Determinants of Commodity Futures Prices: Decomposition Approach

Abstract: Developing models to analyze time series is a very sophisticated, time-consuming, but interesting experience for researchers. Commodity price component determination is challenging due to remarkable price volatility, uncertainty, and complexity in the futures market. This study aims to determine the components that drive the market price of commodity futures. This study utilized the decomposition methods, empirical mode decomposition (EMD), and variational mode decomposition (VMD), to analyze three commodity f… Show more

“…Notwithstanding, evidence from the empirical literature [8,9,[20][21][22][23][24][25]27] suggest that the flow of information and investor response to such information is not only timedependent but also varies across frequencies. It is instructive to note that frequency-domain analysis is a significant component for investors who operate at different time horizons [28][29][30][31][32][33][34][35][36][37]. Moreover, the stylised facts of fat tails and volatility clustering of financial time series introduce the complexity, asymmetry, and nonlinearity in the behaviour of market participants [20,34,36,38,39].…”

“…The existence of a commodity becomes a necessity that must be available every day to fulfill society's food consumption. In its development, agricultural commodities often experience price fluctuations (Antwi, Gyamfi, Kyei, Gill, & Adam, 2021;Kumari, Venkatesh, Ramakrishna, & Sreenivas, 2019;Nigatu & Adjemian, 2020;Nugroho, Prasada, Putri, Anggrasari, & Sari, 2018;Sativa, Harianto, & Suryana, 2017). Von Braun and Tadesse (2012) stated that natural factors often fluctuate agricultural commodities.…”

“…One of those is applying a GNN to a directed graph 2,13,19,20 and the other is feature pruning using correlation coefficients. [21][22][23][24] GNN theory 20 is a popular choice among teams designing ML-based solutions in which directed graphs are involved. 19 This is especially true for the NFV research area, since concepts of nodes (VNFs), features (resource load), and links between those nodes through a directed graph (SFC) are a direct translation of the underlying concepts of the NFVI.…”

“…Some useful techniques to select input data features prior to ML model training to remove uncorrelated data while avoiding reducing the models' prediction accuracy can be found in the literature. One of those is applying a GNN to a directed graph 2,13,19,20 and the other is feature pruning using correlation coefficients 21‐24 …”
