As we have been pointing out since the beginning of the week, the one defining feature of the past 5 days has been a relentless short covering rally. And while the mechanics were obvious, one thing was missing: the reason. Well, courtesy of David Rosenberg's latest, we may now know what it is. Bottom line: for all who think that Bernanke is about to serve just Operation Twist next week... you ain't seen nothing yet. "The consensus view that the Fed is going to stop at 'Operation Twist' may be in for a surprise. It may end up doing much, much more." Rosie continues: "Look, we are talking about the same man who, on October 2, 2003, delivered a speech titled Monetary Policy and the Stock Market: Some Empirical Results. I kid you not. This is someone who clearly sees the stock market as a transmission mechanism from Fed policy to the rest of the economy. In other words, if Bernanke wants to juice the stock market, then he must do something to surprise the market. 'Operation Twist' is already baked in, which means he has to do that and a lot more to generate the positive surprise he clearly desires (this is exactly what he did on August 9th with the mid-2013 on- hold commitment). It seems that Bernanke, if he wants the market to rally, is going to have to come out with a surprise next Wednesday." In other words, stocks are now pricing in not just OT 2, and a reduction in the IOER, but also an LSAP of a few hundred billion. There is, however, naturally a flipside, to Bernanke's priced in announcement: "If he doesn't, then expect a big selloff." In everything, mind you, stocks, bonds, and certainly precious metals. And, of course, vice versa.
