They made it easy for the uneducated investor to invest in companies that see the spotlight on the news. You can invest in minutes and for free now, right from your phone. These people don't do any research on the company. They see news stories on the company all the time, and news stories that the stock went up XX% So when you have people casually buying stocks I feel like they get inflated past the point that makes any sense, and thus become incredibly overvalued. Seasoned investors would see this and stay far, far away from these businesses.
