Cash flow bullwhip effect (CFB) is the amplification of working capital variance along a supply chain. High CFB is a sign of inefficient working capital (WC) management and can lead to a significant reduction in financial resilience. CFB can be used as a measure of a company’s ability to manage operational risks and corresponding resilience. We investigate the existence of CFB and the traditional bullwhip effect (BWE) in a sample of 238 semiconductor companies over 2010-Q1 to 2020-Q4. These companies' average CFB and BWE are 3.95 and 2.77, respectively. We find that CFB and BWE of a semiconductor company are negatively associated with company size, degree of seasonality in demand, and company’s payment policy conservativeness; and positively associated with procurement and payment lead times.
