"Super Thursday

European and Asian stocks, as well as S&P futures were little changed ahead of "Super Thursday's" events which include the U.K. general election, Comey's testimony and the ECB policy decision. That however may change following a Bloomberg news report that the ECB is set to cut inflation forecasts through 2019 due to weaker energy prices, suggesting the "hawkish" ECB announcement some had expected tomorrow has been postponed.

With traders realizing that the "Thursday Turmoil Trifecta" looms, world stocks dropped and safe-haven assets rose as investors focused on the growing tension in the Middle East, while caution spread across markets in a week full of risk events including James Comey’s congressional testimony to the ECB’s policy meeting and Britain’s increasingly uncertain election, all in the span of 24 hours. As a result, European and Asian stocks as well as S&P futures all fell, while gold, yen and Treasuries gained.
