This study considers a new stochastic volatility model, in which 디지몬 카드 게임 sign and magnitude of stock returns play roles in explaining a substantially detailed relationship between stock returns and volatility. 디지몬 카드 게임 proposed model allows for threshold and leverage effects, and accommodates three regimes (i.e., large negative return; mid-range, including moderate negative and positive returns; and large positive return) to better capture 디지몬 카드 게임 time-varying aspect of 디지몬 카드 게임 leverage effect. Applications of 디지몬 카드 게임 proposed model on 디지몬 카드 게임 return series of 디지몬 카드 게임 S&P 500 Index and Microsoft Corporation suggest that 디지몬 카드 게임 relationship between stock returns and volatility depends on 디지몬 카드 게임 magnitude of 디지몬 카드 게임 returns and 디지몬 카드 게임ir signs. 디지몬 카드 게임 comparison of 디지몬 카드 게임 deviance information criterion for various stochastic volatility models reveals a good fit of 디지몬 카드 게임 proposed model for 디지몬 카드 게임 data.
