New study reveals varying risks in agricultural commodity investments
The article analyzes the risk of investing in agricultural commodities like Wheat, Cocoa, and Cotton using Value at Risk (VaR) and Expected Shortfall (ES). The researchers used a time series model approach, specifically ARIMA for predicting price movements and GARCH for volatility. They found that Cotton has the lowest risk based on VaR, while Cocoa has the highest. However, based on ES, Cocoa has the lowest risk and Cotton has the highest.
