactly is the supply bottleneck?

The chokepoint is indium phosphide (InP) — a semiconductor material used to make the high-speed laser chips inside optical modules. In plain terms = no InP, no 1.6T modules.
Leading suppliers have announced expansion plans, but the shift to 6-inch wafers is creating yield problems that cannot be fixed quickly.
There is also a technology-route split on laser chips for 1.6T modules — market estimates for the CW laser share range from 30% to 50%. This means → with the route unsettled, no supplier dares go all-in on one line, which locks the bottleneck in place even longer.
03

How does Morgan Stanley rank the four names?

The report's priority order: Coherent → Corning → Lumentum → Ciena, each with a distinct role in a portfolio.
Coherent (COHR.US) — top pick for upside. Base target $290, bull case $400. Revenue growth expected at 19%, 26%, 20% for 2026–2028. Core beneficiary of OCS (optical circuit switching) and CPO technology.
Corning (GLW.US) — defensive anchor. Target $140, bull case $192. The global fiber leader with the strongest earnings visibility and lowest volatility. 30%+ incremental gross margin supports 20%+ EPS growth through 2028.
In plain terms = Coherent is the offense play, Corning is the ballast.
04

What are Lumentum and Ciena each betting on?

Lumentum (LITE.US) — the cycle-realization play. Target $710, bull case $1,000. The dominant InP laser-chip maker, already locking in profits through aggressive price hikes. 2026 revenue growth expected at 77%; gross margin could approach 50% by 2028.
This means → Lumentum's thesis is "chips stay scarce + pricing power holds." The buy-side's bull-case $40 EPS for 2028 rests squarely on that assumption.
Ciena (CIEN.US) — the long-runway compounder. Target $405, bull case $540. Dominates North American long-haul DCI transmission with a 63% market share. Nokia and Cisco's multi-haul products won't pose a real threat until 2027. 2026 EPS growth expected at 119%.
05

What is the biggest risk of entering now?

With valuations stretched, the sector will inevitably shift from a broad rally to stock-by-stock divergence — earnings delivery, technology positioning, and capacity ramp-up will determine individual trajectories.
Key risks to watch: AI hyperscaler capex undershooting expectations, faster-than-expected laser-chip capacity expansion triggering a price war, technology-route shifts devaluing legacy products, and tariff-policy changes.
This reflects a structural paradox: the higher the sector climbs, the more fragile the "can't be disproved" thesis becomes — once any single assumption breaks, the drawdown will be proportionally larger.
