- Corning stock fell 16% after its earnings report, marking its worst single-session decline in six years, per Barron's
- Corning shares dropped on tepid Q3 sales guidance, leading a broader rout across optical stocks, per CNBC and Yahoo Finance
Why it matters: Corning's 16% plunge — its worst in six years — dragged the broader optical-stocks sector lower, with the selloff pinned to tepid Q3 sales guidance rather than the Q2 print itself, signaling the market sees near-term demand cooling faster than the results suggested.
