Investment Strategy

The investment objective of the Buffalo Mid Cap Fund is long-term growth of capital. The Mid Cap Fund normally invests at least 80% of its net assets in equity securities, consisting of domestic common stocks and preferred stocks of medium capitalization (“mid-cap”) companies — companies, at the time of purchase, with market caps within the range of the Russell Midcap® Growth Index ($1.1 billion to $28.6 billion, as of 6/30/16).


Our focus has always been on investing in secular growth companies we believe are attractively-priced with strong balance sheets. We remain convinced the inefficiencies inherent in the small and mid-cap market spectrum, in addition to where we are in the economic cycle, are best suited for disciplined, active management of the portfolio.

Equity markets got off to a strong start in the first quarter of 2017, thanks to an improving economic outlook. In February, small business optimism, as measured by the National Federation of Independent Businesses, was at its highest level in 12 years. In addition, the University of Michigan’s March consumer confidence survey showed that consumers were more confident in the economy than they have been at any time since 2000. Against this backdrop, growth stocks outperformed value stocks, led by technology, health care, and consumer discretionary companies. The recent strength in infrastructure companies, banks, and high-tax-rate stocks stalled late in the quarter when, following Congress’s failure to agree on a health care reform bill, investors began to question the Trump administration’s ability to enact elements of its pro-growth agenda. Within commodities, the price of West Texas Intermediate (WTI) crude oil fell 6% during the quarter in response to better than expected U.S. oil inventories and production.

The Russell 3000 Index advanced 5.74% in the first quarter and larger cap stocks outperformed smaller cap stocks. The Russell 1000 Index returned 6.03%, followed by the Russell Mid Cap Index return of 5.15%, and the Russell 2000 Index result of 2.47%. The Russell Micro Cap Index advanced just 0.38% in the quarter. The Russell 3000 Growth Index outperformed the Russell 3000 Value Index by 5.64%. Technology was the best performing sector during the quarter while the energy sector was the worst performer, driven by the decline in crude oil.


The Buffalo Mid Cap Fund generated a return of 4.60% for the quarter which underperformed the Russell Midcap Growth Index return of 6.89%. The Index was primarily driven higher by contributions from the health care, information technology, and consumer discretionary sectors. The Fund’s relative underperformance was a result of difficult stock selection in the consumer discretionary, staples and health care areas. Positive stock selection in financials and the real estate sectors helped partially offset soft relative performance in the areas mentioned above. Also negatively impacting performance was our attention to valuation as we trimmed stocks throughout the quarter that continued to move higher. We are actively deploying capital into areas we believe have a more favorable risk/reward profile.

The fund’s consumer discretionary sector experienced negative selection effect in the quarter with both Tractor Supply Company and Advanced Auto Parts contributing to the underperformance. Both companies were impacted by unfavorable weather. Advanced Auto was also impacted by rumors of Amazon more aggressively entering the automotive aftermarket parts space. Despite the weakness from both stocks this period we remain positive on the long term fundamentals of both companies and believe the valuation profiles are compelling.

The fund’s financials performed well in the quarter. MSCI was the sectors top contributor with a total return of approximately 24%. The company, which provides benchmark indexes and portfolio risk analytics tools to institutional investors, benefited from the growth in ETFs and risk management solutions. MSCI operates an attractive business model that has a substantial recurring revenue stream with meaningful barriers to entry.


The setup for 2017 appears to bode well for both accelerated economic growth and performance of U.S equities. The new administration’s focus on deregulation, infrastructure spend, and tax reform point to a more pro-growth, business-friendly environment. Investors are now keeping a close eye on President Trump’s ability to pass meaningful tax reform, especially after promises of healthcare reform have so far fallen short. Inability to provide tax reform may cause market volatility though expectations for the timing of results are being actively managed by the new administration.

While we are pleased with the number of positions in the portfolio, we continue to look for additional ideas that could provide greater risk adjusted return potential. We have spent considerable time over the past few months analyzing companies with a greater cyclical profile that could stand to benefit from factors like accelerating job growth, improved construction activity, and increased energy production. We would expect those kinds of companies to outperform in this environment of an elongated economic cycle. While we have added some new positions in these areas, we are remaining true to our process of identifying what we believe to be beneficiaries of long-term trends and implementing our valuation discipline. We continue to actively reduce stocks with potential disproportionate downside risk and appreciate your continued support and confidence.

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 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.

The Buffalo Mid Cap Fund received 2 stars among 576 for the three-year, 2 stars among 502 for the five-year, and 3 stars among 370 Mid-Cap Growth funds for the ten-year period ending 6/30/17.

In each Morningstar Category, the 10% of funds with the lowest measured risk are described as Low Risk, the next 22.5% Below Average, the middle 35% Average, the next 22.5% Above Average, and the top 10% High. Morningstar Risk is measured for up to three time periods (three, five, and 10 years). These separate measures are then weighted and averaged to produce an overall measure for the fund. Funds with less than three years of performance history are not rated.
