Jim Simons' Renaissance Technologies drastically reduced its holdings in Coeur Mining (CDE), selling 92.5% of its position during the second quarter of 2026. The quantitative fund's stake fell from 6.87 million shares to approximately 513,900. This move is a sharp reversal from the first quarter, when the firm had increased its holdings in the mining company by nearly 900%.

This trade was disclosed in a quarterly 13F filing, which reflects positions held as of June 30, 2026, and doesn't represent the firm's current-day holdings. During the second quarter, Coeur Mining reported record revenue and cash flow, driven by recent acquisitions. However, the company's earnings per share missed analyst expectations. Coeur also initiated a significant share buyback program and paid its first dividend in this period.
