Comment: BNDX is the cheapest international-focused bond ETF, tracking a diversified portfolio of investment-grade government, corporate and securitized fixed-income investments issued in local currencies. However, the ETF employs a currency-hedge to mitigate any negative effects of depreciating foreign currencies. BNDX has a 7.0 year duration and a 1.05% 30-day SEC yield.
