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.

(As of 3/31/21) — The U.S. high yield sector continued its rally in the quarter, keeping yields at record lows. High yield bond prices continued their recovery from the COVID-19 sell-off in March 2020 amid stimulus and vaccine optimism. The high yield market, as demonstrated by the JP Morgan Domestic High Yield Index, posted positive returns in each month of the quarter (0.56% in January, 0.44 % in February, and 0.39% in March) maintaining yields at a 4.72% level. The 10-year U.S. Treasury Bond declined -7.08% during the quarter while the S&P 500 Index logged a return of 6.17%.

Following $3.4 billion in cash outflows in the final quarter of 2020, high yield mutual funds recorded another $10.2 billion in outflows this quarter. Interestingly, between the months of April to August 2020, high yield funds posted five consecutive months of inflows totaling $59.1 billion, which included the two largest monthly inflows ever recorded in April ($17.1 billion) and May ($20.5 billion), only to be followed by seven consecutive months of outflows totaling -$9.2 billion.

High yield new issuance volume was a record $158.6 billion during the three-month period after posting $99 billion in the previous quarter. Refinancing continued to be the primary use of proceeds accounting for ~77% of transaction volume in the quarter. According to JP Morgan, mid-tier and upper tier (B-split BBB) issues accounted for the bulk of activity in the quarter (86%) with the heaviest volume coming from Energy (20.3%), Gaming/Lodging (9.8%), and Telecommunications (6.8%).

The yield on the 10-year Treasury Bond increased 82 basis points (bps) during the quarter, from 0.92% to 1.74%, as early signs of inflation and a “return to normal” post-COVID outlook crept into the market. According to data from JP Morgan, the higher credit rating silos, which are more sensitive to interest rate movements, posted negative returns in the quarter while the lower tier silos performed better, as investors sought higher yields. The Defaulted segment produced the largest gain of 21.86% and the BB segment was the worst performer with a 0.09% loss.

According to data from JP Morgan, the U.S. high yield market’s spread to worst for the period was 406 bps, 38 bps tighter than the preceding December quarter and 194 bps tighter than its 20-year historical average of 600 bps. The yield to worst for the high yield market at quarter end was 4.72%, below the 20-year average of 8.34%, and essentially unchanged from the 4.71% at the end of the 4th quarter of 2020.


(As of 3/31/21) — The Buffalo High Yield Fund (BUFHX) increased 1.73% in the quarter, outperforming the ICE BofAML U.S. High Yield Index return of 0.90% for the three-month period. The Fund also outperformed the Lipper High Yield Bond Funds Index return of 1.47%.

During the period 112 out of the 143 issues in the Buffalo High Yield Fund produced positive returns. The three top contributors were Southwest Airlines 1.25% convertible bonds, J2 Global 1.75% convertible bonds, and Quad Graphics 7.00% corporate bonds. The rise in Southwest Airlines convertible bonds was driven by the underlying common stock rallying throughout the quarter as COVID-19 vaccinations began rolling out and interest in air travel picked up steam. J2 Global improved on the back of the underlying common stock increasing over 22% during the quarter, driven by better than expected earnings and continued demand for its cloud-based communication services. Quad Graphics corporate bonds returned to near par levels, after the company reported better than expected earnings during the quarter, and investors were attracted to its higher coupon, lower duration profile.


Guidewire 1.25% convertible bonds, Smile Direct Club zero coupon convertible bonds, and the Air Transport Services 1.125% convertible bonds were the worst performers during the quarter. Guidewire performed well in the December quarter and gave some of that back this period as investors rolled out of Technology and into value sectors. Smile Direct Club convertible bonds were issued during the quarter as the stock was peaking and then retreated after the issuance. Air Transport Services convertible bonds declined after the common stock peaked at year-end despite Amazon announcing that it was purchasing another eleven aircraft from the company.


(As of 3/31/21) — We are managing the Fund cautiously yet actively, focusing on high quality, below investment grade issuers with defensive business models and manageable credit metrics. 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. We ended the period with 143 positions, up slightly from the previous quarter’s level of 138 (excluding cash).

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 5 stars among 631 for the 3-year, 3 stars among 557 for the 5-year, and 4 stars among 355 High Yield Bond funds for the 10-year period ending 4/30/21.

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.
