The exercise of a warrant leads to the well-known dilution phenomenon, whose effects have been extensively studied over the last four decades. In contrast, the existing literature has paid inadequate attention to the volatility spillover between stockholders and warrant holders. This...

We investigate the dynamics of the displayed part of the Island ECN limit order book for the equity index-linked securities market around macroeconomic news releases. Our results indicate that the quality of the electronic market, measured by spread and depth, deteriorates during the releases....

This study examines whether differential interpretation of earnings announcements is affected by earnings and firm characteristics. We find that Kandel and Pearson's (1995) forecast measures of differential interpretation are: 1) negatively related to earnings predictability, firm size, and...

Rational herd behavior and informationally efficient security prices have long been considered to be mutually exclusive but for exceptional cases. In this paper we describe the conditions on the underlying information structure that are necessary and sufficient for informational herding and...

One of the central hypotheses of behavioural finance is that stock prices systematically overreact. The seminal study is DeBondt and Thaler (1985), which appears to show that past winners (stocks that have earned the highest positive abnormal returns during the pre-formation period) tend to...

This paper investigates informed trading on stock volatility in the option market. Using a unique data set from the Chicago Board Options Exchange, we construct non-market maker net demand for stock volatility from the trading volume of individual equity options. We find that this volatility...

We present a simple, Glosten-Milgrom type equilibrium model to analyze the decision of informed traders on whether to use limit or market orders. We show that even after incorporating an order's price impact, not only may informed traders prefer to use limit orders, but the probability that they...

We propose a new structural form methodology for understanding the fluctuations and predictability of volatilities and covariances of asset returns. In our model, a representative agent learns about the joint movements in inflation and real earnings through business cycles. We extract investors'...

Several analytical models explain post-earnings-announcement drift, momentum and mean-reversion by making assumptions about investor behavior. They posit that investors react more strongly as a series of similar earnings surprises continues. Related literature suggests that behavior should vary...

This paper analyzes trade-initiation by small and large traders for one year following earnings announcements and examines the predictive ability of event-time trading for future returns. With earnings surprises based on a seasonal random walk expectations model, small traders react slightly...
