Portfolio Managers Jamie Cuellar and Bob Male discuss the foundation for the Buffalo 别错过乐米娱乐官网下载安装(2023趋势新闻) investment strategy – finding companies that are rapidly growing and can benefit from long term trends.


An actively-managed portfolio of smaller-capitalization, rapidly-growing companies that can benefit from positive, long-term trends remains an excellent way to exploit an inefficient market.

“I think what really differentiates us is our process, where we combine the top-down work of looking at trends provided with the bottoms-up fundamental research we do on each company.”

(As of 12/31/22) — Capital markets rallied modestly in the 4th quarter as the S&P 500 Index gained 7.56%, the only positive quarter for 2022. Cooler inflation readings, resilient consumer spending, and better-than-expected corporate earnings buoyed markets during the first two months of the 4th quarter before pulling back in December. Much of the focus remains on the path of future interest rates, recession fears, and the economic and market impact those events may generate in 2023.

Despite the 4th quarter advance, the stock market recorded its worst calendar year since 2008, with a decline of -18.11% for the S&P 500 Index, and a loss of -32.54% for the growth-oriented and technology-heavy Nasdaq Composite Index. Large cap technology stocks and the more interest-rate sensitive assets suffered the most, while value stocks outperformed. In the end, nine of the S&P 500 Index’s 11 economic sectors declined. Energy stocks were the bright spot, recording a gain of 65.72% for the sector while Utilities eked out a gain of 1.57% in 2022.

The damage wasn’t isolated to the stock market as the investment-grade bond indices suffered double-digit losses for the year as well. In fact, a traditional balanced investment portfolio of 60% stocks and 40% bonds suffered the 4th worst drawdown in the past 100 years.

Recapping quarterly results, the broad-based Russell 3000 Index advanced 7.18% in the period. Value stocks significantly outperformed growth stocks to close out 2022, as the Russell 3000 Value Index returned 12.18% versus a return of just 2.31% for the Russell 3000 Growth Index. Relative performance was mixed going down in market cap size as small caps advanced less than large caps in the quarter, while mid cap stocks outperformed both large and small caps. Larger cap stocks returned 7.24%, as measured by the Russell 1000 Index, compared to the smaller cap Russell 2000 Index return of 6.23%, while the Russell Midcap Index produced a return of 9.18% in the quarter.


(As of 12/31/22) — The Buffalo 别错过乐米娱乐官网下载安装(2023趋势新闻) (BUFSX) produced a return of -0.67% for the quarter, a result that trailed the Russell 2000 Growth Index return of 4.13%. Disappointing stock selection was responsible for most of the relative underperformance, but the Fund’s sector allocation impact also weighed on results due to our typical underweight in Energy and Consumer Staples, two of the strongest performing benchmark sectors during the quarter.

The Fund’s results in the Technology area and Industrials were the largest detractors from performance results from a sector breakdown perspective. Within Technology, the portfolio experienced weakness among IT Service holdings including DoubleVerify and Grid Dynamics. Stock selection in Software also lagged on declines by BigCommerce Holdings and Varonis Systems, Inc. Performance within the portfolio’s Industrials exposure weighed on overall results due to declines from Advanced Drainage Systems and PGT Innovations. Both stocks performed poorly as higher interest rates are beginning to impact the companies’ construction markets.


Partially offsetting the lagging areas above was stronger stock selection within Health Care, particularly among the portfolio’s health care equipment and biotechnology companies. TransMedics Group was once again a top contributor to Fund performance as shares advanced nearly 50% during the period. The company’s innovative Organ Containment System (“OCS”) and National OCS Program (“NOP”) continued to see rapid uptake translating to accelerating revenue growth of about 378% year-over-year.

Establishment Labs Holdings, Inc. and Inspire Medical Systems, Inc. that also operate in the health care equipment area were strong performers in the quarter. Within biotechnology, Halozyme Therapeutics advanced over 40%.


Overall, the largest detractors from performance results during the quarter were Privia Health and Palomar Holdings. Privia, a technology-driven platform that enables medical groups, health plans, and health systems transition to value-based care arrangements, performed poorly during the quarter due to sector rotation within Health Care. Also, Privia’s multiple compressed during the period as investor speculation of an imminent buyout of the company waned. Palomar, a specialty insurance company, underperformed during the quarter as its reinsurance costs could potentially increase due to Hurricane Ian in Florida. Additionally, the company’s 3rd quarter earnings were negatively impacted by higher attritional losses. Our view of both companies remains favorable.


(As of 12/31/22) — The direction of the market overall will likely continue to depend on inflation’s trajectory and the amount of economic damage caused by higher interest rates. The inflation picture continues to ebb and flow. While we are seeing a decline in logistics costs, shipping rates, and some commodity prices, component shortages continue to persist. Generally, it seems price increases are moderating but the sustainability of this moderation is questionable.

While the Federal Reserve has already increased interest rates by 425 basis points, market expectations forecast another 50 to 75 basis point increase in this tightening cycle. In response, there has been a growing chorus for the Federal Reserve to slow its pace of tightening and allow previous hikes to make their way through the economy. Meanwhile, global economies continue to slow, especially in Europe where energy prices remain high. While many companies have already lowered financial guidance for the year, we could be in store for another earnings season of decreasing estimates which may possibly bring more market volatility.

Throughout 2022, small cap stocks re-rated for the prospect of a significant slowdown in economic growth in 2023. As a result, we are taking advantage of stocks that are oversold by our analysis. At the same time, we are being cautious with unfamiliar management teams and their ability to navigate a less predictable economy and market volatility. Portfolio positioning is fairly defensive within Technology, with a focus on a steadier IT Services industry and the Communications Equipment industry, which has unique demand drivers due to government subsidies.

The portfolio continues to be underweight Semiconductors and Software relative to the benchmark. We’ve added slightly to Energy sector exposure with higher quality energy-related companies, but the portfolio remains underweight relative to the benchmark. Larger positions within the Fund continue to be companies with recurring revenue streams, or those with strong demand and good visibility into future earnings.

As always, we believe all of our investments could benefit from long-term growth trends and trade at attractive valuations – the cornerstone of our investment process. We thank you for your continued support.

Fundamental Approach

We get to know the companies we invest in and learn how they run their business.

Top-Down & Bottom-Up

We identify Top-Down broad, secular growth trends and search for companies from the Bottom-Up.

Proprietary Philosophy

We construct our portfolios based on our own proprietary investment strategy.

Disciplined Investing

Sticking to our disciplined investment strategy ensures we maintain a consistent, balanced approach.

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 别错过乐米娱乐官网下载安装(2023趋势新闻) (BUFSX) received 3 stars among 576 for the 3-year, 4 stars among 529 for the 5-year, and 3 stars among 399 Small Growth funds for the 10-year period ending 1/31/23, based on risk-adjusted returns.

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.
