I'm out and the reason I'm out is not so much the poor quarterly result but the way this announcement has been released . I was asking myself , sell or not and when I realized if I hadn't read HoTCopper this morning I could have missed it .
No announcement asterix under BLK on the ASX or ANZshare trading , it seems when you release something like this at 5.30pm it doesn't show up the next day , it looks to me like they were trying to hide something , at that point I lost faith and sold at a small loss .
