How is Bloomberg Professional service in terms of reporting realtime analyst upgrades/downgrades? Are they pretty fast? How difficult is it to weed through the tons of info coming across Bloomberg in order to discern the upgrades/downgrades from other news and act on them quickly? Does Bloomberg's UI provide filters so that you can get only the news you want to receive? Also, does anyone know if Bloomberg offers a trial of their service? Any insight would be appreciated!
