Measurement of risk plays an important role for any investment decisions because risk can be eliminated to some extent but not completely. The degree of risk varies from one sector to other sector based on company's internal and external influences. The risk has been categorised as unsystematic risk (company risk) or systematic risk (market risk). Most of the investors are taking beta as the measurement to know the market risk for the any of the investment securities. The purpose of this paper is to find out the stability of beta for different sectors of Indian economy over last 10 years. The period of analysis covered for this study is September 2007 to October 2017. For CPSE indices data available only from July 2008 and Infrastructure indices from May 2014 and for India manufacturing indices from June 2015.
