Why bond mutual funds?

I have reported that bond mutual funds have been getting the majority of new dollars from fund investors, according to Strategic Insights. So what are the expectations from a portfolio of corporate bonds. Here are a couple of charts from the St Louis Federal Reserve illustrating current yields on two types of bonds, high quality (Moody's AAA) and medium quality (Moody's BAA).

As you know, bond yields and prices move in opposite directions to each other. So as yields have come down, prices have moved up. And many would say that the opportunity for big double digit returns from bond funds, as we have recently enjoyed, is a once in a lifetime opportunity. These graphs seem to illustrate that too. As you can see, yields have dropped to near recent historic low levels, not leaving much hope for still lower yields and higher prices. In this environment, mutual funds that use a buy and hold strategy can expect no more than the coupon (dividends). On the other hand, funds that employ trading strategies to take advantage of apparent mispricing could add to the total return of the fund. Scanner
