A Now and then Rankings of the Companies in the Korean Building Construction Industry

Due to the peaceful mood among South Korea,North Korea, and the U.S.A., which had been developed in these days, again the building construction companies in Korea have received much attention from the domestic and oversee stock investors. This geopolitical situation made us curious about the companies and investigate their rankings to compare with the result of the previous study done in 2010. As a result of this study, it was found that 6 out of 18 companies which had been initially taken into consider for the study in 2010 disappeared from the Korea Composite Stock Price Index(KOSPI) marketduring the last 8 years, and the rankings of the two studies were so greatly mismatched. The rankings of the companies was determined by the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) method mainly. However, we conducted making the rankings based on the approach of financial ratio analysis and came to an conclusion that there existed much similarity between the two rankings in a statistical sense, which requires us to be careful to generalize.
