  • This paper examines the price discovery role of the KOSPI 200 futures index for its cash index. It was used the intrady data for KOSPI 200 and futures index from July 1998 to June 2001. The existing Preceding study for KOSPI 200 futures index was used the data of early market installation, but this study is distinguished to use a recent data accompanied with the great volume of transaction and various investors. We established three hypothesis to examine whether there is the price discovery role in the KOPSI 200 futures index and the characteristics of that. First, to examine whether the lead-lag relation is induced by the infrequent trading of component stocks, observations are sorted by the size of the trading volume of cash index. In a low trading volume, the long lead time is reported and the short lead time in a high volume. It is explained that the infrequent trading effect have an influence on the price discovery role. Second, to examine whether the lead-lag relation is different under bad news and good news, observations are sorted by the sign and size of cash index returns. In a bad news the long lead time is reported and the short lead time in a good news. This is explained by the restriction of"short selling" of the cash index Third, we compared estimates of the lead and lag relationships on the expiration day with those on days prior to expiration using a minute-to-minute data. The futures-to-spot lead time on the expiration day was at least as long as other days Prior to expiration, suggesting that "expiration day effects" did not demonstrate a temporal character substantially different form earlier days. Thus, while arbitrage activity may be presumed to be the greatest at expiration, such arbitrage transactions were not sufficiently strong or Pervasive to alter the empirical price relationship for the entire day. for the entire day.

  • 본 연구는 1982년부터 1996년까지의 유로달러선물과 T-bill 선물의 일별 시계열 자료를 이용하여 단기금리선물의 가격발견기능을 실증적으로 검정하고 있다. 분석방법은 시계열의 불안정성 여부를 알아보는 단위근검정, 장기균형관계를 알아보는 Johansen 공적분검정, 공적분관계가 있는 시장에 대해 설정오류의 문제를 피하고 변수들간의 인과관계를 파악하기 위해 Granger 인과관계모형을 사용하였다. 주요한 결과로 각 금리시계열들은 일차누적 시계열 I(1)임이 확인되었고 공적분관계를 분석한 결과, 각 금리 시계열의 선형결합은 안정적인 장기균형관계가 있음을 나타내 주고 있다. 따라서 각 시장은 서로 밀접한 인과관계가 있음을 암시하고 있다. 또한 선물금리와 현물금리를 대상으로 인과관계검정 결과 유로달러시장의 경우 전기에서는 피드백효과가 있고 후기에는 선물금리의 가격발견기능이 나타났다. T-bill 시장의 경우는 전기에 현물금리가 선물금리에 대해 선행하였고 후기에는 피드백효과가 나타났다. 이렇게 유로달러선물이 후기에서 가격발견기능이 있는 것은 정보통신의 발달과 유로시장의 적은 규제 등으로 유로달러선물시장이 1980년대 후반부터 급성장한 것이 그 원인으로 분석된다.

  • 본 연구는 옵션가격 및 거래량 자료를 이용하여 옵션시장의 가격발견 기능에 대해서 분석을 시도하였다. 이를 위해 먼저 옵션가격과 거래량 정보가 현물시장을 선행하는 현상에 대해서 분석해 보았다. 옵션가격은 실제 현물지수를 약 1시간 정도 선행하는 것으로 관찰되었다. 콜옵션 가격이 풋옵션에 비해서 상대적으로 옵션시장에서 높게 거래되는 경우 이는 현물주식시장에서의 주가상승을 예고하는 것으로 나타났다. 옵션 거래량 정보 역시 현물시장의 가격움직임을 예측하는데 유효한 것으로 관찰되었다. 콜옵션의 풋옵션 대비 상대적인 거래증가는 투자자의 낙관적인 장세전망을 반영해 일단 현물지수의 상승을 야기하는 것으로 나타났으나 이후 투자자의 풋옵션을 통한 헤지(hedge) 수요의 증가로 이어지는 것으로 조사되었다. 두 번째로 본 연구는 이러한 옵션시장의 가격발견 기능을 이용하여 매매전략을 수립하고 이를 통하여 투자이익을 극대화시킬 수 있는지에 대해서 살펴보았다. 콜옵션 가격(거래량)이 풋옵션 가격(거래량)에 비해 고평가(증가) 되었을 경우 이는 주가상승을 미리 예고하고 있는 신호로 받아들어져 주식을 매입하고 반대로 콜옵션 가격(거래량)이 풋옵션 가격(거래량)에 비해 저평가(감소) 되었다면 주가하락을 예측하기 때문에 주식을 매도함으로써 투자이익을 증대시킬 수 있을 것이다. 실증분석 결과는 우선 옵션 가격정보를 이용하여 현물시장에서 지수 바스켓 포트폴리오를 매매하려는 전략은 30분 내외의 단기 투자에는 유효하나 그 이상의 투자기간을 가지는 경우에는 예상과는 다른 결과를 초래하였다. 반면 옵션시장에서의 콜옵션과 풋옵션의 상대적인 거래량 정보는 현물주식시장의 움직임을 예측하는데 옵션 가격정보에 비해서 보다 효과적인 것으로 판단되었다. 조사한 모든 일중 및 1일(overnight) 투자수익률에서 옵션 거래량의 상대적 비율에 의거한 투자전략은 통계적으로 유의한 투자수익률의 차이를 가져왔다.

  • The purpose of this paper was to examine the dynamics of the price discovery function between lean hog futures and spot markets using the vector error correction model (VECM). The researcher also investigated the existence of the long-run equilibrium relationship between the lean hog futures and spot markets. Daily time series data of lean hog futures and spot observed in the Korean market during the period from 5 Jan. 2011 to 28 Dec. 2012 were analyzed. To examine the price discovery, this study employed the Gonzalo and Granger's (1995) information ratio and Hasbrock's (1995) information ratio measurement method. The significant findings of the study are summarized as follows. First, lean hog futures and spot market are significantly correlated. Secondly, the lean hog future market plays a more dominant role in price discovery than the spot market. Finally, price discovery measures based on the VECM suggested that the lean hog future market plays a more dominant role in price discovery than the lean hog spot market. This is the important systematic empirical work to find the relationship between the lean hog future and spot market.

  • Using high-frequency data for 2 years, this study investigates intraday lead-lag relationship between stock index and stock index futures markets in Korea and China. We found that there are some differences in price discovery and volatility transmission between Korea and China after the stock index futures markets was introduced. Following Stoll-Whaley(1990) and Chan(1992), the multiple regression is estimated to examine the lead-lag patterns between the two markets by Newey-West's(1987) heteroskedasticity and autocorrelation consistent covariance matrix(HAC matrix). Empirical results of KOSPI 200 shows that the futures market leads the cash market and weak evidence that the cash market leads the futures market. New market information disseminates in the futures market before the stock market with index arbitrageurs then stepping in quickly to bring the cost-of-carry relation back into alignment. The regression tests for the conditional volatility which is estimated using EGARCH model do not show that there is a clear pattern of the futures market leading the stock market in terms of the volatility even though controlling nonsynchronous trading effects. This implies that information in price innovations that originate in the futures market is transmitted to the volatility of the cash market. Empirical results of CSI 300 shows that the cash market is found to play a more dominant role in the price discovery process after the Chinese index started a sharp decline immediately after the stock index futures were introduced. The new stock index futures markets does not function well in its price discovery performance at its infancy stage, apparently due to high barriers to entry into this emerging futures markets. Based on EGAECH model, the results uncover strong bi-directional dependence in the intraday volatility of both markets.

  • The price relationship between the futures market and the underlying spot market has attracted the attention of academics, practitioners, and regulators due to their roles during periods of turbulence in financial markets. The purpose of this paper is to investigate the dynamic of price relationship(or lead-lag relationship) between Korean Treasury Bond futures market and spot market. To examine the nature of the price relationship, descriptive statistics, serial correlation, and cross-correlation are used as a preliminary statistics in the Korean Treasury Bond spot and futures market. Next, following Stoll-Whaley(1990) and Chan(1992), the multiple regression method is used to examine the lead-lag patterns between the two markets. The empirical results are summarized as follows. The mean returns of spot markets and future markets are positive(+) and negative(-) respectively and the standard deviation of both stock and futures returns increase through the sub-periods. For the most periods, there is negative skewness in the both markets. The zero excess kurtosis due to the heavy tails of the distribution are relatively large. The autocorrelations in the spot returns for the sample periods are positive in time lag 1, but the autocorrelations in the future returns shows no significant evidence. The results of the daily cross-correlations between the KTB spot and futures returns indicate that a lead-lag relationship don't exist for price changes of futures and spot markets as a preliminary analysis. Finally, empirical results of regression analysis for both market indicate that there is no evidence that the KTB futures lead the KTB spot market, or the KTB spot market lead the KTB futures market. These results are robust for all sub-periods.
