I for one am very suspicious about a rate hike of 25 tomorrow. The action in some of the commodities has been very different over the last several sessions, I have seen quiet liquidation going on especially in natty. Also note the lack of VIX getting bid up although we have been selling off. TSO calls for July ATM's today went nuts.
Maybe paranoid thinking but these trades are indicative of a shock and awe rate hike that would crush commodity complex and run the dollar (initially anyway). Call it an initial stab at inflation and an experiment on Bernanke part to test the waters.
Bottom line is cheap money will not spur growth in this particular environment, but cooling off of inflation will considerably help the consumer. IF this were to transpire tomorrow, I would expect a knee-jerk reaction sell-off of equities, followed by a very strong rally (either at the end of the session or on Thursday).
