How can you know if these morons are right?
Price up? Not supply and demand it's the Iran situation.
Price Down? Not supply and demand its the death of a terrorist.
What determines future prices is expected supply and expected demand. Period.
Good question.
How about this: "Stocks Fall Further on Rate Worries" http://biz.yahoo.com/ap/060608/wall_street_morning.html?.v=1
This is still supply and demand. Supply and demand of fungible products as it relates to pricing is not consumption and production amounts. It is the price versus quantity consumers are willing to buy and suppliers are willing to sell at the current market conditions. Just like as I might pay more for batteries living on the Gulf Coast before hurricane season. I will pay more to cover a perceived future risk. If I decide the risk is less, I won't pay as much.
