Markets are volatile this week...

Investors are going to the mattresses, stuffing their money away until they get better clarity on the Fed's intentions for interest rates.

Of course, the move hasn't been to actual mattresses but an intensifying push to money market funds, which have taken in $48 billion over the past four weeks and $212 billion in the second half of 2015, according to Bank of America Merrill Lynch. The $13.4 billion inflow over the past week marks the 10th-straight positive week, the longest streak since March 2008 for the $2.7 trillion money market industry.
