摘要：This research investigates the impact of working capital management (WCM) on the profitability and market performance of firms that constitute an Islamic market index (Karachi Meezan Index [KMI-30]) in Pakistan during 2002–2013. The data have been divided into three parts, that is, preglobal (2002–2007), during (2007–2008), and postglobal financial crisis period (2008–2013), to examine the proposed relationship in different macroeconomic settings. Net trade cycle (NTC) and its components are used to measure the WCM efficiency, while NTC square is used to proxy the impact of excessive holdings of working capital on corporate performance. The econometric models are calculated in a generalized method of moments (GMMs)-based regression environment to ensure the robustness of empirical outcome. The results reveal that, as opposed to conventional businesses, KMI-30 firms are more ethical in their short-term financial management. Besides, such firms adopted a conservative WCM policy during the global financial crisis of 2007–2008. Furthermore, we confirm the presence of a concave relationship between working capital levels and firm performance as NTC is positively, whereas NTC square is negatively, related to firm performance. This article makes a significant contribution to the extant literature as it evaluates the impact of WCM on the profitability and market performance of Islamic market indexed firms under varying macroeconomic conditions.
