Schwab Emerging Markets Equity ETF (NYSEArca: SCHE)

AUM: $1.3 billion

Comment: For the emerging markets investor that counts every penny, it does not get any better than SCHE. Not only does Schwab waive commissions on this ETF, but with an annual fee of 0.14%, SCHE is also slightly less expensive compared to the rival Vanguard FTSE Emerging Markets ETF (NYSEArca: VWO).
