U.S. investors seem to be looking for a safe haven.

Financial Research Corp., Boston, has published data supporting that view in a report on May mutual fund net flows.

Stock and bond funds took in only $5.3 billion more cash than they lost in May, down from $18 billion in May 2005, according to FRC.

Meanwhile, money market funds are reporting $39 billion in net cash inflow for May, up from $24 billion for May 2005.

Investor interest in international and global funds continues to be strong but appears to be stabilizing. Those funds are reporting $10 billion in net cash inflow for May, up only slightly from a net inflow of $9.7 billion for May 2005.
