Cost of capital: The effect to the firm value and profitability of companies: Evidence of a selected group of companies on the Sarajevo and Banja Luka stock exchanges

The weighted average cost of capital is the rate that companies must pay to shareholders and creditors. Therefore, it is a risk-adjusted discount rate for the company's cash flows. The paper will calculate the weighted average cost of capital for a selected group of companies listed on the Sarajevo and Banja Luka Stock Exchanges, as well as profitability indicators such as: ROA, ROE and net profit margin. Therefore, the main goal of this paper is to investigate whether there is interdependence in the movement of the weighted average cost of capital and profitability indicators of the selected group of companies in the stock market indices SASX-30 and BIRS. The research results show that the WACC ranges from a minimum of 5.11% to a maximum of 10.87%. Likewise, the research results show that there is a negative connection and correlation between WACC on the one hand and a selected group of profitability indicators on the other hand.
