To test the hypotheses, ۱۰۷ companies were selected from the listed companies in Tehran Securities Exchange by systematic method during the years of ۱۳۸۵ to ۱۳۹۲ and the research variables were analyzed using Excel and Eviews software and Panel data model. The results of obtained from investigating the hypotheses confirm the negative relationship between cash cycle and receivables collection period with profitability. Inventories relationship was significant and positive with profitability and was different from the expected result (Significant positive) which led to the rejection of the hypothesis.
