Bernake has already indicated that he will do ANY and AS MUCH QE as is required (and European Central Bankers are mostly of the same general mindset).

The ONLY situation that will overcome Bernake's QE mindset and action is an "Out of the Blue" event, or series of events, that runs past the ability of the Fed to quickly compensate for ... ie:

*a big player blowing up such as AIG and Lehman in 2008 which then brought down lots of other players and shined a light on the termite riddled system;

*a 9/11 style major league terrorist event;

*a major earth / natural / or man disaster event;

*an outbreak of a major conflict event;

*an oil availablity or pricing event;

Baring a major league outside event occuring I would look for a continuation of the same as now and wouldn't count on normal market forces being at work.

As Marty Zweig put in his classic book about markets and trading nearly 40 years ago ... "Do NOT fight the Fed!!" (I think that was his Rule 1, his Rule 2, and his Rule 3)
