Abstract: The process of security price adjustment to the release of new information has long held the interest of the finance profession, both in academics and in practice. The efficiency of financial markets in reflecting new information significantly impacts the allocation of capital and income within the markets1 and, consequently, can affect social welfare. Thus, public, business, and investment policies are all related to an understanding of the functioning of security markets and their utilization of information. As a result, a significant body of economic research has considered the impact of information upon security markets under a number of alternative market structures. In this paper, we attempt to contribute to this literature by extending previous research in the two related areas of speculation and information dissemination.
