We investigate bank stock and option transmissions during the financial crisis in 2008. Contemporaneous and lagged-one stock order imbalances have a significant impact on option returns. A time-varying GARCH model is employed to confirm the results. We develop an imbalance-based call (put)...

We use order imbalance to investigate dynamic relations among intraday return, volatility and order imbalance of stock spinoffs. A GARCH model is employed to examine whether the larger order imbalance is associated with larger stock price volatility. We do not find a significant positive...

Many researches indicate informed trading during Leveraged buy-out (LBO) processes. In this study, we examine intraday dynamic relations between order imbalance, volatility and stock returns. The dynamic relation between volatility and order imbalances by a time-varying GARCH model is...

This paper uses four asymmetric generalized autoregressive conditional heteroskedasticity (GARCH) models, which are GJR-GARCH, NA-GARCH, Threshold GARCH (T-GARCH), and AV-GARCH to compare their performance on value-at-risk (VaR) forecasting to the symmetric GARCH model. In addition, we adopt...
