NEW YORK ( Fabian Capital Management) -- The volatility in interest rates this year has been particularly troublesome for fixed-income investors.Much of the jump in long-term Treasury bond yields has been due to the expectation of the Federal Reserve tapering its asset purchase programs in 2013. The unrelenting rise in stock prices combined with investors pouring assets into equity-oriented funds at a breakneck pace has also put downward pressure on the fixed-income sector. The recent municipal bankruptcy headlines in Detroit certainly haven't helped matters either. These factors have combined to create a panic situation in Treasury bond prices that has sent long-duration ETFs such as the iShares 20+ Year Treasury Bond ETF ( TLT) to new lows last week. TLT is currently down over 14% from its May 2013 high and appears to be headed lower.
