   Portfolio Manager Q&A

The investment objective of the Buffalo Discovery Fund is long-term growth of capital.

The Fund managers seek to identify companies expected to benefit from innovation and experience growth based on the identification of long-term, measurable secular trends, and which, as a result, the managers believe may have potential revenue growth in excess of the gross domestic product growth rate.

Companies engaged in innovative strategies are those who, in the Fund managers’ opinion, are engaged in the pursuit and practical application of knowledge to discover, develop, and commercialize products, services, or intellectual property.

Companies are screened using in-depth, in-house research to identify those which the Fund managers believe have favorable attributes, including attractive valuation, strong management, conservative debt, free cash flow, scalable business models, and competitive advantages.


To us, innovation means to discover and transform new ideas into meaningful commercial value. The greater the economic impact and the longer the staying power, the better.

We seek under-appreciated stock opportunities in companies where thoughtful management teams are in a favorable position to use innovation for market advantage and sustained shareholder value creation.

Morningstar Rating™

The Morningstar Rating™ for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The Morningstar Rating does not include any adjustment for sales loads. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating™ for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating™ metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.
