Objective: This study deploys an earnest effort to understand the factors that affect the managers involved in managing the portfolio of funding in companies. Capital structure decision is one of the crucial decisions that finance managers have to make. This study tries to identify a host of factors controlling the attitude of finance managers in choosing different sources of financing, as reflected in financials of respected companies. Design/methodology/approach: Based on the data available in different secondary sources (such as the financial statements published by the sampled companies), an exploratory form of research is applied here. The samples for the study are selected from companies which are listed in Dhaka Stock Exchange (DSE) under pharmaceutical, textile, and banking sectors. Different descriptive and inferential statistical tools are used to present the data and test relevant hypotheses by using statistical package for the social sciences. Findings: Based on the literature review, the study has identified a couple of factors affecting capital structure decision. These factors are replicated in selected Bangladeshi firms to understand their implications. Although the study fails to report any determinants having strong relationship which is statistically significant, the model passes goodness-of-fit test and residual analysis, which shows the presence of normality.Research limitations/implications: The findings of the study could not be generalized due to some inherent limitations of the research. The study only covers selective companies from three sectors, leaving others from the preview of analysis, which limits the scope of the study. However, the findings of the research could be helpful for individual firms to find their status in the recent trend of practicing capital structure decision; thereby they can adopt or revise their policy in this regard. Another major limitation of the study is that, it applies a quantitative form of analysis based on the data published in general purpose financial statements. It would be more beneficial if quantitative findings could be validated through qualitative analysis in order to bring data triangulation which is left for further study. Extending the analysis to cover all the firms listed in DSE can give a better outlook on capital structure issues in Bangladesh.
