چکیده

مفهوم بهره ­وری سرمایه به اندازه ­گیری توان مدیریت در استفاده بهینه از سرمایه به عنوان یکی از منابع مهم و محدود شرکت می ­پردازدو طبیعی است که سهام شرکت ­های با بهره ­وری سرمایۀ بالا، بازده بالاتری نیز داشته باشند و همچنین قدرت توضیح دهندگی مدل های ارائه شده جهت پیش­بینی بازده سهام با استفاده از بهره­ وری سرمایه افزایش یابد. هدف این مطالعه، بررسی چگونگی تأثیر بهره ­وری سرمایه بر قدرت توضیح دهندگی مدل های پیش­بینی بازده سهام و همچنین بررسی این تأثیر در مراحل مختلف چرخه عمر شرکت ها است. نسبت سود عملیاتی به سرمایه ی سرمایه گذاری شدۀ شرکت(ROIC) به عنوان شاخص بهره­ وری سرمایه و از مدل های سه عاملی فاما و فرنچ (1993) و پنج عاملی فاما و فرنچ (2013) به عنوان مدل های پیش بینی بازده سهام و از روش جریان­ های نقدی دیکنسون(2011) جهت طبقه بندی چرخه عمرشرکت ها استفاده شده است. دورۀ مورد مطالعه، سال های 1384 الی 1394 است و نمونه ی انتخابی110 شرکت از میان شرکت های پذیرفته شده در بورس اوراق بهادار تهران و با ویژگی های تعریف شده، می باشد. نتایج حاصل از آزمون فرضیه ها نشان می دهد که بهره ­وری سرمایه بر رابطه بین عامل بازار و رشد با صرف ریسک در تمام مراحل چرخه عمر تأثیر دارد ولی بر رابطه بین عامل اندازه با صرف ریسک فقط در مرحله بلوغ تأثیر معنادار دارد.

چکیده [English]

Capital productivity concerns the measurement of management power in making optimal use of capital as one of the important and limited company resources. In companies with highly efficient capital productivity, stocks are expected to offer higher returns and the explanatory power of the models proposed to predict stock returns is assumed to increase. The purpose of this study was, thus, to examine the extent to which capital productivity might influence the explanatory power of stock market predictive models and to scrutinize this viable effect at various stages of corporate life cycle. The Operating Profit Ratio (ROIC) was used to operationalize Capital productivity, the Tripartite Factor Model (Fama & Franch, 1993) and the Pentagonal Factor Model (Fama & Franch, 2013) were employed to predict stock returns and corporate life cycle was categorized via the Dickinson Cash Flow (2011). The research sample comprised 110 companies with specific descriptive characteristics selected from among all those listed on the Tehran Stock Exchange during a ten-year period from 2005 to 1394. The results of the hypothesis testing analyses demonstrated that capital productivity affects the relationship between market factor and risk-free growth at all stages of the life cycle, but size was found significantly correlated with risk merely at the maturity stage of the life cycle.
