OI20: Why Commodities Refuse to Trend Forever ft. Doug King
Top Traders Unplugged
Concentration, risk limits and portfolio construction
Doug details position limits, typical number of strategies, and how concentration focuses on a few themes at a time.
Moritz Siebert speaks with Doug King about what it really means to trade commodities through cycles, distortions, and stress. Drawing on decades at Cargill and more than twenty years running a commodities hedge fund, Doug explains why innovation keeps scarcity narratives in check, why commodities resist buy and hold logic, and how real edge comes from cash markets rather than futures screens. He reflects on defining trades in oil, nickel, and agriculture, the limits of volatility targeting, and the discipline required to survive violent squeezes. The result is a grounded account of conviction, risk control, and why commodities reward patience more than prediction.
