Research has examined the association between security returns or levels of market value and current cost accounting data as reported under the Securities and Exchange Commission's Accounting Series Release No. 190 (ASR 190) and Statement of Financial Accounting Standards No. 33 (SFAS 33). Cross-section regressions of security returns were estimated on historical cost net income and holding gains. The coefficients on the ASR 190 - SFAS 33 variables were found to be statistically significant at conventional levels. This finding contradicts previous research findings.
