Fund Objective & Investment Process

The investment objective of the Buffalo High Yield Fund is primarily current income, with long-term growth of capital as a secondary objective. The High Yield Fund normally invests at least 80% of its net assets in higher-yielding, higher-risk debt securities rated below investment grade by the major rating agencies (or in similar unrated securities), commonly known as “junk bonds”. Debt securities can include fixed and floating rate bonds as well as bank debt and convertible debt securities.

While the Fund maintains flexibility to invest in bonds of varying maturities, the Fund generally holds bonds with intermediate-term maturities. With respect to the remaining 20% of the Fund’s net assets, the Fund may invest in investment grade debt securities, U.S. Treasury Securities (typically with maturities of 60 days or less), money market funds, and equity investments, including dividend paying stocks and convertible preferred stocks.


Our team brings many years of credit research experience to the bond market. We are proud to have provided our shareholders with what we believe is a conservative approach to investing in high yield bonds since 1995.

All ratings are as of 6/30/21. Moody’s is the rating source for the Quality Breakout Table. A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO), such as Moody’s or Standard & Poor’s. The firm evaluates the of credit worthiness of an issuer with respect to debt obligations, including specific securities, money market instruments, or other bonds. Ratings are measured on a scale that generally ranges from Aaa (highest grade) to C (lowest grade); ratings are subject to change without notice. Unassigned rating indicates that the debtor was not rated by an NRSRO and should not be interpreted as indicating low quality.

(As of 6/30/21) — The U.S. high yield market continued its positive return streak in the quarter, posting its fifth consecutive positive quarter, after suffering a significant correction in the March 2020 quarter driven by the COVID-19 outbreak and plunging crude oil prices. In fact, high yield bond yields posted record lows in June, hitting 4.30% as investors seemed willing to believe the Federal Reserves’ claim that inflation will prove transitory. The 10-year Treasury Bond returned 3.26% during the quarter while the S&P 500 Index posted a return of 8.55%.

Despite the positive returns, high yield funds experienced a cash outflow of $3.2 billion in the 2nd quarter. Meanwhile, high yield issuers brought the third-highest quarterly volume of new issuance on record with $140.5 billion, which followed the $158.6 billion issued in the preceding quarter. According to JP Morgan, split BBB and BB-rated issues accounted for the bulk of activity (42%), and new issuance was tilted heavily toward Energy (11.4%), Health Care (9.7%), and Services (9.5%).

During the quarter, the 10-year Treasury Bond’s yield fell 27 basis points (bps) from 1.74% to 1.47%, reversing a third of the 82 bps increase in the 1st quarter. Every sector in the U.S. high yield universe and every credit rating silo produced positive returns during the period. According to data from JP Morgan, the higher and lower quality ends of the high yield credit spectrum outperformed the split BB/B rated credits, with the lower split B/CCC segment performing the best at 3.90% and 3.31%, respectively. The split BB segment was the laggard with a smaller gain of 2.46%.

According to data from JP Morgan, the U.S. high yield market’s spread to worst for the period was 370 bps, 36 bps tighter than the preceding quarter and 225 bps tighter than its 20-year historical average of 595 bps. The yield to worst for the high yield market at quarter end was at an all-time record low of 4.30%, well below the 20-year average of 8.24%, and below the yield of 4.72% at the end of the prior quarter.


(As of 6/30/21) — The Buffalo High Yield Fund (BUFHX) produced a return of 2.52% for the quarter but slightly trailed the ICE BofA U.S. High Yield Index and the Lipper High Yield Bond Funds Index, which both gained 2.77% during the quarter.

During the period, only 12 out of 148 issues in the Buffalo High Yield Fund produced negative returns. The top three contributors were Nuance Communications 1.5% convertible bonds, Northern Oil & Gas 8.125% corporate bonds, and Mitek Systems 0.75% convertible bonds. In early April, Microsoft announced the acquisition of Nuance for a 23% premium, driving the strong performance in Nuance convertible bonds. The Northern Oil & Gas bonds, along with the Energy sector as a whole, improved on the back of the 24% rally in West Texas Intermediate crude oil during the quarter, as the COVID-19 vaccinations roll-out increased travel demand. Mitek Systems convertible bonds performed well after beating quarterly expectations and the announced acquisition of ID R&D, a provider of biometric identity fraud software, in early June.


The Southwest Airlines 1.25% convertible bonds, Air Transport Services 1.125% convertible bonds, and the Lumentum 0.50% convertible bonds were the worst performers during the quarter. Southwest Airlines convertible bonds were the top performer in the preceding quarter, and gave some of that back near the end of this quarter, after the CEO announced he would be stepping down in 2022. Despite Amazon exercising warrants to increase its stake in Air Transport Services to 20% early in the quarter, the convertible bonds declined in conjunction with the common stock, after the company reported that Department of Defense traffic through its Omni Air division was lighter than analysts expected. Lumentum convertible bonds were negatively-impacted after several peer Apple suppliers missed estimates and Lumentum then posted its own disappointing quarterly results.


(As of 6/30/21) — We are monitoring the ongoing recovery from the COVID-19 pandemic and the Federal Reserve’s responses to emerging inflation, which will hopefully return to normal later this year and into 2022. The potential for new regulatory changes to various industries from the Biden administration is another area of focus. We are managing the portfolio cautiously yet actively, maintaining our ongoing bias for high-quality issuers with defensive business models and manageable credit metrics. We ended the quarter with 148 positions, up slightly from the previous quarter’s level of 143 (excluding cash). We will continue to deploy cash in opportunities that we believe offer the most appealing risk/reward tradeoff with a bias toward shorter durations and less levered credits. Additionally, we believe bank loans offer a more defensive position as they provide senior positioning in the capital structure and less interest rate sensitivity due to their floating rate structures. Finally, we continue to look for opportunities in convertible bonds and preferred stocks.

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 High Yield Fund (BUFHX) received 4 stars among 625 for the 3-year, 4 stars among 548 for the 5-year, and 4 stars among 357 High Yield Bond funds for the 10-year period ending 8/31/21.

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.
