David Einhorn adjusts stake in Core Natural Resources

What happened: In Q1 2026, Magnolia Group, LLC sold 67,000 shares of Core Natural Resources (CNR), a $6.38 million move, while Greenlight Capital, which holds a stake in CNR, saw its funds return 6.5% in the same period.

Market impact: This contradicting activity from two prominent investment managers may cause uncertainty among investors, potentially affecting the coal sector's valuation and CNR's stock price. Greenlight's bullish stance on CNR, driven by increased coal demand, contrasts with Magnolia's bearish sell-off.

What to watch next: CNR's Q2 earnings report (scheduled for July 2026) will provide insight into the company's performance and Greenlight's confidence in its coal demand thesis. Additionally, any further changes in Magnolia's or other major investors' stakes in CNR will signal market sentiment towards the company.
