Zeev - check the oil futures chart. Also compare the long term (inflation adjusted) cost of oil chart I posted last week. I think it is as simple as oil futures crashed, markets propelled up. Cheaper oil reduces chance of recession/depression. While markets still overvalued, cheap oil makes it more likely that bottom will be increasingly harder to peg. If Iraq not a quick battle and oil fields torched and oil futures up, market down. With cheaper oil, may have a long, slow sideways grind with dips and brief rally's.
