Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period? 

The Plumb Funds are pleased to present our March 31, 2026, fiscal year results to you, even in a down market caused by geopolitical risks. The fiscal year of 2026 proved to be an eventful period for financial markets, most notably the United States entering into a conflict with Iran on February 28th that sent crude oil prices dramatically up and hence gasoline prices at the pumps.

The largest contributors to the Plumb Balanced Fund included Modine Manufacturing, AAR, Exxon Mobil, Phillips 66, and Ubiquiti. The largest detractors for the quarter were Microsoft, American Express, Toast, Mercardo Libre, and Visa.
