چکیده مقاله :
هدف: هدف اين پژوهش، بررسی رابطه بین افشای اطلاعات مالی آیندهنگرانه و نوسانات بازده سهام شرکتهای پذیرفتهشده در بورس اوراق بهادار تهران و نیز بررسی اثر حسن شهرت شرکتها بر این رابطه است. روششناسی: در راستاي تحقق هدفهاي پژوهش دو فرضیه تدوين شده است كه معنادار بودن رابطه بين افشای اطلاعات مالی آیندهنگرانه، نوسانات بازده سهام و حسن شهرت را در شرکتهای پذیرفتهشده در بورس اوراق بهادار تهران، مورد آزمون قرار ميدهد. افشاء اطلاعات مالی آیندهنگرانه، با استفاده از روش تحلیل محتوا اندازهگیری شد. روش آماري مورداستفاده جهت آزمون فرضيههاي مطرحشده در اين پژوهش، روش تجزیهوتحلیل رگرسیون گامبهگام و نمونه آماري پژوهش شامل 120 شرکت - سال در سالهای 1397 الی 1401 است. یافتهها: نتایج حاصل از تجزیهوتحلیل فرضيههاي پژوهش نشان ميدهد که افشای اطلاعات مالی آیندهنگرانه، منجر به کاهش نوسانات بازده سهام شرکتهای پذیرفتهشده در بورس اوراق بهادار تهران میگردد. همچنین، افشای اطلاعات مالی آیندهنگرانه توسط شرکتهای با شهرت بالاتر (در مقابل شرکتهای با شهرت پایینتر)، دارای اثر بیشتری بر کاهش نوسانات بازده سهام است. دانش افزایی: با تحلیل تأثیر اطلاعات مالی آیندهنگر بر نوسانات بازده سهام، تحقیقات پیشین را گسترش میدهد.
Purpose: The purpose of this research is to investigate the relationship between the disclosure of prospective financial information and the volatility of stock returns of companies listed on the Tehran Stock Exchange, as well as to investigate the effect of companies' good reputation on this relationship. Methodology: In order to achieve the goals of the research, two hypotheses have been developed that test the meaningfulness of the relationship between the disclosure of prospective financial information, the fluctuations of stock returns and good reputation in the companies listed on the Tehran Stock Exchange. Disclosure of prospective financial information was measured using content analysis method. The statistical method used to test the hypotheses presented in this research is the step-by-step regression analysis method, and the statistical sample of the research includes 120 companies in the years 2018 to 2022. Findings: The results of the analysis of the research hypotheses show that the disclosure of forward-looking financial information leads to a decrease in the volatility of stock returns of companies listed on the Tehran Stock Exchange. Also, disclosure of forward-looking financial information by firms with higher reputations (as opposed to firms with lower reputations) has a greater effect on reducing stock return volatility. Originality: By analyzing the effect of forward-looking financial information on the volatility of stock returns, it expands previous research.
