The Heard on the Street column in the

Journal

takes a look at the recent bond trading of

Pimco

, which it said provided the spark for the bond market's recent turmoil. With the

Treasury Department

planning to sell fewer 30-year Treasury bonds going forward, and with the

Fed

raising interest rates, notable Pimco bond fund manager William Gross got an idea that proved to be quite profitable, the column said.

Because of those factors, Gross' idea was that the long bond could rally dramatically, while prices for shorter-dated Treasuries and riskier corporate and mortgage-backed bonds could remain depressed, according to the column. In a series of giant trades devised by Gross, his $180 billion portfolio bought huge amounts of long-term Treasuries and sold off mortgage bonds, surprising traders who expected Treasuries to remain depressed and roiling the market, the column stated. The column said Gross' strategy scored $200 million in profits.
