I have been watching the pattern of rise of sensex for the last few years. Whenever foreign investors are involved, they start buying the shares pushing up the price. One fine day they sell off the shares making huge profits. This triggers bear run and the sensex comes down heavily. Once again they start the process and it has continued ever since. This is not to underestimate the real worth of a company. On the whole most of the scrips are overvalued and Indian market shares need drastic correction.
