This research aimed to analyze the momentum strategy of foreign investors with the smallest trading transactions in the Indonesian stock market. This study applied a quantitative method approach using intraday transaction data of companies listed on the LQ-45 Index for March, April, and May 2017, obtained from the Indonesia Capital Market Institute (TICMI) which is a subsidiary of the Indonesia Stock Exchange (IDX). The number of companies with available data is 35 companies, consisting of 23 non-government stocks and 12 government stocks. The number of observations from the 35 companies was 8,686,030 observations where the government companies recorded 2,751, 545 and the non-government companies 1,387,016 observations. All data was then squeezed and grouped into small, medium, and large trade transaction orders. The data analysis method used was paired t-test with SPSS to analyze cumulative abnormal returns in the formulation and test periods. This study found that small foreign investors carried out momentum strategies on stocks listed on the LQ-45 Index. However, re-testing was done by separating government and non-government shares. It turned out that small foreign investors performed a momentum strategy on non-government and a contrarian strategy on government.

Purpose - This study investigates how earnings volatility influences current stock price informativeness about expectations of future earnings. Design/methodology/approach - I adopt the FERC model developed by Collins et al. (1994) and modified by Lundholm and Myers (2002) to investigate the connection between earnings volatility and future earnings reflected in current returns. I define five-year rolling standard deviations of earnings and components as earnings volatility measures and the degree of deviation of earnings from cash flows over the same five-year, which is developed by Jayaraman (2008). Finding - My results show that earnings volatility delays current stock price response to future operation expectations. They also verify that as earnings are more divergent from cash flows, current returns are less timely incorporating value-relevant future operation. Research implications or Originality This study shows that when volatile earnings deliver obscure and unreliable information about future operation expectations, they cause the market to be conflicting in understandings their implications and make it difficult in attaining correct future cashflow estimates.

한국 생명보험산업에 있어서 정보화투자 효과분석은 향후 정보화투자의 방향설정과 관련하여 매우 중요하다. 이를 위해서 본 연구는 생명보험산업의 다생산물결합 비용함수를 테일러 전개한 제2차 초월대수비용함수를 사용하여 SURE방법으로 정보화자본스톡의 비용탄력성을 추정하였다. 분석자료는 총 33개 생보사를 대상으로 1991-2003년간의 패널자료를 사용하였다. 분석결과는 정보화투자 효과가 개별생보사 마다 차이는 있으나 분석대상 생보사들의 절반정도는 정보화투자로 비용이 절감되는 것으로 나타났다. 한편, 대형생보사는 정보자본스톡이 증가하면, 대형생보사의 비용은 감소하는 것으로 제시되었으나, 중소형생보사와 외국계생보사는 정보자본스톡이 증가할수록 비용이 증가하는 것으로 제시되었다. 또한, 정보예산이 증가할수록 정보자본과 전산직원을 동시에 증가시키고 있으나, 정보자본의 가격이 전산직원의 가격보다 더 크게 하락함에 따라 정보자본을 전산직원 보다 더 크게 증가시키는 것으로 나타났다.

The research aims to analyze the firm-specific and macroeconomic factors that affect insurance company's financial performance. The research explores the variables that influence the financial performance of the United Arab Emirates (UAE)' insurance companies. The analysis for determining financial performance considers the following variables: the firm's age, retention ratio, capital adequacy, underwriting risk/loss ratio, financial-leverage, reinsurance dependency, and macro-economic factors such as GDP per capita, inflation rate considered as independent factors. The return-on-asset (ROA) is the key measuring indicator; it is regarded as the dependent variable for financial performance measures. The research focuses on secondary information obtained from insurance companies' financial statements. The researcher targeted 18 insurance companies listed on the UAE stock exchanges for study purposes. The research examines the overall factors that influence the financial performance of an insurance company. For analysis of data, software package of social sciences (SPSS version 20) is used. The studies used correlation and multiple linear regression analysis to determine financial performance and their effects. The analysis suggests that there are important and constructive relationships between the size, capital adequacy, and reinsurance dependency, while loss ratio, retention ratio, and financial leverage indicate a major negative relationship. And there's no link between GDP per capita and inflation.

This study aims to examine and measure the impact of capital structure on the profitability of companies in emerging markets. The research sample includes eighteen rubber companies listed on the Vietnam stock exchange from 2015-2019. After collecting the research data, it was imported into excel to calculate the criteria for the research model. By using Stata 16 software, the study selected a data processing model and evaluated the relevance of the regression analysis model. The research results show that the profitability of listed rubber companies in Vietnam (measured by return on equity (ROE) has a positive relationship with the debt-to-asset ratio but has a negative relationship with the long-term debt-to-asset ratio. The results also show a positive impact of firm size and revenue growth on profitability while liquidity and the ratio of tangible fixed assets to total assets do not affect significantly. These results are consistent with most of the previously published studies. However, in contrast to many previous studies, our study shows that the long-term debt-to-assets ratio has a negative effect on profitability while the debt-to-asset ratio has a positive effect. This is entirely consistent with the characteristics of long-term debt use in emerging markets.

본 연구에서는 IT산업의 연구개발 투자가 부가가치에 미치는 영향을 분석하기 위하여 IT산업을 방송통신기기, 정보기기, 전자부품으로 세분하고, 각 세부 산업별로 자본스톡, 노동투입, 연구개발스톡을 독립변수로 설정하여 다중회귀분석을 실시하였다. 분석 결과, 모든 산업부문에서 t-value와 R-square 값들은 유의한 것으로 나타났지만, 자기상관은 매우 높게 나타났다. 한편 정보기기산업에서는 연구개발스톡, 전자부품산업에서는 노통투입의 계수 값이 마이너스로 나타나서 다중공선성의 징후가 의심되었다. 본 연구에서는 Cochrane-Orcutt 절차와 주성분회귀분석을 통하여 자기상관 및 다중공선성의 문제를 해결하였다. 연구개발스톡이 부가가치에 미치는 영향을 분석한 결과, 방송통신기기산업의 연구개발투자가 정보기기산업이나 전자부품산업에 비해 훨씬 큰 영향을 미치는 것으로 추정되었다.

본 연구는 기업의 CP 등급변화가 주가의 비정상수익률에 미치는 영향을 분석하였다. 분석결과 기업의 CP 등급 변화는 주가의 비정상수익률에 영향을 미치는 것으로 나타났다. 즉, CP의 등급이 상승한 경우에는 비정상수익률이 향상되고, CP의 등급이 하락하면 비정상수익률이 하락하는 것으로 나타났다. 그리고 기업의 당기순이익이 큰 기업이 등급이 상승되고, 당기순이익이 적은 기업은 등급이 하락하는 것으로 분석되었다. 또한 기업의 CP 등급 변화시 부채비율이 큰 기업이 등급이 상승되고, 부채비율이 낮은 기업은 등급이 상승하는 것으로 나타났다. 그러나 기업의 주주지분율의 크기. 기업의 기업가치의 크기, 기업의 현금흐름의 크기, 기업의 금융비융 부담률의 크기는 주식의 비정상수익률과 관계가 없는 것으로 나타났다. 본 연구는 기업의 CP 변화에 관한 정보가 자본시장에 미치는 영향을 분석한 것으로 의의가 있다. 그러나 표본기업과 공시시점의 선정에 한계가 있다.

본 연구에서는 지방신문사 소유 자본의 성격과 역사에 따라 언론과 지역사회 엘리트간의 네트워킹이 어떻게 형성되어 있는지를 살펴보았다. 이를 위해 2002년 10월 현재, 우리나라에서 발행되고 있는 지방신문 중에서 20개를 선정하며 간부들과 엘리트간의 네트워킹 현상을 분석하였다. 본 연구를 통해 신문사의 경영진 구성은 소유자본의 특성과 역사를 반영한다는 결론을 얻었다. 우선 주식(향토기업)자본 신문사의 경우 지역사회 자본가들이 대거 참여함으로 해서 권력구조와 네트워킹이 긴밀하게 형성되고 있었다. 반면에 가계자본 신문사 간부들은 엘리트들과 밀접한 네트워킹을 형성하지 않은 것으로 나타났다. 대기업자본의 신문사들은 주로 경제 엘리트와의 관련성이 높았다. 도민주자본 신문사의 경우 지역사회 엘리트들과 부분적인 연결망을 형성하고 있었다. 한편 역사라는 변수도 신문사와 엘리트간의 네트워킹을 설명하는데 있어서 중요한 변수로 작용하고 있음을 발견하였다. 역사가 짧은 신문사의 경우 엘리트와 사회적 연결망을 형성하고 있는 비율이 상대적으로 높았으며, 권력구조의 다양한 엘리트 집단과 중복해서 네트워킹을 형성하고 있었다.

International capital movement has made progress at global liberalization of finance and foreign exchange, international monetary norm changing into floating exchange rate system, easiness of collection of information and trade at improvement of information communication technology from early of 1970's. Results of empirical test for relation between foreign exchange rate or various determination factors of foreign exchange rate and interest rate are followed by next sentences. First, according to relation between foreign exchange rate and interest rate, correlation for each of variables after OECD entrance is increased. But, long-term & short-term interest rate is affected by Hanbo & Kia's bankruptcy, continuous large scale corporates bankruptcy and crisis of foreign exchange. Therefore, financial instability is occured. If portfolio investment fund has been inflow as it is mollified by continuous shortage of foreign exchange and fall of country's credit rating, it is expected to have positive effect for long-term & short-term interest rate from appreciation of won against dollar. Second, results from relation between determination factor of foreign exchange rate and interest rate are followed by next sentences. If surplus of current account and goods account is continued, yield of corporate bond is to be stable. But, margin of surplus is expected to diminish after second quarter 98, and difference between external and domestic interest (after adjusting foreign exchange rate) is to be diminished. And if net inflows of foreign investor's fund (stock and bond) is diminished, it is to have negative effect for yield of corporate bond. According to foreign investor's investment movement of previous years, hedge fund were stayed at least during two years in Mexico. It means that sudden capital outflow is not to be happened at Korea. But if external factors from depreciation of yen and China's renminbi are instable, interest rate is expected to increase from capital's outflows. Third, if it is to decrease instability of foreign exchange rate from increase in surplus of future current account, credit rating's upwardness, stability of yen and renminbi, foreign exchange rate is expected to be stable. It is expected to have continuous stability from short-term interest rate to long-term interest rate in this empirical test.
