Suck an investment decision is to some extent extremely difficult to make. In this paper, we employed the TOPSIS technique with which we considered only the financial factors due to the availability of obtaining relevant data. Powerpoint Templates Page 3 Introduction A difference between TOPSIS and existing method ◦ The existing method · Consider only the financial ratios influencing the stock price. ◦ The TOPSIS method · Do grouping all the financial ratio using a factor analysis. √ The financial ratios usually involve the subordinate relationship among them. → total rate of return = ratio of net income to net sales ⅹtotal asset turnover ratio We implemented a comparison analysis for the preference ordering determined by between the general four financial classifications and the TOPSIS.

The financial analysis is fundamental method which decides the best investment alternative, in the same way TOPSIS is one of the decision-making techniques selecting the best stock. So, we will analyze that the financial analysis compare with the result of TOPSIS. Powerpoint Templates Page 28 Compare the TOPSIS Result with the Financial Analysis Result We execute the Spearman’s rank correlate analysis in order to evaluate measurably the relationship between financial analysis result and TOPSIS result. The Spearman’s rank correlate analysis ◦ The Spearman’s rank correlation coefficient is used to analyze relationship between two continual variables, if they are the criterion of the rank. ◦ The Spearman’s rank correlate analysis coefficient can have the values from “-1” to “1”. · If the value is “1”, it means that they have same order of ranking, on the other hand, the value is “-1”, it shows that they have completely reversed order.

Powerpoint Templates Page 36 The concluding remarks We present one unique method when choosing the bestinvestment-alternative, so called TOPSIS to make a determination of the order of priority between stocks. Then, we compare the financial analysis result with TOPSIS result to figure out the relation between two. As a result of correlation analysis, we know the financial analysis is low correlation with TOPSIS. ◦ It means the ranking of financial analysis is not equal to the ranking of TOPSIS, although we use the same base factors to determine the preference order in the stock market. Powerpoint Templates Page 37 The concluding remarks We can explain the differences between two methods through two. ◦ First, we can be explained depending on whether we conduct the factor analysis. · TOPSIS: we execute the factor analysis to reduce the number of factors by grouping the factors which are same effect on stocks. ◦ Second, we can describe contingent upon whether to apply weight value in the stocks. · Financial analysis : the same weight in each factor. · TOPSIS : A different weight according to degree of effect on stock price. Powerpoint Templates Page 38 The concluding remarks We regrettably failed to set up the benchmarking base to compare the TOPSIS result. So, we need to find out the sound and acceptable benchmarking base which will be the following research. Powerpoint Templates Page 39
