چکیده

در سالهای اخیر با تسریع در روند جهانی شدن و یکپارچگی بازارها، ارتباط میان بازارها به خصوص بازارهای مالی شدت گرفته است به طور‌ی‌که سرریز نوسانات در بازارهای مالی در زمان بحران، دغدغه بسیاری از سرمایه‌گذاران شده است. این موضوع موحب شده، سرمایه‌گذاران برای مدیریت ریسک و انتخاب سبد بهینه دارایی‌ها، بررسی نوسانات، بازده دارایی‌ها و سرریز نوسانات را بیش از پیش اهمیت دهند. در این پژوهش، شدت تأثیرپذیری دارایی‌های مالی بویژه بازار‌های سهام اسلامی و سهام متعارف از یکدیگر در قبل و بعد از بحران کوید 19، با استفاده از داده‌های ‌قیمت نفت، طلا، سهام اسلامی و سهام متعارف و مدل VRMA-BEKK-AGARCH برآورد گردید. نتایج نشان‌دهنده افزایش نسبی میزان سرریز تلاطم و شوک‌ها در دوره بعد از کوید 19 نسبت به دوره قبل آن می‌باشد. نتایج همچنین حاکی از سرریز متقابل و دوطرفه شوک و تلاطم بین تمامی شاخص‌های مورد بررسی در دوره نمونه بعد از کرونا می‌باشد. گرچه بازده صکوک در طول دوره کامل و دو دوره فرعی به طور قابل توجهی نسبت به همتای متعارف خود نوسان کمتری داشته است؛ اما شاخص سهام اسلامی (صکوک) همانند اوراق قرضه متعارف از سرریز نوسانات در بحران کوید 19 تأثیر پذیرفته و تفاوت قابل ملاحظه‌ای در سرریز بین دو بازار در دوره‌های مورد بررسی مشاهده نشده است.
