Sounds desperate to me, everyone on wallstreet and huge fortune 500 companies are so used to this free money that they know any small increase in rates will create a downward spiral in earnings moving forward, see how pathetic this game has become, QE 1 QE 2 QE 3 and 0% Rates have created this euphoria that these freebies will last forever which has become total addiction, it's a necessity now...as I have said before rates aren't moving up, they will keep them at 0% to feed the addiction even longer...
