Abstract: | This study empirically investigates the recent SFAS No. 33 requirements to determine if the inflation disclosures, or information similar to it, are impounded in security returns. An attempt is also made to determine which of the two diverse disclosures best represent the information impomded by the market. The investigation utilizes a methodological framework arising out of currently accepted asset pricing theory. The results suggest that the current cost data parallels the information impounded in security returns and that it provides risk information not included in the commonly employed systematic risk factor, beta. |
