چکیده
این پژوهش با هدف تحلیل تأثیر تجدید ارائه صورت‌های مالی بر واکنش بازار سهام و بررسی نقش تعدیل‌گر احساسات سرمایه‌گذاران در بورس اوراق بهادار تهران، با استفاده از داده‌های ترکیبی شرکت‌های پذیرفته‌شده طی دوره زمانی ۱۳۹۳ تا ۱۴۰۳ و به‌کارگیری مدل رگرسیونی با اثرات ثابت انجام شد. یافته‌ها نشان داد تجدید ارائه صورت‌های مالی تأثیری منفی و معنادار بر بازده غیرعادی تجمعی سهام دارد. این نتیجه همسو با نظریه اطلاعات نامتقارن و مدل علامت‌دهی است و حاکی از آن است که تجدید ارائه به‌عنوان علامتی از کاهش کیفیت اطلاعات مالی، اعتماد سرمایه‌گذاران را کاهش داده و منجر به افت قیمت سهام می‌شود. همچنین، احساسات سرمایه‌گذاران نقشی تعدیل‌گر معنادار ایفا می‌کند؛ به‌گونه‌ای که در دوره‌های دارای سطح بالای احساسات، واکنش منفی بازار به تجدید ارائه تشدید می‌شود. علاوه بر این، ویژگی‌های بنیادی شرکت (اندازه، سودآوری و شفافیت اطلاعاتی) نیز واکنش بازار را تعدیل نمودند؛ شرکت‌های کوچک‌تر، کم‌سودآورتر و با شفافیت اطلاعاتی پایین‌تر، واکنش منفی شدیدتری به تجدید ارائه نشان دادند که این امر از نظریه‌های نقدشوندگی و ریسک شرکتی حمایت می‌کند. در مجموع، نتایج به‌طور قوی نشان می‌دهد که تجدید ارائه صورت‌های مالی به‌عنوان یک علامت منفی، واکنش منفی بازار را به‌دنبال دارد و شدت این واکنش تحت تأثیر قابل‌توجه احساسات سرمایه‌گذاران و ویژگی‌های بنیادی شرکت قرار می‌گیرد.

چکیده English

 This study aims to analyze the impact of financial restatements on the stock market reaction and to examine the moderating role of investor sentiment in the Tehran Stock Exchange. Using panel data from listed companies during the period 2014 to 2024 and applying a fixed effects regression model, the findings indicate that financial restatements have a negative and significant effect on cumulative abnormal stock returns. This result is consistent with asymmetric information theory and signaling theory, suggesting that restatements, as a signal of reduced financial reporting quality, diminish investor confidence and lead to stock price declines. Furthermore, investor sentiment plays a significant moderating role; during periods of high sentiment, the market’s negative reaction to restatements is intensified. In addition, firm fundamentals (size, profitability, and information transparency) also moderated the market reaction; smaller, less profitable firms with lower transparency experienced a stronger negative reaction, supporting liquidity and firm risk theories. Overall, the results strongly indicate that financial restatements serve as a negative signal, prompting adverse market reactions, and that the intensity of this reaction is significantly influenced by investor sentiment and firm fundamentals.
