Abstract

The paper investigates what effect Working Capital Management has on firms’ profitability by using the data from listed companies on Vietnamese Stock Exchange. The sample is collected from 127 public companies for the period of 9 years from 2006 to 2014. The research uses four variables to represent Working Capital Management, which are Day of Sales Outstanding (DSO), Day Sales of Inventories (DSI), Day of Payables Outstanding (DPO), and Cash Conversion Cycle (CCC). Moreover, in order to robust the result, the study also takes into the account the following variables: “Leverage, Growth, Tangibility, Size, Industrial Factors, and Macroeconomic Effects”, which were proven to have significant effects on firms’ profitability. The result implies that there is no correlation between Working Capital Management and firms’ profitability. Hence the conclusion is that Working Capital Management can help companies solve the short-term obligations and improve the efficiency by improving the supply chain and credit policies, however it has nothing to do with firms’ profitability of the companies in the sample.
