The U.S. Purchasing Manager’s Index for the month of August was released earlier today and the numbers show continued signs of expansion hitting its fastest pace since March 2013 and the highest reading in more than four years, this according to a story on The index climbed to 57.9, barelypurchasing managers index rose yet again shy of the 58 that most economists had expected.

Even the relatively rosy expectations show that many are beginning to believe the U.S. economy is indeed on track to recover, although it somehow doesn’t seem like it. Any reading above 50 indicates a growing economy. The Dow may have paid some attention to the news as it finished off slightly to 17067.56 while the S&P stood tall yet again above the 2000 mark at 2002.28.

Investors who track mortgage bonds, that which mortgage rates are tied, are expecting a jump soon but it appears very few investors are taking any chances to dump bonds and get back more heavily into stocks. It’s getting very, very close to the ultimate demise of QE when the Fed stops the printing presses and once that settles into the minds of investors it really only takes a few institutional bond holders to start a mortgage bond selloff and watch low rates fly out of the real estate window.

Consistently positive, albeit somewhat tepid at times, economic reports such as the purchasing manager’s index released today along with the realization that rates can’t stay low forever might actually nudge the credit and stock markets back into its more traditional paradigm—good economic news, higher rates.
