On August 7, Lumentum rose 3.23% in regular trading, trading at $885.82/share, with turnover of $431 million. The stock continued its upward momentum driven by dual catalysts of AI computing capacity constraints and an optimistic earnings outlook.

On the news front, a research report highlighted that the AI computing power industry chain has entered a deep acceleration phase where downstream demand is forcing upstream capacity expansion. As a leading upstream optical component supplier, Lumentum's core optical component capacity may be sold out through 2028, significantly intensifying supply shortage expectations. Additionally, the optical communication sector saw broad-based strength during the session, with Applied Optoelectronics up 7.95% and Coherent gaining notably, reinforcing sector-wide momentum.

Meanwhile, the company is scheduled to report quarterly results after market close on August 11. Market consensus expects revenue of approximately $9.88 billion, representing year-over-year growth of 111.83%, with adjusted EPS of approximately $2.97, up 271.06% year-over-year. The core drivers are sustained shipments of high-end components and product mix upgrades lifting average selling prices.
