Some combinations, think peanut butter and jelly or autumn and football, are tried and true. Others are just trying. At least that is the current state of affairs for emerging markets ETFs that hold high-yield bonds. Individually, emerging markets debt and high-yield have hit a rough patch. On Tuesday, the PowerShares Emerging Markets Sovereign Debt Portfolio (NYSEArca: PCY) hit a new 52-week low. In the past month, the SPDR Barclays High Yield Bond ETF (NYSEArca: JNK) is down almost 4%.

Things have not always been this hard for EMHY. The ETF debuted 14 months ago and has managed to rake in an impressive $248.5 million in assets. Perhaps surprisingly, the fund has not seen any outflows since the start of this month, according to Index Universe data.

EMHY’s timing when it debuted was good. The ETF came to market in the sweet spot of a fierce yield grab fueled by accommodating monetary policy from scores of central banks, the Federal Reserve included. Investors not only embraced EMHY for its stout yield, currently 5.42% on a trailing 12-month basis, but also for its capital appreciation potential.

Heavy allocations to Turkey and the Philippines ahead of those countries’ ascending to investment-grade credit ratings helped EMHY gain over 12 % from June 2012 through January 2013. Fast-forward to June 2013 and it is the very countries that helped lift EMHY (and other emerging markets bond ETFs) to prominence that are now hindering the fund.

At the end of the first quarter, Turkey and the Philippines were EMHY’s largest and third-largest country weights with allocations of 17.1% and 10.6%, respectively, according to iShares data.
