Triggers each time were different. The market provided its own triggers for a rise or fall. No operator or institution can be single-handedly responsible for rise or fall of the entire market for a prolonged period. Ketan Parekh also rode the worldwide boom in technology but could not survive the fall. He was probably just a passenger and not the driver of the boom.
Markets are much bigger than any individual.
Fall of an individual cannot mean the end of the markets. A look at past trends shows that markets always come back, and each time with even greater vigour. However, it may take a few weeks or even months for genuine investors to gain enough confidence to make a call on the markets. We expect the institutions, foreign and domestic, to lead the comeback when economic conditions improve. So those who are despairing at the fall of the bull operator should not forget that public memory in this market is rather short.
