We find that US cross-listing of Canadian stocks enhances domestic high-frequency trading (HFT) activity in the form of both opportunistic trading and market-making. First, US cross-listing boosts HFT low-latency cross-border arbitrage. This highly correlated HFT arbitrage activity across...

This paper compares three aspects of IPOs on the Toronto Stock Exchange's junior (TSX-V) and senior (TSX) markets: (1) share price performance on the first day and first year, (2) volume on the first day and first year, and (3) days between the predicted IPO date, IPO announcement date and...

I examine 468 estimates on the relationship between trading volume and stock returns reported in 44 studies. I deploy recent nonlinear techniques for detecting publication bias together with Bayesian and frequentist model averaging to evaluate the heterogeneity in the estimates. The results...

We use trade-level data to examine the role of actively managed funds (AMFs) in earnings news dissemination. We find AMFs are drawn to, and participate disproportionately more in, earnings announcements (EAs) that include bundled managerial guidance. When the two pieces of news are directionally...

We examine if differences in short selling volumes and the information impounded by short sells can contribute to explaining pricing differences which exist between the A- and H-share markets in China. In particular, we argue and also find that informed short selling around earnings...

We cross-sectionally analyze the presence of aggregated hidden depth and trade volume in the S&P 500 and identify its key determinants. We find that the spread is the main predictor for a stock's hidden dimension, both in terms of traded and posted liquidity. Our findings moreover suggest that...

We empirically study the trading activity in the electronic on-book segment and in the dealership off-book segment of the London Stock Exchange, investigating separately the trading of active market members and of other market participants which are non-members. We find that (i) the volume...

The effectiveness of any sanction depends on the costs of avoiding its restrictions. We examine whether bearish option strategies were substitutes for short sales during the September 2008 short-sale ban. We find a significant diminution in option volumes and a significant increase in option...

We show that search volume on Google not only serves as an intuitive proxy for overall firm recognition, but also captures the attention of stock market investors. Our results suggest that an increase in search queries is associated with a rise in trading activity and stock liquidity. We...

Recent work considers whether information is simultaneously reflected in both option and equity markets. We provide new evidence supporting Black's (Financ. Anal. J. 31:36–72, 1975) conjecture that information is first revealed in option markets. Specifically, changes in call and put...
