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.

The ultimate goal of this paper falls on assessing the magnitude of co- evolutionary pattern existing between the genuine growth of KOSDAQ and KOSDAQ-Listed Companies. This paper define the concept of "genuine growth" as including quantitative and qualitative growth of each entities. This paper take genuine growth indexes of KOSDAQ as liquidity, fairness, volatility, transparency, while that of KOSDAQ-Listed Companies as quantitative financial indexes and qualitative financial indexes. This paper brings three research implications as conclusions. First, growth engine of KOSDAQ resulting in its' qualitative growth besides quantitative one is founded on number of KOSDAQ-Listed companies showing outstanding financial performance qualitatively, Second, increasing permanent profit portion of KOSDAQ-Listed Companies have induced a long-term assessed investment rather than short insight speculation in the year of 2005. In addition, source of lowering market volatility and stabilizing market is strongly correlated with the excellency of profit quality among KOSDAQ-Listed Companies. Third, a high adaptability of KOSDAQ-Listed companies meeting with market sustaining requirements enable KOSDAQ to enhance market efficiency.

The Korean venture industry showed a rapid growth due to various government incentive measures, development in information technology, and explosive growth of the KOSDAQ market. Recently, however, the Korean venture industry has revealed numerous side effects, which seemed to be coming from excessively aggressive government involvement in the industry, and fallen into a deep depression. This phenomenon may imply that the Korean venture industry has been established by the government policy rather than based on the venture capital market, whereas the venture industry in advanced nations has grown up autogenously based on it. This paper analyzes the Korean venture capital market and suggests policy recommendations to revitalize the domestic venture capital market. They include facilitating the supply of funds through limited partnerships and overseas venture capital, extending the direct equity investment, and actively promoting the KOSDAQ market.

The purpose of this study is to verify TOM(turn-of-the-month) effect in the Kosdaq market, and that to compare to TOM effect of KOSPI for supporting degree of identification and to find new features. For this study, as the study basis sample, we used the daily data of the KOSDAQ from January 1996 to December 2013 and verified the TOM effect through yearly, monthly, classification by event as financial crisis, different period of TOM in order to clarify the effect of the KOSPI and KOSDAQ. As a result, We find that the TOM effect in KOSDAQ is always present uniformly in yearly, monthly, event-specific, which unlike TOM period also in KOSPI and generally TOM effect in KOSDAQ market which has larger volatility was appeared more pronouncedly than KOSPI market, and particularly TOM effect of KOSDAQ was larger than that of KOSPI on financial crisis occasion. But TOM effect of KOSDAQ was less stable than KOSPI.

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.
