Herd behavior.
Herd behavior describes how individuals in a group can act together without planned direction. The term pertains to the behavior of animals in herds, flocks and schools, and to human conduct during activities such as stock market bubbles and crashes, street demonstrations, sporting events, religious gatherings, episodes of mob violence and even everyday decision making, judgment and opinion forming.
-----------------
Some followers of the technical analysis school of investing see the herding behavior of investors as an example of extreme market sentiment.[5] The academic study of behavioral finance has identified herding in the collective irrationality of investors, particularly the work of Robert Shiller,[6] and Nobel laureates Vernon Smith, Amos Tversky, and Daniel Kahneman.
Hey and Morone (2004) analysed a model of herd behavior in a market context.
