NEW YORK — Brace yourself. If you have money in a bond mutual fund, you're likely to feel some pain when you open your mid-year account statement.
After years of steady returns, many bond mutual funds have suffered losses this year. Some of the sharpest drops are in funds that buy Treasury bonds, and it could be a rude awakening for investors lulled into thinking Treasurys were among the safest investments.
A look at how other mutual-fund categories performed during the first half of 2013 shows other clear losers, as well as winners. Mid-year is often a time when investors check on their portfolios, but it's important to only make adjustments that are in line with your investment goals.
"While performance can give you a guide as to how a fund or ETF has done, it's not gospel," says Todd Rosenbluth, director of ETF and mutual fund research at S&P Capital IQ. "You should not chase performance. You should use it as one of the tools to help you sort through the investment universe."
Among the biggest losers of the first half of 2013: mutual funds that own long-term government bonds, like 30-year Treasurys. They lost an average of 10 percent through Wednesday, according to Morningstar. That follows returns for the category of 3.9 percent in 2012, 32.9 percent in 2011 and 11.7 percent in 2010.
Demand for bonds has declined because of concerns that the Federal Reserve may ease up on its bond-buying economic stimulus program. Chairman Ben Bernanke said that the central bank may slow its purchases later this year and halt them altogether by mid-2014.
The drop in demand has forced prices down for bonds. The price decline has been more than enough to wipe out the regular interest payments that bonds make. When a bond's price falls, its yield rises, and a 30-year Treasury bond yielded 3.57 percent on Wednesday. That's up from a low of 2.83 percent on May 1.
"You don't need a big move in bonds to eliminate a whole year's worth of income," says Mark Spellman, manager for the Value Line Income and Growth fund, which has a four-star rating from Morningstar.
