Corning (GLW -7.7%) opened down just slightly after reporting this morning, but ended up plunging to 3-year lows. Q2's 16% Y/Y drop in display glass sales more than offset modest increases elsewhere, and stoked fears that there's no bottom in sight for the market, given weak LCD TV demand. During its earnings call, Corning noted macro issues are affecting multiple businesses, and that it's seeing "mixed performance" in China, where it's about to build a new plant. AUO -7.6%. LPL -4.1%.
