U.S. junk-bond funds may see their biggest outflows in almost six months as investors pull back from risk on concerns about the spread of the coronavirus, Bloomberg News reported. High-yield funds are estimated to report an outflow of about $2.75 billion for the week ended Jan. 29, JPMorgan Chase & Co. analysts wrote in a note yesterday, citing Refinitiv Lipper data. That would be the biggest weekly outflow since the week ended Aug. 7 when investors withdrew more than $4 billion. Exchange-traded funds are expected to lead the withdrawals. Investors pulled close to $1.4 billion from the biggest junk bond ETF on Friday, the largest on record.
