This ETF offers access to junk bonds from emerging markets issuers, an asset class that is generally excluded from long-term portfolios, but that has the potential to deliver impressive risk-adjusted returns. Most bond portfolios are dominated by holding in high quality debt of U.S. issuers. As such, HYEM offers unique exposure in two regards; it focuses on junk bonds of companies headquartered in emerging markets. As such, this ETF has the potential to bring geographic and currency diversification to a fixed income portfolio while also delivering returns materially higher than those on investment grade debt. HYEM focuses on U.S. dollar-denominated debt, which removes the foreign exchange rate risk from the equation. There are a number of other emerging markets bond ETFs that include currency exposure (such as ELD), though they generally include exposure to corporate as well as sovereign debt. HYEM offers similar exposure as EMHY for a fraction of the cost, increasing its appeal among cost-conscious investors.
