Abstract
Since the volume of corporate information disclosures is constantly increasing, this study seeks to distinguish information with a "text" nature from information with a "numbers" nature to examine the existence and the direction of the volume of these two types of information on the efficiency of the stock price formation in companies. This study also deals with the effect that the volume of these two types of disclosed information have on each other in the process of price formation. However, it does not concentrate on the quality of the content of accounting information and its usefulness. The research sample consists of 169 companies listed on the Tehran Stock Exchange in 1397 (Iranian calendar). Research hypotheses were tested cross-sectionally using ordinary least squares regression. The results revealed that the amount of disclosed information, whether in the form of "text" or "numbers," in general, does not significantly affect the efficiency of the process of the companies' stock price formation in the Iranian capital market. Also, the volume of these two types of information cannot strengthen the influence of each other on the efficiency of the stock price formation process. In addition to expanding the accounting literature in the areas of "disclosure" and "market efficiency," the results of this study contain significant achievements for policymakers, analysts, shareholders, and company managers regarding the volume of information disclosure. The users' ability and the disclosure quality are also some other factors that should be considered when deciding whether to increase the volume of disclosure.
