The collapse of many large corporations (such as WorldCom, Tyco, and Enron) has greatly reduced public confidence in the stability of financial markets. Therefore, many studies examined the causes of stock price crash risk, and the results of these studies indicated that the main reason for stock price crash risk is the hiding of bad news, resulting from agency problems, information asymmetry between internal and external parties, and financial reporting opacity. Since improving the financial reporting environment can reduce stock price crash risk, this improvement can be achieved by applying International Financial Reporting Standards. The application of these standards increases financial reporting transparency, reduces information asymmetry in capital markets, enhances comparability across countries, attracts foreign capital inflows, and reduces the cost of capital. Voluntary and mandatory risk disclosure may reduce stock price crash risk as it reduces information asymmetry. In addition, higher audit quality may reduce stock price crash risk and increase the level and quality of risk disclosure; therefore, audit quality may influence the relationship between mandatory risk disclosure and stock price crash risk.
This study aimed to (1) test the relationship between applying the Egyptian Accounting Standards )issued in 2019( and stock price crash risk, (2) test the relationship between mandatory risk disclosure and stock price crash risk, (3) measure the impact of audit quality on the relationship between mandatory risk disclosure and stock price crash risk. In order to achieve the objectives of this study, the study included two aspects, theoretical and empirical.
In the theoretical aspect, the second chapter contained the concept, determinants, and measures of stock price crash risk and the relationship between applying the Egyptian Accounting Standards and stock price crash risk. The third chapter contained the concepts of risk and risk disclosure, the importance of risk disclosure, theories explaining risk disclosure, and corporate governance and its relationship to risk disclosure. This chapter also provides information on risk disclosure according to the rules for listing and delisting securities in the Egyptian Stock Exchange, risk recognition, financial risk measures, Egyptian Accounting Standards related to risk disclosure, methods and techniques of risk disclosure measurement, and the relationship between risk disclosure and stock price crash risk.
In the empirical study, using a sample of 120 observations for non-financial listed firms on the EGX100 EWI during 2020 and 2021, the hypotheses of the study were tested. The results of testing the first hypothesis indicated that there is a significant negative relationship between applying the Egyptian Accounting Standards )issued in 2019( and stock price crash risk. The results of testing the second hypothesis indicated that there is a negative but insignificant relationship between mandatory risk disclosure and stock price crash risk. Finally, the results of testing the third hypothesis indicated that in the companies audited by auditor affiliates with international Big 4 audit firms, there is a significant negative relationship between mandatory risk disclosure and stock price crash risk.
