Looking at Tokyo Stock Exchange is a waste of time!
Looking at Tokyo Stock Exchange is a waste of time because all big Citi news release is coming from the US. The news that would drive Citi up or down is coming from the US you fools! I know Tokyo is 14 hours ahead of NY but it means nothing.
You are incorrect on the whole. TSE has factored in all information including erroneous arbitrages, since C closed on NYSE Friday. If there are any further news releases between now and open in NY, those too would be factored in. It is correct that a lot can happen between now and opne in NY.
