Market is filled with unique players and everyone has their own strategies, not everyone will follow the footstep of Warren Buffett. Some people only care about the technical movement of the price, plus there are greed and fear as one of the emotional factors within the market. These underlying factors will make a stock either flew to the moon or drop down like a melted ice. As Warren Buffett said, "Be fearful when everyone is greedy and be greedy when everyone is fearful."
