The Modigliani-Miller (MM) hypothesis is a theory in financial management that suggests a positive relationship between capital structure and corporate performance. It posits that companies with higher levels of capital intensity (meaning a higher proportion of debt relative to equity), are likely to outperform those with lower levels of capital intensity.
The theory is based on the idea that debt financing is more risky than equity financing. When a company issues debt, it is obligated to repay the principal amount plus interest to the bondholders. If the company defaults on its debt obligations, the bondholders may lose their investment. This risk is perceived to be higher for companies with higher levels of debt, thus leading to lower capital intensity.
The MM hypothesis has been supported by a number of empirical studies. For example, a study by Myers and Majewski (1988) found that companies with higher levels of capital intensity are more likely to be profitable. Another study by Jensen and Warner (1994) found that companies with higher levels of capital intensity are more likely to invest in projects with higher returns.
The MM hypothesis has both strengths and weaknesses. On the one hand, it is a well-supported theory that has consistently been able to generate positive alpha (the difference between the return on a company's stock and the risk-free rate). On the other hand, the theory has also been criticized for being too simplistic and not taking into account other factors that may affect a company's performance.
Despite these criticisms, the MM hypothesis remains a valuable tool for understanding the relationship between capital structure and corporate performance. It is a useful framework for analyzing the potential impact of capital structure changes on a company's overall financial health and profitability
