Is the ex-dividend date linked to the time zone of the market it is bought at? Let's imagine an American firms stock traded at NASDAQ and a German market, the ex-Dividend day being the 1st February. This announcement is made on their American website, without specifying a time zone. I want to get the dividend.
1) The German market opens at 8am on February 1st local time, which would be 2am on February 1st New York time. I sell my shares at 8am. So the trade would have been made on ex-dividend day, with NASDAQ being closed. Will I get the dividend?
2) Let's imagine a bigger time difference, where the market I sell the stock is 8am in the morning of February 1st local time, but New York Time is sill 11pm on January 31. Will I get the dividend?
Or phrased differently, is the Ex-dividend linked to a date, independent of time zones, or is it linked to a local time zone?
