Investors pulled $859 million from U.S. high-yield bond funds this week, the largest withdrawal since the period ended Oct. 1, according to Lipper.

That brought net outflows for the year to $14.4 billion.

Investors also withdrew $511 million from U.S. funds that buy leveraged loans, increasing net outflows for that asset class to $16.6 billion in 2014, Lipper data show.
