European stocks are trading at multimonth highs as Germany's the constitutionality of the Fiscal Union and the European Stability Mechanism (ESM). However, it did state that the German liabilities were limited to the 190 billion euros ($243 billion) already pledged and that the German Parliament would have to explicitly approve any additional funds. This is effectively a cap on German participation, underlying the fact that this is not a "blank check."

The ESM should be functional in about a month.
