Valuation of business enterprises can be understood as the activity of working capital that determines the market value. A business valuation can be used to determine the value of an existing business or shareholders’ equity. The main purpose of the evaluation is to determine the current market value of the enterprise and shares, and at the same time the selling price, and finally to insure the activity of the enterprise. In recent times, many economic reforms, as well as political initiatives to develop entrepreneurship, have made evaluation an important activity for the private sector.We can call valuation activity the heart of finance. When thinking about increasing the value of a firm, we can first consider our investment, financing and dividend decisions in corporate finance. We spend available resources during portfolio management to find businesses that are trading below their true value, ultimately hoping to profit as prices move closer to value. When we examine efficient markets, we analyze how quickly market prices can bounce back from real value. First, we need to understand what we should consider when determining the value of a firm and how we can estimate this value.
