There are three ways of security analysis-fundamental, technical, and efficient market hypothesis. I introduce these three ways briefly, and explain technical analysis in detail, moreover directional movement index technic and sequential technic. These two technics are rarely used in Korean stock market because they are not familiar with Korean Stock Market. I compare returns which are taken by using these two technics for past 5 years data and using past KOSPI. With the results, I suggest whether or not to use these technics in Korean Stock Market. In summary these two technics are not supposed to be used in Korean Stock Market without considering other methods which can be helpful to judge the market condition.
