Junk Bond Losses Top $35 Billion, JPMorgan Sees More

Junk bonds have fallen an average 3.9 percent this year, losing about $35 billion, according to data from Merrill Lynch & Co. indexes. Some funds managed by John Hancock Advisers LLC, OppenheimerFunds Inc. and Fidelity Investments are down more than 7 percent, showing that even the largest investors were caught off guard by the collapse.

While the Federal Reserve has slashed benchmark interest rates by 3 percentage points since September, it has been unable to get investors to increase their purchases of the riskiest assets. The declines are choking off financing for speculative- grade companies, boosting defaults.
