Active ETFs

PIMCO Total Return ETF (NYSEArca: BOND) experienced net outflows in May for the first time but the bond giant still rules actively managed exchange traded funds with control of more than half the market share.

At the end of May, PIMCO managed seven active ETFs with total assets of $8.5 billion, or a market share of 58.7%, according to data from AdvisorShares. BOND, listed in March 2012, holds nearly $5 billion by itself. [BOND Sees May Outflow]

WisdomTree Investments (NasdaqGM: WETF) oversees 13 active ETFs with about $3.5 billion and AdvisorShares manages 18 funds with about $829 million total. There are 13 firms that offer active ETFs in the U.S.

Most ETFs are passive products designed to track indices. For example, active ETFs account for assets of $14.5 billion of a roughly $1.5 trillion business — a tiny fraction.

However, more ETF firms and mutual-fund managers are filing to introduce active products. [More Actively Managed ETFs are on the Way]
