Pairs trading is a type of arbitrage investment strategy that buys an underpriced security and simultaneously sells an overpriced security. Since the 1980s, investors have recognized pairs trading as a promising arbitrage strategy that pursues absolute returns rather than relative profits. Thus, individual and institutional traders, as well as hedge fund traders in the financial markets, have an interest in developing a pairs trading strategy. This study proposes pairs trading rules (PTRs) created from a price ratio between securities (i.e., stock index futures) using rough set analysis. The price ratio involves calculating the closing price of one security and dividing it by the closing price of another security and generating Buy or Sell signals according to whether the ratio is increasing or decreasing. In this empirical study, we generate PTRs through rough set analysis applied to various technical indicators derived from the price ratio between KOSPI 200 and S&P 500 index futures. The proposed trading rules for pairs trading indicate high profits in the futures market.

본 연구는 KOSPI200 시장을 대상으로 2003년 1월 1일부터 2013년 6월 30일까지의 일별자료를 이용하여 ETF 시장, KOSPI200 현물시장 그리고 선물시장에서의 가격발견효과에 대해 실증분석 하였다. 본 논문의 주요 분석결과는 다음과 같이 요약된다. 우선 KODEX200(KOSEF200), KOSPI200 현물 그리고 선물은 모두 공적분 관계가 있는 것으로 나타났으며, 이들 시장 간에는 예상대로 상호연관이 있음을 발견하였다. VECM을 이용하여 가격발견효과에 대한 분석에서는 ETF시장의 대표종목인 KODEX200이 KOSPI200 현물시장과 선물시장보다 가격발견기능이 우월한 것으로 나타났다. 거래량이 상대적으로 적은 KOSEF200의 경우 현물시장에 대해서는 가격발견효과가 없었지만, 선물시장에 대해서는 가격발견효과가 통계적으로 10% 유의수준에서 존재하는 것으로 나타났다.

국내 자본시장의 개방으로 주가변동에 따른 위험분산 외국의 단기성자금에 의한 국내증권시장의 교란을 억제하고 투자활성화를 위해 도입된 주가지수선물의 헤징은 다른 종류의 금융선물 및 상품선물거래 도입을 촉진하게 될 것이고 이는 결국 국내 금융기관 국제경쟁력을 높이고 우리 금융시장 선진화를 앞당기는데 기여할 것이다. 또한 위험분산기능과가격발전기능을 통해 경제안정과 경제활동 원활화에도 큰 도움을 줄 것으로 기대된다. 결국주가지수선물시대가 열림에 따라 국내 주식시장에 따라 지수편입종목의 거래량 확대, 선물지수의 변동으로 초래될 주식시장의 변화에 대해서도 보다 높은 관심을 가져야 할 것으로 판단된다.

This study uses the benchmark interest rate of the Federal Open Market Committee (FOMC) to predict gold futures prices. For the predictions, we used the support vector machine (SVM) (a machine-learning model) and the long short-term memory (LSTM) deep-learning model. We found that the LSTM method is more accurate than the SVM method. Moreover, we applied the Boruta algorithm to demonstrate that the FOMC benchmark interest rates correlate with gold futures.

This paper proposes quantitative investment strategies for KOSPI200 index futures using VKOSPI and control chart. Stochastic control chart is employed to decide when to take a position as well as what position out of long and short should be taken by monitoring whether VKOSPI or difference of VKOSPI touches the control limit lines. The strategies include 4 approaches, which are traditional control chart and 2-Area control chart coupled with VKOSPI and its difference, respectively. Computational experiments using real KOSPI200 futures index for recent 3 years are conducted to show the excellence of the proposed investment strategies under control chart framework.

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.

When the margin level is set relatively low, margin violation probability increases and the default probability of the futures market rises. On the other hand, if the margin level is set high, the margin violation probability decreases, but the futures market becomes less attractive to hedgers as the investor's opportunity cost increases. In this paper, we investigate whether the movement of KOSPI200(Korea Composite Stock Price Index 200) futures daily prices can be modeled with the extreme value theory. Base on this investigation, we examine the validity of the margin level set by the extreme value theory. Computational results are presented to compare the extreme value distribution and the empirical distribution of margin violation in KOSPI200. Some observations and implications drawn from the computational experiment are also discussed.

A new approach to the commodity futures term structure model is introduced. The most salient feature of this model is that, once the interest rate model is given, the commodity futures price volatility is the only quantity that completely determines the model. As a consequence this model enables one to do away with the drudgeries of having to deal with the convenience yield altogether, which has been the most thorny point so far.

This article examines the information transmission process between the KOSPI 200 futures market and its underlying stock market, using the 10-second quote and trade data. The VAR analysis reveals that quote revisions through limit orders in general lead trades through market orders. In addition, the VAR analysis shows that the futures market tends to lead the stock market in terms of quote revisions and trades, even though the other direction is also observable. Even when we focus on the events causing large movements in quote revisions and trades, those lead and lag relations between those markets and between quote revisions and order imbalances are confirmed.

This paper examines the relationship between the stock and futures markets in terms of lead-lag relationship, correlation and the hedge ratio using wavelet analysis. The basic finding is that the relationship between the two markets significantly depends on the time-scale. First, there is a feedback relationship between the stock and futures markets in the long-run scale; however, weaker evidence is observed in shorter-run scales. Second, wavelet correlation between the two markets increases for a longer time scale. Third, the hedge ratio and the effectiveness of hedging strategies increase as the investment horizon gets longer. The results in this paper indicate that the stock and futures series are perfectly correlated in the long run and are tied together over long horizons.
