PIMCO Total Return Holding 52% in "Cash" Says Bloomberg article. Citing PIMCO's website, a recent Bloomberg article said, "Cash equivalents including debt maturing in less than a year accounted for 52 percent of the assets of the $103 billion fund as of May 31, up from 48 percent in April, the latest data posted on Pimco's Web site show." While we're not sure yet what kinds of "cash equivalents" Gross's fund holds, its approximately $53.5 billion in cash holdings would rank it as the fifth largest money market fund portfolio were it a standalone fund.
