Vanguard Total International Bond ETF (NYSEArca: BNDX)
AUM: $760 Million
Comment: Vanguard usually does not roll out new products on a scale comparable to some of its rivals, so some of its new ETFs can fly under the radar. That can be said of BNDX, which does not grab a lot of headlines, but clearly has grabbed plenty of assets. Overall, Vanguard has pulled in 32 cents of every dollar allocated to ETFs this year, Bloomberg reported earlier this month. [Vanguard Keeps on Hauling in ETF Assets]
