Insider trading remains a critical concern for the integrity and fairness of financial markets. This observational study aims to investigate patterns of insider trading in the Athens Stock Exchange (ASE) by analyzing abnormal stock price movements, trading volumes, and key financial disclosures. Utilizing data from a range of publicly traded companies on the ASE, the study applies statistical models and financial metrics to identify potential instances of insider trading. By focusing on periods preceding major announcements such as mergers, acquisitions, and earnings reports, the research highlights any irregular trading behaviors. The results are evaluated in the context of regulatory frameworks and market efficiency, offering insights into the effectiveness of existing surveillance mechanisms in detecting and deterring insider trading. This study contributes to the broader discourse on market transparency, providing policy recommendations aimed at enhancing the detection and prevention of illegal trading activities within the ASE.
