Bond Funds

August 6, 2025

Bond funds are investment vehicles that pool money from multiple investors to purchase a diversified portfolio of bonds. These funds can vary significantly in terms of risk, yield, and the sectors they invest in.

Bond Ratings

Bond ratings help investors assess the credit risk of a bond — that is, the likelihood the issuer will default. The two main rating agencies are:

Standard & Poor’s (S&P): Ratings range from D (lowest) to AAA (highest).

Moody’s: Ratings range from C (lowest) to Aaa (highest).

Types of Bond Funds

1. Investment-Grade Bond Funds

Composition: These funds primarily invest in corporate bonds rated BBB/Baa or higher. They may also include:

U.S. Treasury securities

Mortgage-backed securities

Maturity Range: Typically 10 to 30 years.

Risk Level: Lower risk — these bonds are issued by financially stable companies or government entities, making defaults less likely.

Investor Appeal: Suitable for those seeking a higher yield than U.S. Treasury funds, but still desiring relative safety and reliability in interest and principal payments.

2. High-Yield Bond Funds (Junk Bond Funds)

Composition: These funds invest in:

Bonds rated below BBB/Baa

Non-rated bonds

Risk Level: Higher risk — these bonds are issued by less financially stable entities, increasing the risk of default.

Return Potential: Higher yields than investment-grade funds, due to the added risk.

Investor Appeal: Attracts investors willing to take on more risk in exchange for potentially higher returns.
