Optics stocks rise sharply amid strong earnings and AI-related demand, while Broadcom falls on financing risk concerns.

Optics stocks like Corning, Lumentum, Applied Optoelectronics, and Coherent climbed significantly on strong earnings reports and optimistic future demand, especially driven by AI hardware needs. Lumentum and Coherent reported substantial revenue growth and positive guidance, while Applied Optoelectronics noted demand outpacing production capacity through mid-2027. Meanwhile, Broadcom's shares dropped due to concerns over its $30 billion residual value guarantees tied to AI hardware financing, posing a long-term risk if AI capacity is overbuilt. Investors are watching whether Broadcom stabilizes and if optics suppliers maintain their gains, reflecting a trend to favor component makers over financing-heavy firms in the AI sector.
