The news events this week will be any developments in the Greek sovereign debt situation, the FOMC decision on Wednesday (two day meeting) that may very well give the markets some insights into the nature of what will follow QE2, and of course the Russell 2000 rebalancing on Friday which may drive specific stocks as they move on and off the list.
Today was one of the lightest stock volume days of the year, so any moves may have an exaggerated affect on short term prices.
