QUOTE (from that CNN article): "There's a lot of nervousness that Greece could default this weekend, and Greek bonds yields keep rising," said Joe Saluzzi, co-head of equity trading at Themis Trading. Reports said Germany is preparing to shore up its banks to protect them against a Greek default. If Greece's bonds become worthless, that can trigger capital-requirement problems, and a lot of major banks could go under, Saluzzi said. "The financial contagion could be pretty bad, so investors are getting out now and waiting to see how all of this will shake out," he added."
Keep an eye out this weekend, whether on the foreign financials or the 9/11 anniversary....
