PowerShares Buyback Achievers Portfolio (NYSEArca: PKW)
Assets under management (AUM): $2.76 billion
Comment: Although PKW is nearly eight years old, it has really grown in prominence over the past year, hauling in $794.2 million of its $2.76 billion in assets under management. With an annual fee of 0.68%, PKW is a tad pricey compared to some plain vanilla broad market ETFs, so the ability to access the fund without paying commissions should prove attractive to some investors. It should be noted that PKW’s fee is not a deterrent. The ETF has established a cult following while outpacing the S&P 500 by 1,130 basis points over the past three years.
