Тема: CAPITAL STRUCTURE AND FIRM VALUE: EVIDENCE FROM THE RUSSIAN STOCK MARKET

The cost of capital is a critical factor in company valuation as it determines the rate at which future cash flows are discounted. Financial managers play a crucial role in optimizing capital structure to maximize firm value. Among theories that address this issue, one prominent theory is the trade-off theory (Modigliani and Miller, 1958). According to this study, companies must balance the benefits arising from increased debt ratios, such as tax advantages, and the costs associated with a higher risk of bankruptcy. Although alternative theories have emerged to explain specific frictions and imperfections of capital markets, trade-off theory remains central to debate in the finance literature because it considers benefits and costs.
While extensive theoretical research exists on the capital structure, a clear methodology for calculating optimal capital structure remains underdeveloped, and empirical evidence on the actual benefits of optimization is sparse. This research aims to fill the gaps by exploring both the theoretical and practical aspects of capital structure in the Russian stock market. Given the critical role of optimal capital structure in maximizing shareholder wealth, it seeks to determine how Russian companies can achieve an ideal balance of debt and equity and whether it provides any benefits.
Most of existing literature in the context of capital structure is devoted to mature markets such as USA, although emerging markets, including Russia, are attracting investors due to their accelerating economic growth. Despite this, the determination of capital structure that maximizes firm value for Russian stock companies remains relatively scarce. Given that capital structure plays a crucial role in maximizing shareholder wealth, it is imperative to study how to determine the optimal level of debt and equity.
The research is structured to investigate the capital structure of Russian companies from two distinct perspectives. Initially, the study examines capital structure trends over time across sectors, analyzing whether firms with lower debt relative to their sector averages are valued higher or lower compared to their more levered peers. This part seeks to derive insights on market perceptions and valuation implications based on these trends. The second perspective involves proposing a model to assess the alignment of companies with the trade-off theory's principles, comparing their realized capital structures with the optimal ratios. It evaluates whether companies that align closely with these optimal structures generate higher returns, thus determining the practical benefits of adhering to the proposed interpretation of an optimal capital structure.
This comprehensive approach contributes to understanding the optimal capital structure for Russian companies and highlights the potential advantages of adopting an optimized approach. The findings will be beneficial for financial managers, shareholders, and industry professionals, aiding in more informed decision-making regarding capital structure adjustments and wealth maximization.
The goal of this research is to estimate the benefits of optimizing capital structure in Russian public companies. The study aims to provide valuable insights into the potential advantages of capital structure optimization and contribute to the understanding of capital structures in the Russian market.
Research Questions:
1. How do different sectors in the Russian market vary in terms of their optimal capital structure?
2. What is the extent of alignment between Russian public companies' realized capital structures and the optimal ratios suggested by the trade-off theory?
3. What are the benefits that can be achieved through capital structure optimization in terms of maximizing shareholder wealth and market capitalization?
Managerial Implications:
The findings of this research will have practical implications for financial managers, shareholders, and industry professionals in the Russian market. By providing insights into the benefits of capital structure decisions, the study can guide financial managers in making informed decisions regarding the debt-to-equity level of their companies. The research can also help shareholders understand the potential advantages of adopting companies with an optimized capital structure for companies, enabling them to assess the long-term value-creation potential of their investments. Additionally, industry professionals, such as valuation departments of prominent companies, can utilize the research findings to provide recommendations to Russian clients on how to optimize their capital structure and enhance market value.

A comprehensive analysis carried out in this study reveals essential insights into the capital structure dynamics of Russian companies and their impact on financial performance. Significant variability across sectors emerged, reflecting individual industry characteristics and economic conditions. Despite these differences, a general trend was identified: firms categorized underleveraged consistently outperformed their overleveraged counterparts. This finding underscores the benefits of maintaining conservative debt levels, which are more favorably accepted by investors and lead to higher returns.
Comparing the optimal debt ratios with the realized weighted average debt ratios across sectors confirms that different sectors indeed have distinct capital structures. The findings of this study are consistent aligned with the hypothesis that optimal capital structures vary across sectors, reflecting their unique business characteristics and risk profiles. For instance, sectors such as Communication Services and Real Estate have shown significant leverage trends, while sectors like Consumer Discretionary and Materials showed more cautious or fluctuating approaches to debt. Optimal ratios take into account industry-specific risks and financial behavior, suggesting that a one-size-fits-all approach to capital structure is suboptimal.
Another notable finding is the average nature of firms with low levels of financial leverage, supporting the hypothesis that firms tend to adopt conservative debt management practices. This approach may be driven by a desire to maintain financial flexibility and avoid the risks associated with high leverage. Such practices suggest that firms are not fully utilizing their debt capacity to enhance market value, leaving room for potential increases in leverage to optimal levels.
Analysis of the Optimal Capital Structure Neighborhood (OCSN) measure further illustrates the superior performance of low-leverage companies: companies that maintained less than optimal debt ratios recorded geometric returns of 10.6%, significantly outperforming both the market portfolio and companies with excessive debt ratios, which recorded negative profits. Valuable insights for financial managers and investors are emerging, highlighting the benefits of maintaining lower leverage to improve company value and financial performance. The consistency of these results with the Sector Capital Structure Neighborhood (SCSN) analysis highlights a broader market preference for lower leverage, due to reduced financial distress risk and greater financial flexibility.
Improvement Measures (IM) provide further insight into dynamic capital structure adjustments. Firms that improved alignment with their optimal capital structure achieved geometric returns of 10.1%, compared with just 3.2% return for firms that deviated from their optimal structures. This measure emphasizes the importance of strategic management of capital structure. Companies that proactively adjust debt ratios near optimal levels tend to achieve better financial performance. Initial poor performance of the measure can be attributed to the lower usage of debt at the beginning of the investigation period. However, as companies increase their debt levels and grow toward optimal structures over time, their performance improves significantly. This trend shows that companies still have room to further optimize their capital structure and achieve higher profits.
The proposed variant of optimal capital structure calculation not only provide theoretical insights but also bring practical value to shareholders and managers: adjusting the capital structure to an optimal level will improve stock market value, reduce the cost of debt and help to achieve greater financial stability. These results are consistent with the dynamic view of capital structure proposed by Karpavicius (2014) and Im et al propose (2020), emphasize the need to continuously monitor and adjust the capital structure in response to changes in market conditions and strategic decisions.
In summary, capital structure management is essential in enhancing firm value. The findings highlight the benefits of maintaining conservative debt levels and the potential for firms to increase their debt to optimal levels. Future research should explore non-linear relationships between the cost of debt and its determinants, and further study the underdebted phenomenon to understand investor reactions to debt redemptions. By integrating these insights, financial managers can better navigate the complexity of capital structure decisions, optimize debt levels and improve their competitive position in the market.
