Turmoil in Bond Funds Starts to Subside

The universe of bond mutual funds -- churned for months by the credit crunch, the mortgage mess, prospects of stagflation, threats to state-tax exemption of muni bonds and the auction-rate securities mess -- has shown signs of finally calming.

At least that's the indication from the latest summary of major changes in TheStreet.com Ratings bond fund grades.

The brevity of the accompanying table of major changes speaks volumes about the move toward a tranquil environment for bond funds.

Only a single open-end bond fund, the RidgeWorth Limited-Term Federal Mortgage Fund(SLTMX Quote - Cramer on SLTMX - Stock Picks), experienced a major upward revision in the latest computations of TheStreet.com Ratings gradings of bond funds.

SLTMX rebounded from the lowest possible mark of E-minus, which equates with a sell recommendation, to C-plus grade, which makes the fund a hold recommendation, one notch below a buy classification.

Similarly, only five bond funds suffered major downgrades.

Given the growing uncertainty about the economy, it shouldn't be a surprise that a pair of high-yield bond funds suffered major downgrades.

The Pioneer High Yield Fund(TAHYX Quote - Cramer on TAHYX - Stock Picks) was demoted from a C-minus to a D-minus, which pushed its recommendation from hold to sell.

The SunAmerica High Yield Fund (SHNAX Quote - Cramer on SHNAX - Stock Picks) tumbled from a D-plus to an E-plus, which pushed it from a weak sell to a strong sell.

The AMF Ultra Short Fund (AULTX Quote - Cramer on AULTX - Stock Picks) was hammered 14.44% over the past three months that left it down 13.85% over the past year and resulted in a downgrade of D to E-minus. The fund has been loaded with mortgage paper and has recently had investments in troubled Fannie Mae obligations, failed IndyMac and Bear Stearns obligations as well as Washington Mutual notes.
