Yellen is QE forever, but, may concentrate on MBS and the ten year only
which will make a mess of money markets. Meantime the dollar has climbed in yen term almost 25% in the past year, while wages are so "high" in China relative to India, folks are moving off shore manufacturing co's to the Muddle East.
The moment altering the mix of QE shows it's uneven head, the more mess the Fed will make of markets as a whole, and have to pull an Obungler routine similar to Health Care.
Problem is, impact will be profound as any other what the foo moment--with unknown consequences.
I suspect a few days of staring at that snake, where everyone is all content and no discontent, then Icahn or Soros, having positioned themselves short the market, will come out with ominous tones designed to Cramer it down our throats.
Silver and gold will do no better, especially since they are diluted by ETF, and now the new Tulip bubble, the bitcoin.
