active/managed etfs

interesting ref on active/quant managed etf families here. 'One example is the PowerShares FTSE RAFI US 1000 Portfolio ( PRF | Quote | Chart | News | PowerRating), which applies a fundamental weighting approach to the 1,000 largest U.S. equities. The index provider, Research Affiliates LLC of Pasadena, CA, has become widely known for its fundamental indexing. Chairman Robert Arnott has observed that equally weighting a given index of stocks historically adds about 180 bps/yr of return versus market cap weighting, and fundamental weighting tacks on an additional 80 bps/yr above equal weighting.'
