Highlights
Biggest Buys
Core Natural Resources (CNR) Aquamarine Capital initiated a new position in Core Natural Resources, acquiring 8,100 shares at an average purchase price of approximately $82 per share. While the specific public operational details of "Core Natural Resources" under the CNR ticker can be niche, Guy Spier's investment indicates he has identified what he perceives as a compelling value proposition or special situation within this natural resources entity. This aligns with his investment framework of finding often overlooked or misunderstood companies that offer a significant margin of safety.
Biggest Sells
Arch Resources Inc. (ARCH-OLD) Spier sold 8,100 shares designated as ARCH-OLD, representing the legacy holding in Arch Resources Inc., completely liquidating this position at an average selling price of approximately $119 per share. Arch Resources is a U.S. coal producer. The "-OLD" ticker indicates these were likely shares from a previous corporate structure or an older holding period. This sale finalizes Aquamarine's exit from this particular coal investment. The identical share count to the CNR purchase suggests a potential direct redeployment of this capital.
Guy Spier's Q1 2025 reported transactions at Aquamarine Capital were notably precise, highlighting a direct shift from a legacy coal investment (Arch Resources - OLD) to a new venture in another natural resources company (Core Natural Resources). This focused reallocation, involving an identical number of shares in the sell and the new buy, suggests a deliberate rotation within the resources sector. Such a move is characteristic of Spier's value investing principles: patiently waiting for opportunities and making thoughtful adjustments when a more attractive, ethically aligned investment that meets his margin of safety criteria is identified.
