I'm new to investing/trading and I'm trying to understand analyst's influence on the stocks. Why their upgrades/downgrades matter so much? Is it because Institutions read and follow their recommendations? Or is it for retail investor like me? I always thought that Institutions move the stocks and trying to understand who do they listen to. Any comments? Also, if Institutions do follow it, do they get reports and upgrades/downgrades before us or at the same day.
