Investors may become optimistic while reading good results of a company in past and increase pessimism for a company for its bad results .
Investors may belief that a healthy growth in past may be representative of high growth rate in future and they may not realize that growth may randomize in future .

Investors would shed their initial conservatism at the time when stock price would reduce and move very little.
