Informed and Uninformed Trading in an Electronic, Order-Driven Environment.

The purpose of our study is to investigate the trading behavior of informed and uninformed investors in a screen-based, order-driven environment. As more and more exchanges conduct trading through electronic limit-order books, it is increasingly important to analyze consequent trading behavior and its impact on the liquidity provision process. We examine one of the largest electronic, order-driven markets in the world, the Stock Exchange of Hong Kong. Our findings show that the interaction of informed and uninformed traders plays a significant role in determining corporate liquidity. Copyright 2000 by MIT Press.
