Vanguard Group has reduced the price of the Vanguard Emerging Markets ETF by 18%, Index Universe reports. The fund now costs 0.22% as compared to 0.27% previously. It has also cut expense ratios on five other ETFs as the move reflected greater efficiencies in the way it runs the funds. Vanguard, which had total ETF assets of $154.56 billion as of Feb. 24, 2011, has also rebranded four of its ETFs, adds MutualFundWire.
