Compared with its close competitors within the same industry, KOSPI, since the monthly volatility of Dongsuh was the lowest, the earnings rate over one month was also relatively lower than that of its peer group's. Over the recent month, the Return On Risk, the return on investment with consideration about risk, was -6.6%. Though the volatility was the lowest among its peer group, the Return On Risk was low as stock price decline.
