This research attempts to formulate a new mean-risk model to replace the Markowitz mean-variance model by altering the risk measurement using ARCH variance instead of the original variance. In building the portfolio, samples used are closing prices of Indonesia Composite Stock Index and Indonesia Composite Bonds Index from 2013 to 2018. This study is a qualitative study using secondary data from the Indonesia Stock Exchange and Indonesia Bonds Pricing Agency. This research found that Markowitz's model is still superior when utilized in daily data, while the mean-ARCH model is appropriate with wider gap data like monthly observation. The Historical return has also proven to be more appropriate as a benchmark in selecting an optimal portfolio rather than a risk-free rate in an inefficient market. Therefore Mean-ARCH is more appropriate when utilized under data that have a wider gap between the period. The research findings show that the portfolio combination produced is inefficient due to the market inefficiency indicated by the meager return of the stock, while bears notable standard deviation. Therefore, the researcher of this study proposed to replace the risk-free rate as a benchmark with the historical return. The Historical return proved to be more realistic than the risk-free rate in inefficient market conditions.

Purpose - The purpose of this study is to clarify the mediating effect of profitability and activity in the relationship between productivity and stock return, assuming that the productivity of the company will affect share prices with the parameters of profitability and activity. Design/methodology/approach - The study extracted productivity indicators, profitability indicators, activity indicators, and share price-related indicators from 1999 to 2018 of non-financial enterprises listed on the securities market, and then classified them into three factors: productivity (labor productivity LP, capital productivity CP), activity (TT), and profitability (net profit rate NI, operating profit ratio OI) through the factor analysis method, and analyzed the impact of each factor on the stock return through steps 1 to 3. Findings - The regression analysis shows that productivity has a significant positive effect on the stock return through the full mediating effect of profitability and activity. Research implications or Originality - In a situation where the relationship between productivity and profitability is not clear, this study is meaningful in that it has empirically analyzed that productivity has a positive effect on the stock return by mediating effects of profitability and activity.

Purpose: The purpose of this paper is to confirm whether stocks belonging to the distribution industry in Korea have reversals, following large daily stock price changes accompanied by large trading volumes. Research design, data, and methodology: We examined whether there were reversals after the event date when large-scale stock price changes appeared for the entire sample of distribution-related companies listed on the Korea Composite Stock Price Index from January 2004 to July 2022. In addition, we reviewed whether the reversals differed depending on abnormal trading volume on the event date. Using multiple regression analysis, we tested whether high trading volume had a significant effect on the cumulative rate of return after the event date. Results: Reversals were confirmed after the stock price shock in the Korean distribution industry and the return after the event date varied depending on the size of the trading volume on the event day. In addition, even after considering both company-specific and event-specific factors, the trading volume on the event day was found to have significant explanatory power on the cumulative rate of return after the event date. Conclusions: Reversals identified in this paper can be used as a useful tool for establishing a trading strategy.

본 연구에서는 배당소득세율의 변화, 대주주지분율 및 기업의 배당정책이 주식수익률에 미치는 영향 및 이들의 상호작용에 대하여 분석하였다. 분석결과, 누적초과수익률을 종속변수로 하는 회귀분석에서 대ㅜ주지분율, 대주주지분율과 배당률의 상호작용항, 배당소득세율의 하락과 배당률의 상호작용항 및 배당소득세율의 상승과 대주주지분율과의 상호작용항은 양(+)의 부호를 나타내었다. 또한, 배당소득세율의 상승과 배당률과의 상호작용항 및 배당소득세율의 하락과 대주주지분율의 상호작용항은 음(-)의 부호를 보였다. 한편, 배당소득세율의 상승, 배당률 및 대주주지분율의 상호작용항은 주식수익률과 양(+)의 상관관계를 가지는 것으로 나타나 배당소득세율이 상승할 때 배당률이 높은 기업에서 대주주 지분율이 주식수익률에 미치는 영향을 강화하는 것으로 나타났다. 본 연구의 결과로 볼 때, 기업의 배당정책에 따라 개인투자자의 조세부담을 완화할 수 있어 투자가치에 영향을 미칠 수 있는 것으로 나타났다. 따라서 정책입안자의 입장에서 조세의 형평성을 달성하기 위해서는 소득유형에 따른 차별적 과세를 줄이는 것이 필요할 것으로 생각된다.

This paper empirically investigates the impact of winning a quality award by investigating the rate of return of a firm's stock in the stock market, and by analyzing the contribution and effectiveness to a firm's competitiveness. It also compares the effect of firms winning MB(Malcolm Baldrige) award with that of firms winning Korean quality awards on the stock market. A comparative method is used to analyze the change of award-winning firms'rate of return and then they are classified by time-series, cross-sectional, firm's size, award agency, and the year of receiving the award. The number of firms employed in this study is 74, however, multiple award-winning firms are included in the analysis, which increased the sample size to 118. Results indicate that Korean quality awards improve an award-winning firms'market value but not as much as the MB award did.

The purpose of this research study is to examine the stock market's response to terrorist attacks. The study uses data of terrorist attacks in different parts of the country (Pakistan) from June 1, 2014 to May 31, 2017. The event window procedure applies to a 16-day window in which 5 days before and 10 days after the attack. In addition, several event windows have been built to test the response of the Pakistan Stock Exchange. KSE-100 index is taken as proxy of response. The total terrorist attacks are classified into four categories: attacks on law enforcement agencies, attacks on civilians, attacks on special places and attacks on politicians, government employees and bureaucrats. The standard market model is used to estimate the abnormal return of the Pakistan Stock Exchange, which takes 252 business days each year. Furthermore, BMP test is used to check statistical significance of cumulative abnormal rate of return (CAAR). The results of this study reveal that total number of terrorist attacks and attacks on law enforcement agencies show long-term effects on Pakistan stock exchange. However, attacks on civilians, attacks on special places and attacks on politicians, government employees and bureaucrats have little effect on the Pakistan Stock Exchange.

CAPM explains the rate of return for the risk asset by $\beta$, systematic risk. There are some assumption in CAPM. But CAPM can not explain the movement of stock price sufficiently due to limitation of the assumptions. Therefore many scholars study which variables with the exception of $\beta$ effect on the rate of return of risk asset for supplementing this limitation by using PER, size of firm etc.. But it will be natural that PER, size of firm etc. to be determinant factors of $\beta$ also effect on the abnormal rate of return, because PER, size of firm etc. used in their studies already effect on determination of $\beta$, . That is, the determinant factors of $\beta$ effect on determination of abnormal rate of return according as $\beta$, effects on abnormal rate of return. Therefore, this study tests empirically how the determinant factors of $\beta$, effect on determination of$\beta$, ,and how $\beta$ and the determinant factor of $\beta$ effect on the abnormal rate of return in CAPM.

This paper analyzes the impact of CSR on the capital market in Korea. Using listed firm data, we found that the creation of a sustainability report that indirectly measures the level of CSR can bring the stock rate of return difference of the capital markets representative market index. First, when a firm that publishes a sustainability report was compared in terms of its market rate of return, it showed a return increase of about 2%. We found that higher returns were gained through the competitive advantage of related business when the firm was actively involved in social responsibility. Second, subdivided by industry, firms belonging to the capital goods industry were found to reach a rate of return higher than that of industry. These firms were noticeable in that they were mainly industries that caused environmental pollution. Third, in an additional analysis, foreign investors were given the sustainability report of financial businesses, which was interpreted as a result of industrial properties. A sustainability report is a comprehensive report on the economic, environmental, and social activities of a firm. Firms must learn that they can gain trust through publishing trustworthy reports while achieving the lasting power of growth from the stakeholders.

본 연구에서는 벤처캐피탈협회가 보유하고 있는 VC 펀드 관련 자료를 가지고 VC의 실현된 수익률을 투자약정 수준에서 측정하였다. 또한, 동 자료가 제공하는 자세한 정보를 가지고 국내 최초로 비상장 피투자사의 주가수익률과 분산을 측정할 수 있었다. 분석결과, VC 펀드가 피투자사의 주가수익률보다 높은 실적을 보였다. 또한 VC 펀드가 투자한 스타트업의 경우 분산으로 측정된 총위험과 주가수익률 간에 양의 관계가 존재함을 확인하였다. 마지막으로 이들 기업의 총위험에 기초해 시장이 기대하는 수익률에 비해 측정된 주가수익률은 낮은 수준에 머무르고 있음도 발견하였다. 이는 비록 비상장사 스타트업이 고위험-고수익의 관계를 보장하더라도 개인투자자들이 비상장사에 직접 투자하기를 꺼리게 만드는 한 요인으로 작용할 수 있을 것이다.
