Lumentum (LITE): InP Inside the AI Optical Super-Cycle – but Priced Like It Already Won
Lumentum is a high-quality, vertically integrated indium-phosphide (InP) optics supplier sitting directly in the slipstream of the AI data-center build-out, with record revenue, rapidly recovering margins, and a second growth engine emerging in optical circuit switching. The business is strong, strategically relevant, and executing well - but the stock, up ~240% YTD and trading near 195x trailing earnings, already reflects a lot of optimism. Great business, stretched valuation: accumulate on dips and use hedges or smaller sizing to keep the upside while managing risk.
