Growth and survival of a business depend on crucial corporate decisions. Wealth maximisation, profit maximisation, market price of shares etc. are being considered as the outcomes of crucial corporate decisions. Financial and economic factors are influencing corporate decisions and stock market movements are very sensitive due to the nature of such external factors and corporate decisions. Major corporate decisions like ‘financial’, ‘new ventures/initiatives/developments’ and ‘acquisition/amalgamation/merger’ are to be examined very closely for finding the interesting response of stock markets which would contribute values to all stakeholders. This paper makes a critical analysis on WIPRO corporate decisions and it corresponding implications on share prices.
