In a recent 13F filing for the period ending June 30, 2026, David Tepper's Appaloosa Management revealed it had completely liquidated its position in Corning Inc. (GLW). The firm sold all 1.13 million shares, which were previously valued at approximately $153.58 million and represented a 2.59% portfolio weight. It's important to remember that 13F filings are delayed disclosures, reflecting trades made in the prior quarter and not necessarily the fund's current holdings.
The sale occurred during a quarter where Corning reported strong financial results, with a 17% year-over-year increase in core sales and a 30% rise in earnings per share, largely driven by demand from the artificial intelligence sector. Appaloosa's filing also showed a broader portfolio rotation, exiting several technology positions while increasing stakes in other AI-related infrastructure companies.
