What is the life span of these alerts. A day, a week, a month? More ofen than not, these changes are made at the top for upgrades and at the bottom for downgrades, unless there is a fundamental reason that is obvious. I guess as the saying goes "You Get What you paid for it". I just don't believe that the analyst give the information for free. What do the smart traders believe. Comments welcome, lets just try and avoid poltics. Thanks.
