Accounting and Finance Research, 2019, vol. 8, issue 2, 226

Abstract: This study examines the determinants of stock returns of IT companies based on index model. The study examines the index model using the case analysis of stock returns of three IT Companies-Apple, Google and Microsoft. The analysis was done using the latest five-year monthly data. The study reveals that market index returns is a powerful determinant of stock returns. In terms of sensitivity as measured by beta values, Apple was most sensitive to fluctuations in market returns followed by Google and Microsoft stock returns. The study also examines the predictive ability of current beta using five-year data series of 15 IT companies. The results were statistically insignificant.Â
