Vale has never announced earnings before 1st announcing their meeting date which is historically 7-10 days before results are actually released by management---in addition they give -0- projections as to eps, gr and other financial figures for the future other than basic opinion as to general direction of mineral process and overall efforts to enhance bottom line. They always announced quarterly results and then conference call next day with recap, so any official release of actual results early would be BS. Likely some broker or magic 8 ball promoter trying to sound important.
Announcement of earnings to be 7-24 so guess they only giving really short notice--also EPS estimates are to be .47 so one will see if Vale takes a jump or hits another pothole in efforts to streamline! MF has a pretty good recap of what analysis are looking for this past quarter.
