We examine which group of investorsindividuals, institutions, or foreignershas more information about the true price process in the Korea Stock Price Index 200 (KOSPI 200) options market. Using the Hasbrouck (1995) information share and the Gonzalo and Granger (1995) common factor weight approach, we show that foreigners are the most informative about the efficient price process, and domestic institutional investors as well as individual investors have small contribution to price discovery. This result holds firmly, even after controlling for the effects of trading volume and the number of trades. Our empirical results suggest that foreigners are informed traders in the KOSPI 200 options market, consistent with the findings of Ahn, Kang, and Ryu (2008)
