The certainty trap | Fixed income market commentary 2Q 2026

June 30, 2026

Lately I’ve found myself reading more history than fiction. What keeps pulling me back isn’t the history itself. It’s the timeless lessons about how thoughtful leaders make decisions when the stakes are highest and every option appears unattractive.

I recently finished One Minute to Midnight, Michael Dobbs’ account of the Cuban Missile Crisis. What struck me wasn’t how close the world came to nuclear war. It was how quickly the debate became framed as a binary choice: invade Cuba or accept Soviet nuclear missiles ninety miles from Florida.

Important Disclosures

This material is not intended to be a recommendation or investment advice, does not constitute a solicitation to buy, sell or hold a security or an investment strategy, and is not provided in a fiduciary capacity. The information provided does not take into account the specific objectives or circumstances of any particular investor, or suggest any specific course of action. Investment decisions should be made based on an investor’s objectives and circumstances and in consultation with his or her financial professionals.

The information, data, analyses, and opinions presented herein (including current investment themes, the portfolio managers’ research and investment process, and portfolio characteristics) are for informational purposes only and represent the investments and views of the portfolio managers and Harris Associates L.P. as of the date written and are subject to change and may change based on market and other conditions and without notice. This content is not a recommendation of or an offer to buy or sell a security and is not warranted to be correct, complete or accurate.

Certain comments herein are based on current expectations and are considered “forward-looking statements.” These forward-looking statements reflect assumptions and analyses made by the portfolio managers and Harris Associates L.P. based on their experience and perception of historical trends, current conditions, expected future developments, and other factors they believe are relevant. Actual future results are subject to a number of investment and other risks and may prove to be different from expectations. Readers are cautioned not to place undue reliance on the forward-looking statements.

Yield is the annual rate of return of an investment paid in dividends or interest, expressed as a percentage. A snapshot of a fund’s interest and dividend income, yield is expressed as a percentage of a fund’s net asset value, is based on income earned over a certain time period and is annualized, or projected, for the coming year.

Investing involves risk; principal loss is possible. There is no guarantee the Fund’s investment objective will be achieved.

Fixed income risks include interest-rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments. Bond values fluctuate in price so the value of your investment can go down depending on market conditions.

The Oakmark Bond Fund invests primarily in a diversified portfolio of bonds and other fixed-income securities. These include, but are not limited to, investment grade corporate bonds; U.S. or non-U.S.-government and government-related obligations (such as, U.S. treasury securities); below investment-grade corporate bonds; agency mortgage backed-securities; commercial mortgage-and asset-backed securities; senior loans (such as, leveraged loans, bank loans, covenant lite loans, and/or floating rate loans); assignments; restricted securities (e.g., Rule 144A securities); and other fixed and floating rate instruments. The Fund may invest up to 20% of its assets in equity securities, such as common stocks and preferred stocks. The Fund may also hold cash or short-term debt securities from time to time and for temporary defensive purposes.

Under normal market conditions, the Fund invests at least 25% of its assets in investment-grade fixed-income securities and may invest up to 35% of its assets in below investment-grade fixed-income securities (commonly known as “high-yield” or “junk bonds”).

The Oakmark Equity and Income Fund invests in medium- and lower-quality debt securities that have higher yield potential but present greater investment and credit risk than higher-quality securities. These risks may result in greater share price volatility. An economic downturn could severely disrupt the market in medium or lower grade debt securities and adversely affect the value of outstanding bonds and the ability of the issuers to repay principal and interest.

The Oakmark Equity and Income Fund’s portfolio tends to be invested in a relatively small number of securities. As a result, the appreciation or depreciation of any one security held by the Fund will have a greater impact on the Fund’s net asset value than it would if the Fund invested in a larger number of securities. Although that strategy has the potential to generate attractive returns over time, it also increases the Fund’s volatility.

Oakmark Equity and Income Fund: The securities of medium-sized companies tend to be more volatile than those of large companies and have underperformed the securities of small and large companies during some periods.

These and other risk considerations such are described in detail in the Fund’s prospectus.
