Abstract:
Investment valuation formulas are well-known and popularly used in Europe and USA. There are many types of investment valuation formulas such as Economic value added (EVA), Shareholder value added (SVA), Cash Flow Return on Investment (CFROI), Total Business Return (TBR) and Cash Value Added (CVA). The objective of this research is to study the appropriateness of the various Investment valuation formulas for stocks of public companies traded in the Stock Exchange of Thailand. The companies selected for the thesis research are in the Agro and Food Industry sector (4 companies), Consumer Products (3 companies), Financial (4 companies), Industrial (3 companies), Property and Construction (3 companies), Resources (3 companies), Services (3 companies), and Technology (3 companies). The result shows that EVA, in comparison to other valuation formulas, is appropriate for Consumer Products, Financial, Industrial, Property and Construction, and Resources sectors. The sector with the highest coefficient of correlation is Resources with the value of 0.8. This means that EVA appears to reflect the stock values well, especially for the companies in the Resources sector. Moreover, an analysis of the relationship between investment valuation formulas and the economic indicators reveals that EVA has a direct relationship with GDP and the Manufacturing production index with one period time lag. The coefficient of correlation between EVA and the economic indicators ranges from 0.4-0.9. This result appears to confirm that EVA may be used in estimating the stock values without resorting to the national economic indicators.
