High-yield corporate bond ETFs have been among the top-selling funds in 2012 after enjoying gains of more than 20% the past year.

The iShares iBoxx High Yield Corporate Bond (NYSEArca: HYG) and SPDR Barclays Capital High Yield Bond (NYSEArca: JNK) have gathered year-to-date inflows of $5.8 billion and $2.9 billion, respectively.

They are the two largest junk bond ETFs and are paying dividend yields of about 7%.

“So much money has flooded into the junk-bond market from yield-hungry investors that weaker and weaker companies are able to sell bonds,” The Wall Street Journal reports. “Credit ratings of many borrowers are lower and debt levels are higher, making defaults more likely.

Inflows to high-yield bond funds have climbed to a record this year at $34 billion, the newspaper says.
