Bill Gross of PIMCO has increased holdings of mortgage backed securities issued mainly by Fannie Mae and Freddie Mac in Pimco's Total Return Fund. Holdings were 38% in Sept. 2011, holdings were 52% in Feb 2012. This bet on mortgage securities has enabled this bond fund to show a return of 2.88% in the 1st quarter of 2012. Mortgage bonds are doing well because of expectations that the Fed will setup another program to buy mortgage bonds because of a weak housing market in the U.S. In 2011 the Total Return Fund performance showed a 4.16% return compared to the Barclays Capital Aggregate Bond Index return of 7.84%. Gross has 37% in Treasurys in Feb. 2012. In 2011 Gross hurt returns by cutting back on Treasurys. He has also reduced exposure to emerging market debt and riskier corporate bonds. Holdings of high yield bonds were reduced by 1% to 3% in February 2012.
