Chordia, Roll and Subrahmanyam (2005, CRS) estimate the speed of convergence to market efficiency based on short-horizon return predictability of the 150 largest NYSE firms. We extend CRS to a broad panel of NYSE stocks and are the first to examine the relation between electronic communication...

We examine the informational efficiency of prices of all exchange traded funds (ETFs) that are actively traded on the NYSE Arca, based on methodology developed by Chordia et al. (2005), and compare the resulting price formation process to that of shares traded on the NYSE and NYSE Arca. Despite...

We analyze all NASDAQ firms with respect to their short-horizon return predictability, which Chordia et al. (2008) formulate as an inverse indicator of market efficiency. Our results confirm that increased liquidity enhances market efficiency, and show that this effect is amplified during...

Chordia, Roll and Subrahmanyam (2008, hereafter CRS) examine short horizon return predictability from past order flows of large, actively traded NYSE firms across three tick size regimes and conclude that higher liquidity facilitates arbitrage trading which enhances market efficiency. We extend...

The purpose of this paper is to investigate the effect of the information disclosure quantity on the pricing efficiency of stocks. Using a sample of large and actively traded Canadian companies listed on the Toronto Stock Exchange, the authors utilize annual reports filed on system for...

We revisit the stock market anomaly documented by Thomas and Zhang (2008) and show that the apparent mispricing of information transfers has decayed over time, as the US markets experienced rapid improvements in the efficiency of the underlying price formation processes. Utilizing recent...

Motivated by recent studies that demonstrate the superiority of the Global Industry Classification System (GICS) relative to the Standard Industry Classification (SIC) system in capital market research, we revisit the stock market anomaly documented by Thomas and Zhang (TZ) ("Overreaction to...

On 23 April 1997, the Toronto Stock Exchange closed its trading floor, making it at that time the second-largest stock exchange in North America to choose a purely electronic trading environment for its equities. Exploiting this natural experiment, we find that the move to electronic trading...
