چکیده

عدم تشخیص حباب‌های قیمت دارایی و نوع آن (یگانه و چندگانه) موجب اثرات مخربی بر اقتصاد می‌شود. ابزارهای اقتصادی جدید، نه تنها تحلیل رفتار انفجاری ملایم حباب را ممکن گردانیده؛ بلکه تعیین تاریخ شروع و خاتمه آنها را نیز مهیا کرده است.
هدف مطالعه حاضر کشف حباب‌های قیمت بورس اوراق بهادار تهران و شرکت فرابورس ایران و تعیین تاریخ‌های شروع، انفجار و محو کامل حباب در دوره 01/1389 تا 01/1395 است. در این راستا از شاخص‌ کل، شاخص صنعت، شاخص50 شرکت و شاخص کل فرابورس استفاده شد. نتایج تحقیق نشان دهنده آن است که بازار بورس 2 دوره حبابی و فرابورس 5 دوره حبابی را تجربه کرده‌اند. نتایج همچنین نشان دهنده این است که بازارهای بورس و فرابورس به ترتیب در 59% و 57% بازه مورد مطالعه حبابی بوده‌اند. به عبارت دیگر در بیش از نیمی از دوره مورد بررسی، حباب وجود داشته که بیانگر بی‌ثباتی زیاد قیمت‌های سهام است.
