"The Amalthea Fund gained 0.95% in Q4 2025, underperforming the index due to short-book headwinds, while the manager detailed a structured framework for navigating potential bubble environments using historical analogies."
For the quarter ending December 2025, Bronte Amalthea Fund returned 0.95% (-2.24% for the month of December), underperforming the MSCI ACWI's 2.47% quarterly return. Gains from large-cap longs like Regeneron and Alphabet were partially offset by underperformance in DSM-Firmenich and ongoing headwinds in the short book, particularly in Biotech and Materials. The letter discusses the AI bubble debate by contrasting current tech market conditions with historical bubbles (the late 1990s dot-com boom, the 2021 NFT wave) and explains how the analyst team utilizes historical analogies to source and evaluate both long and short investment ideas. Additionally, Bronte announced the expansion of its analyst team with the hires of Dan Wagner and Alex Rose-Innes.
