| Abstract: | This study investigates the impact of the experimental standard, SSAP16 (Current Cost Accounting), on share returns on the London stock market. Approximately 200 companies were examined between 1980–84. The experimental design specifies current cost as a supplementary signal to historical cost and employs two main statistical tools: ordinary least squares regression and the abnormal performance metric. In addition, a number of different CCA measurements are specified in order to assess the sensitivity of the results and to ease comparison with other studies. The results suggest that CCA information has a small but significant impact on stock returns in the days up to announcement. However, CCA does not seem to be the main driving force behind long period returns. Returns in the long run are associated more closely with historical cost information than with that generated by SSAPI6. |
