In addition, these techniques cannot help investors compare business on ambiguity multi-criteria and desire accumulation of data about the market. Therefore, portfolio selection with two significant financial ratios using the ELECTRE III method is proposed for small investors to make trading decisions. In order to demonstrate the effectiveness of this research, it is compared to the situation where a fix-percentage allocation existed and data was collected from the stock exchange of Thailand (SET). Empirical results show that portfolio selection with the ELECTRE III method offer significantly better ranking performance than the fix-percentage allocation method.
