    Corning Drops 51% from June Highs as Valuation Deflates from 95x PE Peak

    Question

    Corning Drops 51% from June Highs as Valuation Deflates from 95x PE Peak

    Direct answer

    Corning shares have experienced severe multiple compression, losing 51% of their value from a peak of $255.69 in June to approximately $125 ahead of its upcoming earnings report. The drawdown follows an intense re-rating earlier this year when market excitement around AI optical connectivity contracts with Nvidia and Amazon pushed the trailing price-to-earnings ratio to 95x. The operational picture remains divergent from the stock correction, with core earnings per share rising 30% year-over-year. Market attention is centered on whether data center optical connectivity demand can validate mid-term margins as the equity resets from speculative multiples to industrial hardware benchmarks.
