This study investigates the convergence process toward efficiency of daily top losers. We find that significance of order imbalance coefficients decreases with increasing time interval, indicating evidences on convergence to market efficiency. A time-varying GARCH model is employed to examine...

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...

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 investigates the empirical relation between order imbalance and intraday NTD/USD exchange rate dynamics. Using one-year high frequency data, we demonstrate that interbank order imbalances have substantial explanatory power for concurrent exchange rate returns both on the daily and...

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...

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...
