Core Observation
Evercore ISI analyst Amit Daryanani released a note on 27‑10‑2026 highlighting that Lumentum (NASDAQ: LITE) rose 6.33%, Ciena (NYSE: CIEN) 4.41%, Coherent (NYSE: COHR) 6.22% and Nokia (NYSE: NOK) 2.95% on Monday as optical‑related equities rallied.
First Driver – FCC Import Restrictions
Daryanani pointed to an upcoming Federal Communications Commission (FCC) rule expected to limit imports of foreign‑produced optical transceivers by the end of the first quarter of 2027. The rule would effectively remove Chinese suppliers from the U.S. market for next‑generation 3.2‑terabit transceivers. He noted that roughly two‑thirds of all optical transceivers in use today are Chinese‑made, and that the restriction would create a headwind for the pace of artificial‑intelligence (AI) deployment while benefitting U.S. and allied manufacturers.
Second Driver – Indium Phosphide Capacity Concerns
Asian media reports indicated that expansion plans at indium‑phosphide manufacturers are wavering, with yields averaging below the levels required for forecasted supply growth. The analyst explained that the optics sector has shifted from a five‑year cycle to near‑annual increases in lane speeds, and that Chinese suppliers face challenges adding capacity at the latest speeds with acceptable yields.
Third Driver – Confidence in AI Spending
A renewed confidence in the durability of AI spending formed the third catalyst. Daryanani observed that earnings for the sector have so far appeared healthy, and cited Meta’s recent equity raise and SpaceX’s financing commitment as signals of ongoing AI‑related demand.
Analyst’s Conclusion
The analyst concluded that despite a sell‑off the previous week, the optics space remains attractive as a critical bottleneck to the AI build‑out. He added that recent news flows suggest domestic companies are poised to benefit from the regulatory action and from being technology leaders.
