That's was my thinking too until I took a second glance. Markets look a little uneasy tonight and Asia, especially Hong Kong were weaker today. Maybe because China increased interest rates again? Gold is also smartly higher $625.90 cash on Kitco which is a heap better than the around $613.00 close last Friday.
I did notice that one or two days after Ahmadinejad wrote his letter to Bush, the stock market started falling rapidly back in May. I think that may have been some Arab money moving out of the market, leading to a quick, hard selloff in May. But then the market stabilized well in June/July, so I don't expect anything serious to happen any time soon.
