Beginner's Guide to Corporate Bond Mutual Funds

The corporate bond market is one of the largest markets in the world, worth $9.77 trillion, or nearly 25% of the entire U.S. bond market as of the start of 2014. Corporate bonds are appealing as they are considered safer than stocks and they pay higher interest than government bonds.

Corporate bonds can be divided into two types: investment grade and junk (otherwise known as high yield securities), which is arguably the most important choice when determining a portfolio of corporate bonds. These two types of corporate bonds can be broken down further into short-, medium- or long-term and can be broad-based, domestic, foreign, or sector specific.

Junk bonds, those rated BBB- and lower, have a higher risk of default, but they pay higher yields than investment grade corporate bonds. Regardless of the type, corporate bond mutual funds allow for investors with smaller portfolios to gain exposure to this asset class, and can provide a well-diversified high yield corporate bond portfolio at a low cost.

How Corporate Bond Funds Can Be Used in a Portfolio

Corporate bond funds are a great choice for investors seeking yields higher than government bonds that are still relatively safe. They can be bought and sold using a regular brokerage and give exposure to this particular asset class. As with any investment, there are risks involved. Corporate bond funds have higher expense ratios than a comparable stock mutual fund.

With an individual bond, risk decreases the longer you hold the security, but this is not true with corporate bond funds because the individual holdings are constantly maturing, being bought and sold. There are many different kinds of corporate bond funds with different risk/return profiles that can cater to a variety of different investor appetites.

Types of Corporate Bond Funds

There are a variety of different types of bond funds:
  • Broad-based: These cover a variety of different corporate bonds, everything from investment grade to junk, domestic and foreign. These are good for investors wanting a little bit of everything that corporate bond funds have to offer.
  • Domestic: Those originating from an investor’s home country.
  • Foreign: This includes bonds that are issued and traded outside the country in whose currency they are denominated, and U.S. dollars held by foreign institutions outside the United States. These can include eurobonds and eurodollar bonds.
  • Sector Specific: As there are many different types of corporations, investors can buy bond funds in corporations in specific sectors, such as energy.

Benefits of Owning Corporate Bonds with Mutual Funds

Corporate bond mutual funds offer diversification to an investor’s portfolio and require a low minimum investment. There are no upfront sales commissions or redemption fees either. It is easier to construct a corporate bond portfolio by purchasing a single mutual fund than it is to do research on the same number of corporate bonds that the mutual fund consists of along with managing the maturity date of different bonds.

Furthermore, bond mutual funds never mature like a single corporate bond would; as corporate bonds mature within the portfolio they are replaced with others. Another benefit is that corporate bond mutual funds give you access to the expertise of a portfolio manager. With these benefits, investors looking to gain exposure to corporate bonds should at least consider a corporate bond mutual fund.

Tax Considerations

If an investor owns bonds that generate taxable income, then that investor will be taxed on that income in the year it’s received. Since fund managers regularly buy and sell bonds, there may be capital gains involved, in addition to taxation on the interest received. Income from corporate bond funds are generally taxed at the federal and state level at the investor’s ordinary income tax rate; capital gains taxes can be eligible for a reduced capital gains rate. Like other investments, the tax owed on corporate bond funds can be deferred if an investor holds the investment in a retirement account such as a 401(k).
