Bonds are very popular securities because they regularly pay interest income and pay back the initial principal after the bond matures. Bonds are popular with people of various risk classes but they certainly appeal to conservative investors looking for a steady income stream. Bond mutual funds may be even more attractive than buying into individual bonds because they provide a portfolio with increased diversification at a low-cost. Needless to say, before considering to purchase into a bond fund consider your risk tolerance, objectives, and income needs and compare that to the goals, risk level, and investment style of the bonds or bond funds you are interested in.
What is a Bond?
A bond is simply a loan between an investor and the bond's issuer. Say a company issues bonds and an investor can buy those bonds or in other words provide a loan to the company in return for a promise to pay back the initial investment after a specified period along with interest during the intervening period. The interest rate agreed upon by the company and the investor is called the coupon rate. When the bond matures or in other words when it's time for the company to pay back the loan, the issuer repays the investor's original investment.
Since bond markets generally don't move in tandem with equity markets, they can provide investors with the added diversification in their portfolios. Furthermore, they provide investors with a steady income stream. The only exception to this rule is for zero-coupon bonds, which from their name indicate that there are no interests rates attached to these bonds so there is no income paid out over time; however, even though zero-coupon bonds provide no cash flow they are sold at a discount to their face value and at maturity the investor gets paid the full face value of the bond.
There are many kinds of bonds available each having varying risks, benefits, tax implications to an investor's overall portfolio. Most bonds can be generally organized under four major categories: corporate, government, government agency, and municipal. Corporate bonds are issued by corporations and depending on the corporation that is issued them they can vary in risk. For instance, a small company issuing bonds can offer attractive yields to investors but can at the same time bring with it substantial amount of risk whereas a large-cap company can issue bonds that can be less risky because the investor knows that the chances of the large-cap company to default is slim. On the other hand, government bonds are probably the safest types of bonds because they are issued by the U.S. Treasury and backed by the credit of the U.S. government. Government agency and municipal bonds can vary substantially in risk but they typically fall between corporate bonds and government bonds on the risk spectrum.
Bond Mutual Funds
Many investors want the benefit of diversification to minimize their risk and they generally achieve this end by purchasing a bond mutual fund. This way investors can combine may different bonds into one portfolio and still pursue their fixed income objectives. Because bond funds aim to provide a steady income stream to investors, they are suited to investors that are looking to firstly minimize the impact of equity market fluctuations on their portfolios and secondly to protect their principal and current income. Bond funds may be the most appropriate for investors that are nearing retirement, are in retirement or others who do not easily tolerate fluctuations in the value of their portfolios. However, a bond fund is simply a pooled resource that invests in many bonds, so before investing consider the underlying individual bonds held in the portfolio particularly paying close attention the risk of those individual bonds and how that overall risk may affect the fund and your portfolio.
Risks
All bonds have come level of "credit risk," which is the risk that the bond issuer will go into default before the bond matures. In that instance, you may lose a portion or all your original principal and any income that may have been due. Bonds are often rated by Moody's and Standard & Poor's (S&P) to provide investors on the creditworthiness of the issuer; Aaa or AAA are the highest credit ratings given by these companies. Bond funds also can be issued ratings just like individual bonds based upon the quality of their underlying bond holdings.
Like stocks and other investments, bonds can have other risks from market fluctuations to an investor who is forced to sell them before their maturity date. If an investor is forced to liquidate his bond positions before their time and the bond's price has fallen at this time, he will lose part of his original investment as well as all future income from the interest. Another risk common to all bonds and bond funds is interest rate risk. Interest rates and bond prices have an inverse relationship, so when interest rates in the economy rise, the bond's price will generally fall and vice versa.
However, bond holders can avoid running the risk of fluctuating interest rates and market risk if they hold on to their bonds until maturity. On the other hand, bond mutual fund investors should consider these risks more carefully when purchasing into the bond funds they are interested in because fund managers can potentially buy and sell bonds as they see fit to meet the fund's objectives. As a result, interest rate risks and market risks become more prominent and therefore risk loss because of inherent fluctuations within the bond fund.
