This study investigates whether capital structure is value relevant for the equity investor. In this sense, the paper links empirical corporate finance issues with investment analysis. This study also integrates the Miller-Modigliani (MM) framework (1958) into an investment approach by estimating abnormal returns on leverage portfolios in the time-series for different risk classes. For most risk classes, abnormal returns decline in firm leverage. Descriptive statistics, simple and multiple regressions are used to test the hold indicator significance. The results reflect that the designed measures are the negative relationship between returns and leverage could also be due to the market’s pricing of the firm’s ability to raise funds if need be. Further avenues for research in this area include examining the stock return performance of companies based on the changes in leverage of the firms relative to their risk classes. It would be particularly noteworthy to examine the rate at which the information content of said changes is incorporated in the share prices of companies as well as in their long run returns This study encompasses all non-financial firms across the five sectors that cover all the various classes of risk. This study investigates neither the determinants of multiple capital structure choices nor changes in capital structures over time. Our main goal is to explore the effect of capital structure on cumulative abnormal returns. This study also examine a firm’s cumulative average abnormal returns by measuring leverage at the firm level and at the average level for the firm’s industry. And also examine other factors, such as size, price earnings, market-to-book and betas.
