Hi Andy,
It's not sixth sense but based on the history. When you checked the half year account in 2006-2009, the accouncement day was 16th March. in 2008, it's 12th March because 16th March is weekend. That's the way I worked it out. Let's see tomorrow. History also said the ann would be after market around 5pm. That's why I didn't damp any despite of the depth, only one day to go. GL to us.
