Back in August, I wrote an article that is worth reviewing if you are invested in bonds, Rising interest rates are forcing bond values down. The forecast in that article is reinforced by the fact that bond mutual fund withdrawals are having a record year in 2013.
Why do you think that is? Simple - many investors fear that market interest rates will start rising, thereby forcing the value of bond portfolios down. So, some of these investors are taking their money out of bonds by withdrawing like crazy from bond mutual funds.
Recent action by the Federal Reserve also reinforces the trend. The Fed stated that it would begin "easing" their monthly buying of Treasury securities. In simple terms, they are signalling that they will let market interest rates rise over time.
So, if you are invested heavily in bonds, I once again encourage you to look at the situation carefully and talk to your financial advisor. You may need to look at other investment options.
