The Bill Gross-led PIMCO Total Return Fund
Gross' fund has had investor redemptions on and off for more than year. Morningstar estimates that total redemptions from the $241 billion Total Return Fund have exceeded $13 billion since November 2010.
Still, this past December was kinder to Gross than the previous year. In December 2010, Morningstar estimates investors withdrew $6.7 billion from the PIMCO flagship fund.
