Spillover effect of information arrivals in security trading

Haipeng Xing, Associate Professor, SUNY Stony Brook

NVC 11-217, IS-STA Conference Room

In the standard bivariate mixture distribution model for a single security market, the flow of information arrivals determines the dynamics of stock price volatility and trading volume. Due to the contemporaneous and cross-sectional dependence of information arrivals among several securities, a spillover effect might occur. To model such effect, we extend the mixture distribution hypothesis to the case of multiple securities, and use a latent vector autoregressive process to characterize information arrivals. We further use a stochastic approximation algorithm with Markov chain Monte Carlo method to estimate the dynamics of information arrivals. We apply our models and inference procedure to analyze markets of multiple securities and show the spillover effects in them are significant.
