Buying corporate bonds in the secondary is complicated because dealing with corporate bonds is like trading in the stock market. Moreover, although prices of corporate bond constantly fluctuate there is not a quote system like there is for stocks.
The investor can opt to either invest in a bond mutual fund or by buy individual bonds. A bond mutual fund is akin to any other mutual fund with multiple bond issues contained in a single investment.
If the investor chooses to buy the corporate bonds directly, then careful evaluation of the bond is critically important. One has to examine the fund's performance over the last few years compared to the performance of similar funds. The investor must also learn to assess the worthiness of a company in terms of credits. There are professional rating companies that rank the corporate bonds. If the bond's ranking is low, obviously the risk factor is greater. Ratings are usually denoted by alphabets like AAA for High rating bonds and B or lower rating for junk bonds.
The pricing of bonds on the secondary market can be difficult to track and understand. Generally, an investor requests a quote for a specific amount of a specific bond or series of bonds. The broker or online system queries a bond desk which provides a buy or sell quote for the bond and amount specified. This quote is good for a limited amount of time and is known as a bona fide offer. The investor may then choose to accept the price or not.
