The Fama–French pricing model with dynamic factors (DFPM) extracted via the Kalman filter from the six size and book-to-market portfolios has a good performance in understanding stock returns. Using international stock market data, we find that the DFPM significantly improves the...

The dynamic betas for ten Canadian sector portfolios using the Kalman filter approach are estimated herein and are found to be best described by a mix of the random walk (trend) and mean-reverting (cycle) processes. The relative importance of the trend and cycle components of sector betas is...

Using intradaily order flows processed via the Lee and Ready (1991) algorithm for NYSE/AMEX-listed stocks over the past 27 years, I estimate a set of price-impact parameters. The results provide strong evidence that price impact is priced in the cross-section of stock returns, even after...

In this study, we employ order imbalance measures to provide evidence that there exists an individual/institutional dichotomy in reactions to seasoned equity offerings (SEOs). The evidence supports the notion that small, possibly naıve, individual investors keep trading SEO stocks...

We develop a model to analyze the effects of hedging activities by options market makers (OMMs) facing informed trading. The model suggests that OMMs׳ hedging activities motivated by adverse-selection risk lead to wider spreads in both stock and options markets. The hedging effect on spreads is...

Many proxies of illiquidity have been used in the literature that relates illiquidity to asset prices. These proxies have been motivated from an empirical standpoint. In this study, we approach liquidity estimation from a theoretical perspective. Our method explicitly recognizes the analytic...

In this study, we employ order imbalance measures to provide evidence that there is cross-sectional heterogeneity in investor reactions to seasoned equity offerings (SEOs). The normally positive relation between imbalances and returns disappears for trade number imbalances but remains intact for...

We claim that regressing excess returns on one-lagged volatility provides only a limited picture of the dynamic effect of idiosyncratic risk, which tends to be persistent over time. By correcting for the serial correlation in idiosyncratic volatility, we find that idiosyncratic volatility has a...

We provide empirical evidence on the impact of limited market participation on the informational role played by institutions and analysts in the market. Our findings are as follow. First, the price adjustment of stocks that are favored by institutions and analysts and associated with low...
