The purpose of this study is to compare the valuation of technology firms in the KOSPI and KOSDAQ. This study analyzed 224 market reports for KOSDAQ firms and 602 reports for KOSPI firms. We compare the two markets under 3 definitions on the accuracy of stock price forecasting. Findings are as follows: Although PER multiples is the most used method of valuation, KOSDAQ valuation more heavily relies on the method than KOSPI valuation. In stock market, the period of earnings forecasting is mostly 2-3 years. Multiples of KOSDAQ is generally higher than those of KOSPI. Even for technology firms, valuation in KOSPI mostly relies on earnings of the company, but that in KOSDAQ mostly relies on relative price. In stock price forecasting, generally overestimation prevails. Moreover, forecasting of KOSPI reports is more accurate than that of KOSDAQ reports. ROE and COE of KOSDAQ firms are generally higher than those of KOSPI firms.

This paper empirically examines the portfolio diversification effect using data from both KOSPI and KOSDAQ. In KOSPI market, portfolio diversification effect disappears when more than 18 stocks are added in the portfolio. About 63% of portfolio risk is eliminated. In KOSDAQ market, the maximum portfolio diversification effect is achieved when 17 stocks are at least included in a portfolio. The maximum cumulative risk reduction is 35%.

This study Investigates the short and long-run dynamic relationships between the domestic and U.S. stock markets for the period of declining stock prices. It Is well known that the domestic stock market variations are largely caused by the U.S. stock market movements. Multivariate causal tty test Is utilized to examine the lead-lag relationships among four stock prices of KOSPI and KOSDAQ In the domestic part and DOWJONES and NASDAQ In the U.S. part. When the stock prices tend to decrease In the long run, It Is found that both KOSPI and KOSDAQ have closer relations with NASDAQ than DOWJONES. When both of domestic stock markets are severely fluctuate, bidirectional causal relationships appear to exist between NASDAQ and each of KOSPI and KOSDAQ. On the other hand. when the domestic stock markets are relatively stable, unidirectional causality Is found to exist between NASDAQ and each of KOSPI and KOSDAQ. which is explicitly validated by the analysis of variance decomposition.

This study aims to test the valur relevance of development cost particularly focusing on IT firms of KOSDAQ. Test period is from 2005 to 2007 and the samples are 2,271 year-firms including 1,692 firms that reported development cost in financial statements. The basic test model is a modified Ohlson(1995)'s linear model. The empirical results show that there is the negative relation between stock price and development cost reported as asset. It means that development costs reported as asset is considered as expense in the market. It implies that development activities of KOSDAQ IT firms is not related to market-leading technologies or goods. Otherwise it might reflect the conservative valuation of market on the unstability of KOSDAQ market itself.

본 논문은 1999년과 2005년 두시점 간에 코스닥시장과 코스닥상장기업간의 진성성장 상관패턴을 분석하여 코스닥시장의 진성성장에 코스닥상장기업의 재무우량화가 기여한 정도를 평가하는 것에 초점을 두었다. 특히 본 연구는 진성성장 개념을 통해 코스닥시장과 코스닥상장기업의 단순한 외형성장만이 아닌 질적 성장까지를 포함하는 성장도를 평가하였으며 이에는 유동성, 공정성, 변동성, 건전성 등의 지표와 1999년 말과 2005년 말 기준 코스닥 시가총액 30위 기업으로 대상으로 한 외형재무(매출액, 이익 및 이익률) 등을 비교하였으며 질적 재무로 지속적 이익의 규모 변화를 측정하였다. 이러한 분석을 통해, 본 논문은 크게 세 가지의 연구결과를 도출하였다. 첫째, 상장기업수와 거래량 및 거래규모가 증가하는 가운데서도 코스닥시장이 질적으로 성장할 수 있었던 동인인 기업의 수만 양적으로 증가한 것이 아닌 재무적 성과가 질적으로 우수한 상장기업들이 늘어났기 때문이다. 둘째, 시장의 변동성이 낮아지며 시장이 안정성을 이루는 동인은 상장기업의 이익의 질이 우수하였기 때문이여 특히 지속적 이익의 증가는 기업의 미래성장성을 높이며 단기적 투자보다는 중장기적인 미래 가치투자를 가능하게 하였기 때문이다. 셋째, 코스닥시장이 시장과 재무지표 중심의 상장폐지제도를 운영하며 시장의 투명성을 제고하고 이를 통해 진성성장을 이룬 것은 상장기업들이 시장중심의 지표를 적용해도 충분히 소화해 낼 수 있는 진성 재무성과를 보였기 때문이다.

국내 벤처산업은 정부 주도의 벤처육성정책, 정보·통신 기술의 발달, KOSDAQ시장의 활황 등으로 인하여 급격한 성장을 하였다. 그러나 최근 국내 벤처산업은 정부의 인위적인 정책과 지원으로 인한 압축성장에 따른 많은 폐해에 직면하고 있으며 장기 침체상태로 빠져들 가능성이 있어 보인다. 이것은 국내 벤처산업이 선진국에서 볼 수 있는 벤처캐피탈시장에 바탕을 둔 자생적 성장을 하지 못했기 때문이다. 본 논문은 향후 국내 벤처산업의 지속적인 발전에 관건이 될 벤처캐피탈시장의 현황을 분석하고 개선방안을 모색하였다. 또한 본 논문은 국내 벤처캐피탈시장을 활성화시키기 위한 방안으로 투자조합의 규모 증대 및 해외 벤처캐피탈의 유입 등을 통한 자금조달인의 확대, 지분참여 투자형태로의 자금운용, 코스닥시장의 활성화 등을 제시하였다.

본 연구의 목적은 코스닥시장에서의 증권시장의 이상현상(anomaly effect) 중의 하나인 월바뀜(TOM)효과에 대해 검증하고 이를 코스피시장의 연구 결과와 비교하여 코스피시장의 연구결과의 지지정도와 새로운 특징을 규명하고자 하는 것이다. 이를 위해 본 연구에서는 1996년 1월부터 2013년 12월까지(18years, 216months) KOSDAQ의 일별 표본자료를 기초 자료로 하여 연도별, 월별, 이벤트별 TOM효과를 검증하였다. 또한 코스피시장과 코스닥시장의 월바뀜효과를 명확히 비교 검증하기 위해 월바뀜(TOM)기간을 다소 달리하여 양시장의 TOM수익률과 나머지기간(ROM)의 수익률을 비교 검증하였다. 연구 결과를 보면 연도별, 월별, 이벤트별, TOM기간을 달리한 분석에서 TOM효과는 ROM효과에 비해 일반적으로 항상 존재하는 것으로 분석되어 양(+)의 TOM효과를 입증하였다. 또한 변동성이 큰 코스닥시장의 TOM효과가 코스피시장보다 컸으나 다소 연도별로 효과가 안정적이지 못하였으며, 분산이 비교적 크게 나타난 금융위기 전후 시기에는 코스닥에서 TOM효과가 더욱 뚜렷하게 나타나는 것으로 분석되었다.

From the perspective of the domestic capital markets, there have been few researches on the financial characteristics of the firms belonging to the KOSDAQ(Korea Securities Dealers Automated Quotation) market, in comparison with those of the firms in the KOSPI. This study has performed three hypothesis tests to obtain the following results: By employing the 'panel data' analysis, it was found that, for the book-value based leverage, all of the six proposed IDVs were statistically significant as the financial determinants of leverage, across the two proxies measuring profitability (i.e., PFT and ROE), while all of the IDVs except VOLATILITY, also seemed to be the attributes to explain the market based dependent variable in the model with the PFT. Moreover, there may be statistically significant (structural) changes (or quasi-experiment) ) between the pre- and post-U.S. financial crisis in the year of 2008, when measured the leverage with the market-value basis with utilizing the Chow F-test. Finally, based upon the logistic regression results, the probability for a firm to be classified into the Prime section in the KOSDAQ market, may be higher, as its profit margin and asset turnover increase.

Since 1996 when Kosdaq market was set up, serious doubt has been raised regarding the efficiency of the market. The most important question is whether this market can reflect the real value of the venture company quoted on it. In order to answer this question, this study aimed to evaluate venture companies in Kosdaq market adopting the concept of real option theory. From the results of empirical analysis, we found that in the early 2000, there was serious over-valuation problem. On the contrary, in the recent period of economic recession, under-valuation problem is quite prevalent. We also present our methodology and empirical results confirm the conjecture that option premium outweighs the DCF valor for the newly born and high-technology intensive venture companies. We hope that the empirical results shed some light on the policy prescription to improve the efficiency of Kosdaq market.

The purpose of this paper is an attempt to analyze the dynamic relationship between KSE and KOSDAQ, two competing markets in Korean stock market, in the viewpoint of competition. Lotka-Volterra model, one of well-known competitive diffusion model, is adopted to represent the competitive situations of Korean stock market and it is estimated using daily empirical index data of KSE and KOSDAQ during 1997~2001. The results show that there existed a predator-prey relationship between two markets in which KSE acted as a predator right after the emergence of KOSDAQ. This interaction was altered to a symbiotic relationship and finally to the pure competition relationship. We also perform an equilibrium analysis of the estimated Lotka-Volterra equations and, as a result, it is found that there is a market index equilibrium point that would be stable in the latest relationship.
