Negative stock returns, artificial intelligence, machine learning algorithms, Conservative reporting, Tehran Stock ExchangeAbstract
Predicting the occurrence of negative stock returns is a central issue in behavioral finance and risk management, playing a critical role in improving investment decision-making and enhancing capital market efficiency. This study employs advanced artificial intelligence algorithms, including artificial neural networks, support vector machines, decision trees, and AI-based optimization algorithms, to develop models for forecasting negative stock returns. These algorithms, with their ability to learn complex patterns and uncover nonlinear relationships among financial data, demonstrate significantly better performance than traditional methods in the early detection of negative return risks. Financial and reporting data from companies listed on the Tehran Stock Exchange were collected over a five-year period, and variables related to conservative financial reporting were incorporated into the analysis. Statistical analyses and performance evaluations of 101 listed companies during the period 2010 to 2015 indicate that conservative reporting—by emphasizing the early recognition of losses and moderating profit recognition behaviors—has a significant impact on improving the accuracy and generalizability of AI models in predicting the risk of negative returns. The findings suggest that integrating intelligent approaches with conservative reporting measures can enhance the quality of financial information, reduce uncertainty, and increase transparency in investment decisions. This research not only deepens scientific understanding of the relationship between conservative financial reporting and stock return risk but also offers practical applications for financial analysts, managers, and capital market policymakers.
