چکیده کسب سود بیشتر، یکی از مهمترین عواملی است که سرمایهگذاران را به سرمایهگذاری در بورس اوراق بهادار تشویق میکند. به دلیل عدم اطمینان موجود در بازار بورس اوراق بهادار و تأثیر آن بر سرمایهگذاری، در این پژوهش به بررسی اهمیت استراتژی جنبش حرکتی (مومنتوم) پرداخته شد. بر این اساس با توجه به جامعه آماری و نیز محدودیتهای درنظرگرفته شده 48 شرکت پذیرفتهشده در بورس اوراق بهادار تهران برای دورهای 6 ساله از سال 1387 تا 1392 مورد بررسی قرار گرفتند. نتایج تحلیل دادهها نشان میدهد که بیشتر استراتژیهای معاملاتی اوراق بهادار، پرتفوی برنده ریسک سیستماتیک بالاتری را نسبت به پرتفوی بازنده نشان میدهند. همچنین، در دوره شش ماهه بیشترین بازدهی اضافی ناشی از بهکارگیری استراتژی مومنتوم ایجاد شده است که در این دوره رابطه بین ریسک سیستماتیک و بازدهی بسیار قوی است.
