What you need to know about rational herding.

It is important for investors to be aware of the concept of rational herding in financial markets. It often occurs when one investor observes another acting in a certain way, for example, selling a particular instrument unexpectedly. The first investor may then believe that the second knows something that they don't, such as some sort of negative information about the firm in question. If this effect is multiplied many times over, it can cause a huge rush of people selling the asset in question, and the share price falling. This in turn can lead to wider market instability.
