Choosing Between Bonds And Bond Funds Splash image

Bonds play a role in a portfolio, even when the outlook for interest rates is uncertain. They offer a lower level of volatility than stocks. Plus, bonds have historically had different return characteristics. Determining how to best get exposure to them can be a challenge, however, as there are advantages and disadvantages to choosing between bond funds and individual bonds.

Bond funds offer ease and simplicity. A bond fund gives you instant access to a diversified portfolio of bond holdings. The downside is that the typical bond fund, unlike an actual bond, never matures. The price of a fund’s shares and the cash flows you receive will depend on the bond market’s fluctuations—which are influenced by changes in interest rates—and, of course, the manager’s skill. So, bond funds lack a guaranteed rate of return. Furthermore, with a bond fund you will pay ongoing annual management expenses and have no ability to control the timing of capital gains.

Bonds offer a higher (but not absolute) level of predictability. A bond held to maturity will provide a fixed rate of return. At a pre-specified date, you will get the face (“par”) value of the bond back, typically $1,000 per bond. In addition, you will receive semiannual interest (“coupon”) payments. Both of these amounts are fixed for traditional American bonds and enable you to calculate the pretax rate of return at the time of purchase. This rate of return does not alter as long as you keep the bond to maturity. This is why some bond experts suggest buying actual bonds as opposed to bond funds.

The key is to hold the bond until it matures. Individual bonds offer limited upside, but the risk of a complete loss of your invested capital on the downside. The primary upward drivers of a bond’s price are a decline in interest rates or a credit rating upgrade. Limiting the magnitude of the upside is the fixed return that bonds offer when held to maturity. Excessively overpay for a bond and you will lose money unless you can find someone willing to pay even more. The downside is the potential for losing your entire investment if a default occurs and there are not enough assets to repay you. (A bond is essentially a loan to the issuer.) Defaults tend to be limited among high-credit-quality bonds (though they can occur).

Bonds can be more difficult to buy than stocks. A single company may issue many bonds. Using General Electric as an example, the company has only one class of common stock that is publicly traded, GE. Conversely, a search on FINRA’s Bond Market Data website ( identified 500 bonds associated with General Electric. Thus, while you can call your broker and simply say “buy me X number of shares of GE stock,” you can’t do the same with GE bonds. You will have to give the CUSIP number (the bond equivalent of a stock ticker) or least the maturity or yield you desire. Since there are multiple issues, liquidity (the number of active buyers and sellers) will also differ. Depending on what you are trying to buy and the amount you are looking to invest, it may be challenging to complete a trade.

Thus, the decision as whether to buy a bond or a bond fund should be based not only on your goals, but also on the size of your portfolio, your personal preference about how involved you want to be with your portfolio and whether you want to work with a financial professional who is skilled in building and managing a bond portfolio.

Comparison of Bonds and Bond Funds


  • Fixed rate of return when held to maturity
  • Portfolio diversification depends on number and type of bonds purchased
  • Can be difficult to buy because of multiple issues and potentially low liquidity
  • Costs typically limited to brokerage commissions and taxes

Bond Funds

  • Rate of return dependent on market fluctuations and manager skill
  • Most funds offer simple access to a diversified portfolio
  • Easy to buy and sell through broker or fund company
  • Annual fees charged; investors have no control over timing of capital gains realized by fund

Bonds are a critical part of all portfolios, why don't you recommend a Model Bond Portfolio to compliment your Stock and Fund Portfolios? Right I could use guidance for a 50% Bond Portfolio.

The problem I have trying to buy individual bonds is knowing what a fair price is for the bond.

R Speir from FL posted over 2 years ago:

Model bond portfolio is a good idea.

H Mc allister from AR posted over 2 years ago:

There are so many different types of bond funds,ie;emerging mkts, short, intermediate, long term, intn'l,inflation protected, etc, that I would think it very difficult to create a model bond fund portfolio due to different investors age groups and investment objectives.
