The equities with the highest fundamental strength are weighted according to fundamental scores.

"The PowerShares fundamentals weighted ETFs are an important alternative to cap weighted portfolios seeking to provide investors higher returns with lower volatility over time. We are pleased to continue our industry leading role and will be lowering fees across the entire domestic FTSE RAFI lineup," continued Bruce Bond.
