This paper is concerned with investigating the information content of undisclosed limit orders, identifying factors that affect their sizes, and examining brokers’ behavior in using undisclosed orders. Our estimation results from a sample stocks listed on the ASX indicate that the size of undisclosed orders are affected by a number of factors. Given the ‘stealth trading’ pattern observed in large disclosed limit orders, this paper provides evidence to support a similar pattern in the case of undisclosed limit orders as well. Our model also provides a statistical measure for estimating the size of undisclosed orders.
