Publication An Assessment Of Currency Exposure Of Non-financial\r\nFirms In Asean-4: Insights Using The Stock Returns And Cash Flow Methodologies(AESS Publication, 2022) ;Hishamuddin Abdul Wahab ;Obiyathulla Ismath Bacha ;Norhazlina Ibrahim ;Ahmad Monir AbdullahNurul Afaaf Mohd NasirThis study examines the extent and nature of foreign exchange exposure in 405 listed corporations operating in the ASEAN-4 nations, Indonesia, Malaysia, Singapore, and Thailand. The study period of 23 years, from 1995 to 2017, covers the two major crisis periods, the Asian financial crisis (AFC) of 1997 and the global financial crisis (GFC) of 2008. Our study improves on earlier work by using two alternative assessment methods, i.e., stock returns (SR) and cash flow (CF) methods. We report several interesting and noteworthy results. First, we find that the stock returns approach results in a higher incidence of exchange rate exposure relative to the cash flow method. Specifically, about 65% and 28% of the total ASEAN-4 firms had significant exposure to all currencies under the stock returns and cash flow methods, respectively. Second, we find the sample firms to have predominant exposure to the US dollar, signifying the important role played by the United States (US) as the major trading partner of the ASEAN-4. Third, when evaluating time-varying exposure, we find that the incidence of the exchange rate exposure is event-specific. Most of our sample firms were highly exposed to exchange rates during the mid-points of the AFC and the GFC. - Some of the metrics are blocked by yourconsent settings
Publication The Wavelet Multi-Scale Analysis of Exchange Rate Exposure: An Application to Malaysian Consumer Products and Services Sector(Global Academy of Training and Research (GATR) Enterprise, 2023) ;Hishamuddin Abdul WahabNurul Afaaf Mohd NasirObjective - Past efforts in assessing foreign exchange rate exposure assume homogeneity in the level of exposure across time horizons which seems to be impractical due to the dynamic nature of comovement between firm value and exchange rate. Methodology – Given this, the study aimed to investigate the multi-scale relationships between changes in exchange rates and firm values of 56 multinational corporations in the consumer products and services sector from January 2000 to December 2020. Findings – The novelty of the study lies upon the application of Maximal Overlap Discrete Wavelet Transformation (MODWT) method which allows decomposition of a single time series domain into different time domains. The fragmentation into multiple time domains allows the measurement of scale-dependent foreign exchange exposure. As a result, the study discovered a non-monotonic trend for wavelet scale j of currency exposure across time scales. In particular, there was a gradual increase in the magnitude of beta exchange exposure and the proportion of exposed firms from low to high time scales. This finding suggested that firm value is more sensitive to changes in the exchange rate within a widened time domain. Novelty – The study demonstrated on how the wavelet technique can be used to measure foreign exchange risk and aided firm managers and market participants in managing foreign exchange risk for a specific time interval.
