THE INTERACTION OF WORKING AND SPECULATIVE COMMODITY STOCKS AgEcon
Carter, Colin A.; Revoredo-Giha, Cesar.
This paper models the interaction of working (also called pipeline) and speculative commodity stocks. We model working inventories (i.e., raw material inventories carried by processors) based on Ramey’s (1989) model of inventories as factors of production, which allows us to represent storage under inter-temporal price backwardation, observed in commodity markets. We incorporate both speculative and working stocks in a simple model to analyze the interaction and to simulate the relationship between inter-temporal commodity price spreads and stocks. Our model replicates common price patters found in commodity markets.

TECHNICAL ANALYSIS IN COMMODITY MARKETS: RISK, RETURNS, AND VALUE AgEcon
Roberts, Matthew C..
Although there is little academic research that supports the usefulness of technical analysis, its use remains widespread in commodity markets. Much prior research into technical analysis suffered from data-snooping biases. Using genetic programming, ex ante optimal technical trading strategies are identified. Because they are mechanically generated from simple arithmetic operators, they are free of the data-snooping bias common in technical analysis research. These rules are clearly capable of forecasting periods of high and low volatility, but rules generated for corn and soybeans cannot consistently generate profits in the presence of transactions costs. Rules generated for wheat futures produce profits that are weakly significant, both...
