A recent ranking of the top 300 money managers in the U.S., confirms the postion of Fidelity Investments at the top of the heap.

In the survey by Institutional Invetor magazine, Fidelity holds the number one position with $886.4 billion under management, although this is down from $915.6 billion the previous year. (All figures in U.S. dollars.)

That is certainly enough to keep Fidelity ahead of number two player, Barclays Global Investors, which has $801 billion under management, slightly ahead of the previous year’s total.

State Street Global Advisors continues to hold the three spot with $724.5 billion under management, up notably from $674 billion in the prior year. The big newcomer is J.P. Morgan Fleming Asset Management, which jumped from 13th place to fourth in the wake of its merger with Chase, which saw it almost double its asset base to $637.8 billion.

J.P. Morgan’s rise comes at the expense of Merrill Lynch Asset Management, which slides to fifth spot. Its asset base remained flat at $556.7 billion.
