讲座内容:

We propose a model of pre-scheduled announcement with heterogeneous informed traders to examine the determinants of trading volume and pre-announcement premium. Using VIX as a proxy of information uncertainty, we show that changes of VIX during the pre-announcement period have a significant explanatory power of pre-announcement premium. On the other hand, abnormal trading volume has a negative effect on the magnitude of pre-announcement premium. Further decomposing trading activities into informed trading and liquidity shocks, large negative liquidity shocks during the pre-announcement period are also responsible for large excess returns.
