Abstract |
This paper investigates the determinants of KOSPI200 futures mispricing by calculating implied spot price. The analysis was centered on the effect of KOSPI200 past return, volatility and skewness on the mispricing. The sample period spans the beginning of 2004 to the ending of 2017. Evidence indicates that KOSPI200 futures-implied spot prices were underpriced, relatively to KOSPI200 spot prices, during the sample period, and the 60 day cumulative past return, volatility and skewness are consistently and statistically significant determinants of KOSPI200 futures mispricing for the nearest and second nearest futures contracts. The results are robust after dividing the sample into two sub-periods. Empirical results lend support to the hypothesis that the past returns’ moments exert effect on the relationship between spot and futures prices, rejecting the joint hypothesis that two markets are weak-form efficient and are integrated. |
