As recently highlighted in P&I's annual look at money managers, PIMCO's 24% growth year-over-year in worldwide AUM to $1,242 billion was the highest of the 10 largest managers. Its long-term track record is equally if not more impressive. PIMCO's AUM stood at a mere $215 billion ten years ago. If PIMCO has the same success in the equity business which it had 18 months ago, other mangers' wallets are sure to shrink.
A detailed overview of PIMCO's AUM can be found in the P&I Research Center.
