In unfrictionless markets, one measure of asset pricing is its height of friction. This study develops a three-factor model by loosening the assumptions about stocks without friction, without risk, and perfectly liquid. Friction is used as an indicator of transaction costs to be included in the model as a variable that will reduce individual profits. This approach is used to estimate return, beta and other variable for firms listed on the Indonesian Stock Exchange (IDX). To test the efficacy of friction-adjusted three-factor model, we use intraday data from July 2016 to October 2018. The sample includes all listed firms; intraday data chosen purposively from regular market are sorted by capitalization, which represents each tick size from the biggest to smallest. We run 3,065,835 intraday data of asking price, bid price, and trading price to get proportional quoted half-spread and proportional effective half-spread. We find evidence of adjusted friction on the three-factor model. High/low trading friction will cause a significant/insignificant return difference before and after adjustment. The difference in average beta that reflects market risk is able to explain the existence of trading friction, while the difference between SMB and HML in all observation periods cannot explain returns and the existence of trading friction.

Despite the fact that the implementation of 5% rule is widely recognized to enhance the transparency of capital market and fairness of corporate governance market, a few evidences present information effect of 5% rule. Using 7,088 non-financial firm-year observations listed on the Korea Stock Exchange from 2006 to 2012, we analyze the relation between trading volume and 5% rule disclosure. The results show that the daily and abnormal trading volume is increased when 5% rule disclosure is released. Moreover, the trading volume is significantly increased during cooling period. Specifically, trading volume is significantly greater when one day before cooling period or the expiration day of cooling period. We also find the information effect of firms with stable ownership structure before 5% rule disclosure is relatively smaller than the firms with unstable ownership structure with unstable ownership structure. These results imply that capital market participants use the information from 5% rule disclosure and reflect in their real economic decision.

Purpose - Prior theories predict a negative correlation between stock liquidity and dividend payout propensity. We test this hypothesis by examining the sample Korean retail firms. Research design, data, and methodology - We construct four different types of stock liquidity measures and investigate how these stock liquidity variables affect dividend payout propensity by employing the logit regression model. The retail firms listed in the KOSPI and KOSDAQ markets are analyzed from 1990 to 2015. Results - Our estimation results support the liquidity hypothesis if we adopt the stock turnover rate as the stock liquidity measure, particularly for the retail firms listed in the KOSPI markets and for non-conglomerate firms. Yet, our estimation results adopting the illiquidity measure of Amihud (2002), the proportion of non-trading day, and the volume of trading do not support the liquidity hypothesis. Conclusions - Our findings provide mixed results for the validity of stock liquidity hypothesis, which enriches the existing literature. In terms of turnover rate, the stock liquidity hypothesis holds robustly. Yet, we are not able to find any empirical evidence supporting the hypothesis if we use the other three measures of stock liquidity.

This paper is to give some hints to solve the problems of the Korean The third Market suffering from the extreme shortage of the liquidity. To solve that problem, this paper mainly compare the liquidity indices of the Third Market with that of the Japanese third market, that is Mothers. The main liqudity indices of the Mothers shows better than that of the Korean Third Market redardless of the small numbers of the listed Firms. The main differences in the liquidity levels between two markets is to caused by the trading system. The Korean Third Market has been adapting the one-to-one trading system which most stock markets of the world gave up that system owing to the inefficiency. This paper shows the proper trading system for the Third Market is competitve trading system partialy combined with the market maker system beacause of the small firm characterristics.

By explaining the essence of corporate governance as well as disclosure and transparency, the study examined the guarantees of applying disclosure and transparency to firms listed on the Saudi stock exchange. The research also addressed the disclosure and transparency duties of firms listed on the Saudi stock exchange. Finance to prepare a prospectus, as the Capital Market Authority's regulations required that the prospectus includes information that enables the investor in securities to make his investment decision based on real foundations based on the issuing company's financial position and to ensure that companies fulfill that disclosure in the prospectus. Firms who fail to disclose are required by law to do so, and the Capital Market Authority's laws mandate companies listed on the financial market to regularly report fundamental events linked to the issuer or the securities issued by it. The Capital Market Authority must make it available to the public dealing with the business issuing the securities, and The Capital Market Authority's Law and Regulations have imposed fines on corporations that do not comply with disclosure and make the Board of Director's report available.

The involuntary delisting of public companies has a detrimental effect on economies caused by the loss of stock value and confidence in the capital market. Previous studies have focused on prediction or prevention models for firm delisting events using various financial and accounting information. However, the timely disclosure of companies, another important indicator, has not been investigated before in connection with companies that have been delisted. To address this gap, this study investigates the timely disclosure behavior of companies prior to delisting using sample firms listed on the Korean stock market between 2000 and 2014. The results show a significant correlation between the frequency of timely disclosure and delisted firms prior to their delisting on the Korean stock market. The delisted companies appear to increase their timely disclosure to deliver specific information to the public. Furthermore, these companies are likely to increase the frequency of timely disclosure as they get closer to their delisting. Notably, the timely disclosure of delisted firms has a capital market effect; namely, timely disclosure increases trading volume while decreasing the market value of the shares, reflecting price efficiency. This study appears to be the first that considers timely disclosure in the involuntary delisting literature.

본 연구는 외국인지분율이 투자자들 간의 상이한 믿음에 어떠한 영향을 주는지에 관한 실증분석을 실시하였다. 한국은 외국인 직접투자도 활발하지만 외국인 간접투자 또한 활발하다. 따라서 외국인지분율과 관련된 투자 의사결정에 관한 논의는 한국경제를 위해 간과할 수 없는 분야라 할 수 있다. 이에 본 연구는 2001-2011년 기간 동안 유가증권시장 상장법인(금융업 제외)을 대상으로 실증분석을 실시하였다. 그 결과 외국인지분율의 회귀계수는 유의한 음(-)의 값을 가지는 것으로 나타났으며, 최소자승법(ordinary least squares)과 토빗(tobit)분석을 사용하여도 일관된 것으로 나타났다. 또한, 본 연구에서는 외국인투자자의 투자성향(장기 투자성향과 단기 투자성향)을 고려한 후, 각각의 집단에서 외국인지분율이 투자자들 간의 상이한 믿음에 미치는 영향을 추가 분석을 실시했다. 본 연구는 외국인지분율이 일반 투자자의 투자의사결정에 어떠한 영향을 미치는 지를 분석함으로서 외국인 간접투자에 대한 분석을 했다는 점에서 의의를 갖으며, 일반 투자자들이 투자의사결정시 외국인투자자를 고려하고 있다는 실증결과를 제시한다는 점에서 함의점이 있다.

본 연구는 중소 및 초기벤처기업이 간접금융과 정책금융에 의존하는 대신 자본시장을 통해 직접 자금을 조달하게 하는 코넥스시장의 재도약 방안을 제시한다. 코넥스시장에서 인적, 물적 상장인프라가 제한된 기업들은 성장하고 벤처투자자와 같은 모험자본은 투자의 조기 회수를 기대할 수 있다. 그러나 2013년 개설 당시부터 제기되어 온 유동성 부족과 거래량 부진은 수급의 문제에 그치는 것이 아니라 가격발견기능까지도 저해해왔다. 또한 코스닥시장의 적극적인 상장요건 완화와 장외시장인 K-OTC시장의 투자수요 흡수로 신규 상장기업이 급감하며 제도 개선이 더욱 요구되고 있다. 본 연구는 비상장기업이 코넥스시장에 상장하고, 이후 코스닥시장에 이전하기까지 작용하는 규제 또는 제도의 개선을 다섯 가지로 제시하였다. 먼저, 투기적 수요에 대한 우려가 적으므로 개인투자자에 대한 기본예탁금 규제를 폐지하여 투자자를 확대해야 한다. 둘째, 지정자문인이 신규 상장사를 발굴하고 지원하는 역할에 충실하도록 지정자문인이 공시를 대리하지 않고 기업이 직접공시하도록 전환하여야 한다. 셋째, 거래량을 증가시키기 위해 상장유지요건으로 도입된 지분분산 5% 의무화를 25%로 확대하되 인센티브 부여 방식으로 운영해야 할 것이다. 넷째, 코스닥시장이 상장요건으로 이익실현요건을 완화해가고 있으므로 신속이전상장에 과도하게 부과된 이익실현요건을 현실화해야 한다. 마지막으로는 성실공시와 지분분산을 충족하고 투자자보호 장치를 마련한 코넥스기업들이 코스닥으로 자동이전상장한다면 시장참여자의 불확실성을 감소시키고 코넥스시장의 인큐베이팅 역할을 강화할 수 있을 것이다.

This paper studies the behaviour of stock prices on the ex-dividend day in the Korean stock market. Since a majority of listed Korean firms are December firms whose fiscal year end in December and whose ex-dividend day falls on the same calendar day in the year, we use stock prices of Non-December firms to estimate the general stock price movements not related to cash dividends. We estimate excess returns on days around the ex-dividend day. Our major findings are (a) there is no tax clientele effect in Korea, (b) the opening price stock prices fell by the amount of the current cash dividend per share until 2001, but it does not fall as much as the current dividend per share since 2001. Furthermore, in contrast to the U.S. and the Japanese findings, (c) stocks earned negative excess returns on the ex-dividend day until 2001, after which all stocks are earning positive excess returns on the ex-dividend day, and (d) the closing stock price on the ex-dividend day that used to be even higher than the cum-dividend price until 2001 is lower than the opening stock price since 2001. The evidence suggests a structural break has happened around the year 2001.

Modern investment theory has empirically proved that stock returns can be explained by several factors such as market risk, firm size, and book-to-market ratio. Other unknown factors affecting stock returns are also believed to still exist yet to be found. We believe that one of such factors is the operational efficiency of firms in transforming inputs to outputs, considering the fact that operations is a fundamental and primary function of any type of businesses. To support this belief, this study intends to empirically study the relationship between firm efficiency and stock price performance. Firm efficiency is measured using data envelopment analysis (DEA) with inputs and outputs obtained from financial statements. We employ cross-efficiency evaluation to enhance the discrimination power of DEA with a secondary objective function of aggressive formulation. Using the CAPM-based performance regression model, we test the performance of equally weighted portfolios of different sizes selected based upon DEA cross-efficiency scores along with a buy & hold trading strategy. For the empirical test, we collect financial data of domestic firms listed in KOSPI over the period of 2000~2016 from well-known financial databases. As a result, we find that the porfolios with highly efficient firms included outperform the benchmark market portfolio after controlling for the market risk, which indicates that firm efficiency plays a important role in explaining stock returns.
