On Monday, Pacific Investment Management Inc said investors yanked another $5.6 billion from its flagship Pimco Total Return Fund last month, bringing its assets to $110.4 billion at the end of April. Cash withdrawals in April marked the fund’s 24th consecutive month of net outflows. By comparison, the Vanguard Total Bond Market Index Fund had $117.3 billion as of April 30, according to a Vanguard spokesman. “We do not view this as an asset gathering horse race,” said John S. Woerth, spokesman at the Valley Forge, Pennsylvania-based Vanguard Group.
