Abstract:
The objectives of this research were to study the influence of traditional accounting measures, the interaction of non-financial information and traditional accounting measures, intangible assets, and macroeconomic factors affecting stock prices. The research population comprised 269 listed companies with complete data spanning six years, from 2017 to 2022. This timeframe covered both pre-pandemic and pandemic periods of COVID-19. The data underwent analysis using fixed-effects multiple regression equations. The findings revealed that (1) three traditional accounting measures - earnings per share, book value per share, and net cash flow from operating activities per share - exerted a positive influence on stock prices. Overall, earnings per share had the most relevance. However, during the COVID-19 outbreak, including in some tested equations, book value per share was found to be more relevant than other traditional accounting measures. (2) The level of corporate governance quality complemented the value relevance of earnings per share and book value per share, tested with both March and April closing prices. The interaction with earnings per share had more influence on book value per share. (3) Sustainability awards did not increase the value relevance during pooled period testing; however, sustainability awards increased the value relevance of earnings per share before the COVID-19 outbreak only. (4) Integrated report did not improve the value relevance in all tested periods, including the test with the closing prices of securities in April. (5) The type or size of the audit firm did not increase the value relevance during the pooled period; however, it complemented the value relevance of book value per share only during the COVID-19 pandemic. The auditor's opinion did not increase the value relevance, during pooled period using March and April closing prices. However, it complemented the value relevance of book value per share only during the COVID-19 pandemic. (6) Intangible assets per share were irrelevant in all tested periods, including testing with the closing prices in March and April. (7) Macroeconomic factors influencing the value of securities were Gross Domestic Product and Business Sentiment Index, both of which had a negative influence on the stock prices. The Consumer Price Index had a positive influence. Additionally, regarding the control variables, the size of the firm negatively impacted the stock prices during only the COVID-19 pandemic.
