Th very best place I have found to get up to the minute news bulletins on any company is, no` 1 the Newspaper, Globe and Mail business section [money and markets] , 12:30 am on until opening bell.
During the day Yahoo Canada or United States, Pink Sheets site, or Nasdaq site, generally I have all on my page at all times, bouncing around . The thing I find so usefull is that newspaper info pre market, that will many times lead one right into watching companys all day, many times these companys post major bulletins after the closing bell, then it hits the newspaper for next day, as well Yahoo picks them up also, the after the closing bell bulletins that is. Another is P.R. news wire, it is for journalists but many times on the front page you will get info.
