Investors pulled $4 billion out of long-term stock funds in November, according to Morningstar. That brings the total outflow to $67.7 billion for the year.

Investors also fled municipal bond funds, taking out $7.6 billion. That broke a string of 22 consecutive months of inflows.

And they were wary about other bond funds. Only $6.0 billion went into taxable-bond funds, down from $21 billion coming in in October.

Money market funds, which gained $24.7 billion,  their best month since January 2009, according to the mutual fund reporting firm.

Outside the U.S., world-bond, bank-loan, emerging-markets bond and multisector bond funds gained. This group collected a combined $7.4 billion in November, even though another member of the "risk on" group--high-yield funds--saw outflows of $1.0 billion.
