• Herd instinct is a behavior in which people form groups and follow the actions of others.

  • In finance, herding occurs when investors follow the crowd rather than their own analysis.
  • It has a history of starting large, unwarranted market rallies and selloffs that are often based on a lack of fundamental support to justify them.
  • The dot-com bubble of the late 1990s and early 2000s is a prime example of the herd instinct at work.
  • People can avoid herding by doing their own research, making their own decisions and taking risks.
