This study aims to show the risk reduction effects of round-the-clock trading environment. We analyse the trading results of the currency futures contracts in CME Globex which are open 23 hours a day. These include Euro FX, Japanese Yen, Australian Dollar, and British Pound from January 2005 to August 2013. We generate new price series using only daytime prices during about 7-hour period. This hypothetical "G" data series may have greater gap risk than the original "R" data series. Empirical results show the trading risk reduction effects, that is R data series have higher profits and lower risks than G data series.

The core decisions of bulk shipping businesses can be summarized as the timing and the choice of period for which carrying capacity is traded. In particular, frequent decisions to trade freight either with repeated spot transactions or with a one-off long-term deal critically impact business performance. Even though a variety of freight trading strategies can be employed to facilitate the decisions, chartering practitioners have not been active in utilizing these strategies, and academic research has rarely proposed applicable solutions. The specific properties of freight as a tradable commodity are not properly reflected in existing studies, and limitations have been reported in their application to the real world. This research focused on the establishment of applicable freight trading strategies by taking into account two properties of freight: time perishability and term-dependant pricing. In addition to traditional trading strategies, artificial neural networks were applied for the first time to the test of freight trading strategies. The performances of the trading strategies were measured and compared to produce a remarkable outperformance of the ANN. This research is expected to make a significant contribution to chartering practices by enhancing the quality of chartering decisions and eventually enabling the effective management of freight rate risk. In addition to methodological expansion, the result will propose a way to approach the controversial issue of freight market efficiency.

This paper deals with the application of the genetic algorithm to the technical trading rule of the stock market. MACD(Moving Average Convergence & Divergence) and the Stochastic techniques are widely used technical trading rules in the financial markets. But, it is necessary to determine the parameters of these trading rules in order to use the trading rules. We use the genetic algorithm to obtain the appropriate values of the parameters. We use the daily KOSPI data of eight years during January 1995 and October 2002 as the experimental data. We divide the total experimental period into learning period and testing period. The genetic algorithm determines the values of parameters for the trading rules during the teaming period and we test the performance of the algorithm during the testing period with the determined parameters. Also, we compare the return of the genetic algorithm with the returns of buy-hold strategy and risk-free asset. From the experiment, we can see that the genetic algorithm outperforms the other strategies. Thus, we can conclude that genetic algorithm can be used successfully to the technical trading rule.

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.

As number of cyber traders are growing, the uses of technical analyzing indicators in trading increase as well. Parabolic SAR, which indicates changes of trend in the market, is one of the most used indicators by cyber traders. Especially when a market shows a specific trend, it is very useful. However, this indicator often gives late signals and shows less trustful ones in a stable market. This paper proposes a method that give more conservative signals by a composition of Parabolic SAR and Moving Average. The experiment will compare the earning rates of using only Parabolic SAR strategy and of using a composition strategy of Parabolic SAR and Moving Average.

The present study aimed to propose the competitive strategy to fashion brand franchise stores by analyzing articles regarding success stores as published in fashion magazines. A total of 91 articles were selected from three fashion magazines and content analysis was applied to extract major factors. Four types of trading areas and eight product types were compared by the major factors. As results, six major factors composing competitive strategy were analyzed such as personal selling, management of sales forces, promotion, customer relationship management, management of store space, and relationship with headquarter. Comparing competitive factors by the types of trading area, management of sales forces and personal selling were crucial for central district and for outlets/interchange district. On the other hand, personal selling and customer relationship management were important for local district while management of store space and personal selling were critical for tenants of the large discount store/shopping mall area. Comparing by product types, personal selling was the most important factor for all product types except young casualwear whereas the second important one was management of sales forces for adult casualwear, womenbbbs wear, and others. For menbbbs wear, sales promotion was the second important one whereas management of store space was the second crucial one for underwear and childrenbbbs clothing. Based on the present study result, it is proposed that competitive strategy of individual fashion brand franchise store should be differently developed because the characteristics of trading area and product type are different and in turn, customers benefit and competition might be different.

투자자들은 증권회사가 제공하는 시세표인 Limit Order Book 정보를 통해 국내외 투자자들이 제출하는 주문 정보를 실시간으로 파악하면서 거래에 참여하고 있다. Limit Order Book에 실시간으로 공개되고 있는 주문 정보가 주가 예측에서 유용성이 있을까? 본 연구는 장 중 투자자들의 매수와 매도 주문이 어느 한쪽으로 쏠리면서 주문 불균형이 나타나는 경우 미래 주가 등락의 예측 변수로서 유의성이 있는지를 분석하는 것이다. 분류 알고리즘을 이용하여 주문 불균형 정보의 당일 종가 등락에 대한 예측 정확도를 높이고, 예측 결과를 이용한 데이트레이딩 전략을 제안하며 실증분석을 통해 투자 성과를 분석한다. 자료는 2004년 1월 19일부터 2022년 6월 30일까지의 4,564일 동안의 코스피200 주가지수선물 5 분 봉 주가를 분석하였다. 실증분석 결과는 다음과 같다. 첫째, 총매수 주문량과 총매도 주문량의 불균형 정도로 측정하는 주문 불균형지수와 주가는 유의적 상관성을 보인다. 둘째, 주문 불균형 정보는 당일 종가까지의 미래 주가 등락에 대해서도 유의적인 영향력이 나타났다. 셋째, 주문 불균형 정보를 이용한 당일 종가 등락의 예측 정확도는 Support Vector Machines 알고리즘이 54.1%로 가장 높게 나타났다. 넷째, 하루 중 이른 시점에서 측정한 주문 불균형지수가 늦은 시점에서 측정한 주문 불균형지수보다 예측 정확성이 더 높았다. 다섯째, 종가 등락 예측 결과를 이용한 데이트레이딩 전략의 투자 성과는 비교모형의 투자 성과보다 높게 나타났다. 여섯째, 분류 알고리즘을 이용한 투자 성과는 K-Nearest Neighbor 알고리즘을 제외하면 모두 비교모형보다 총수익 평균이 높게 나타났다. 일곱째, Logistic Regression, Random Forest, Support Vector Machines, XGBoost 알고리즘의 예측 결과를 이용한 데이트레이딩 전략의 투자 성과는 수익성과 위험성을 동시에 평가하는 샤프비율에서도 비교모형보다 높은 결과를 보여주었다. 본 연구는 Limit Order Book 정보 중 총매수 주문량과 총매도 주문량 정보의 경제적 가치가 존재함을 밝혔다는 점에서 기존의 연구와 학술적 차별점을 갖는다. 본 연구의 실증분석 결과는 시장 참여자들에게 투자 전략적 측면에서 함의가 있다고 판단된다. 향후 연구에서는 최근 활발히 연구가 진행되고 있는 딥러닝 모형 등으로의 확장을 통해 주가 예측의 정확도를 높임으로써 데이트레이딩 투자전략의 성과를 개선할 필요가 있다.

기존의 알고리즘 트레이딩 시스템에서는 투자전략을 금융사가 제공하는 프로그램밍 언어와 API들을 사용하여 사용자가 직접 프로그래밍 하여야 했기에 일반 투자자들이 사용하기에는 많은 어려움이 있어왔다. 따라서 본 논문에서는 사용자가 프로그래밍에 대한 지식이 없어도 손쉽게 자신의 투자전략을 사용자 인터페이스를 통하여 제시하면 이를 통하여 알고리즘이 형성되어 시스템 트레이딩이 수행되도록 하는 사용자 친화적인 트레이딩 시스템을 개발하는 것을 목적으로 한다. 본 시스템은 금융회사의 서버와 주식 정보를 송수신하고 매매를 수행하는 서버 부분과 투자전략을 설정하기 위한 보조지표들로 이루어진 사용자 인터페이스, 이를 기반으로 알고리즘이 생성되는 부분 등으로 구성되어진 클라이언트로 구성되어진다. 제안된 시스템은 모의 투자 실행을 통하여 사용자가 설정한 투자전략에 따라 설정된 알고리즘에 의하여 자동으로 매매가 이루어짐을 통하여 성능을 검증하였다.

This study investigates the relationship between stock index and its associated nearby futures markets based on the cost-of-carry model. The purpose of this study is to explore the existence of mispriced futures contracts, and to test whether traders can earn trading profits in real financial market using the information about the mispriced futures contracts. This study suggests the concordance correlation coefficient to investigate the existence of mispriced futures contracts. The concordance correlation coefficient gives a desirable result for trading profits that results from a comparative analysis among profits from trading at the time to indicate trading opportunities determined by the degree of the difference between the observed market price and the theoretical price of a futures contract. In addition, this study also explains that the concordance correlation coefficient developed from the mean square error (MSE) has a statistically theoretical meaning. In conclusion, this study shows that the concordance correlation coefficient is appropriate for analyzing the relationship between the observed stock index futures market price and the theoretical stock index futures price derived from the cost-of-carry model.
