Top Traders Unplugged — OI20: Why Commodities Refuse to Trend Forever

Host: Moritz Siebert
Guest: Doug King, hedge fund manager, commodity trader, and owner of Coventry Football Club
Date: December 24, 2025

Overview

This episode explores the cyclical nature of commodity markets, why enduring trends in commodities are rare, and how experienced traders adapt to constant change. Guest Doug King shares insights from decades of trading—both physical and derivative markets—along with candid perspectives on risk management, edge, and the realities of running a fundamental commodity hedge fund. The discussion is rich with trading philosophy, market anecdotes, lessons from major trades, and the unique challenges (and rewards) of managing concentrated commodity positions.

Key Discussion Points & Insights

1. Doug King’s Background ([01:24]–[04:49])

• From mathematics and engineering to Cargill, Doug’s early career focused on grains and physical commodities.
• Became global head of petroleum trading at Cargill, then co-founded Merchant Commodity Fund in 2004.
• Diversified into physical commodity trading (RCMA Group), later moving primarily to the hedge fund and an oilseed processing venture.
• Also owns Coventry Football Club, emphasizing parallels between trading commodities and trading football players.

“In the hedge fund we trade commodities, and with the football club we trade players. So it’s kind of all the same, but different.”
—Doug King [04:45]

2. The Cycle that Won’t Die: Commodities Never Trend Forever ([06:17]–[14:07])

• Every commodities supercycle eventually breaks down due to innovation and substitution:
  • Shale Oil Boom shocked the industry and capped previous bullish oil cycles.
  • GMO Seeds have kept food supply above population growth trends.
• Doug stresses cycles: bullish narratives are often overturned by innovation, with prices returning to similar levels decades later.

“Commodities, I think, are quite disappointing in respect to constantly moving upwards. So it’s always cyclical.”
—Doug King [13:05]

• Current focus: electrification theme (copper, lithium) where supply/demand imbalances may be more persistent due to inelastic supply.

3. Fund Philosophy and Why Buy-And-Hold Doesn’t Work ([14:07]–[15:38])

• Passive investing in commodity indices or ETFs leads to wealth destruction due to rolling losses, contango, and lack of real trend.
• King critiques the launch of USO/UNG commodities ETFs as likely to lose all investor money in the long run.

“That’s how you lose all your money…if you’d invested there and just closed your eyes, you’d lost all your money, and then some more.”
—Doug King [14:58]

4. What Is the Fund’s Edge? Fundamental, Not Quantitative ([15:38]–[18:37])

• The approach: deep bottom-up supply/demand research, close connection to physical markets, and a strong grasp of cash vs. derivatives.
• Edge comes from experience, judgment, and avoiding data myopia (not just tracking every ship or tank).

“All the experiences that I have led and my team has led through all the cycles, all the moments, all the experience and still being there, getting the returns people want. That to me is where I would answer the question—I’m probably decent at what I do.”
—Doug King [17:49]

5. Risk Management and Position Sizing ([19:53]–[24:57])

• The fund isn’t forced to be invested everywhere all the time; it seeks “stories” (themes) and can be highly concentrated if risk protocols allow.
• Strong discipline: uses drawdown-based risk budgeting, scales back dramatically when underperforming, and never “shoots it back” after losses.
• Volatility control is paramount, especially in wild markets (e.g. cocoa’s surge, WTI going negative); large moves often driven by margin stress, not fundamentals.

“There’ll be moments where we will have rocket ship moments where distortions come and you’ve got to be in it.”
—Doug King [21:07]

6. Physical vs. Derivatives: When Owning Real Commodities Matters ([18:37]–[19:45], [28:34]–[30:14])

• The fund has on occasion taken physical delivery to test its views or exploit cash/futures convergence—examples include natural rubber and sugar.
• Physical insights can add conviction, mitigate risk, and sometimes reveal a disconnect between market narrative and “basis” reality.

7. Iconic Trades—Both Best and Worst ([30:44]–[35:16])

• 2014 Oil Crash: King’s team went against consensus, shorting oil before a major price collapse. Success owed to fundamental questioning of GDP and shale supply.
• LME Nickel Squeeze: Fund made gains on the rally, but LME’s unprecedented decision to cancel trades due to volatility led to lost profits and frustration.

“It’s never happened before—how can they actually cancel a futures trade when they’ve opened the market? That was disappointing for us.”
—Doug King [34:20]

8. Lessons from the Physical Trading House (RCMA) ([35:56]–[39:44])

• RCMA Group was acquired to supply physical market intelligence and diversify income.
• Though logical, maintaining a trading house brought challenges: operational and counterparty risks, confusing outsiders, and ultimately not worth the effort.
• The fund still prioritizes physical/cash market information over derivatives for edge, especially in filtering “noise.”

“The key thing in trading is what’s your filter, what’s relevant, what’s not relevant…noise removal.”
—Doug King [40:37]

9. Culture, Recruitment, and Trading Organization ([44:20]–[46:18])

• Doug contrasts his fund’s environment with platform funds like Millennium, noting the ultra high pressure and short leashes at larger firms.
• His fund offers a longer-term, more trusting environment for skilled traders focused on fundamentals and robust risk.
• Talent can always be found, but approach and fit matter.

“You go to Millennium…you are on the tightest leash of your life. You better start well, you better not have any slippage at all…”
—Doug King [44:53]

Notable Quotes & Memorable Moments (with Timestamps)

• On Why Commodities Won’t Trend Forever:
  “Commodities are disappointing in respect to constantly moving upwards. So it’s always a cyclical…here we are 20 years later and we’re similar pricing because of the innovations and substitutions.”
  —Doug King [13:05]

• On Buy-and-Hold Commodity Exposure:
  “All of it, everything gone, especially USO.”
  —Doug King on commodity ETFs [14:58]

• On Managing Concentrated Risk:
  “If there’s no excitement…we don’t want to be wasting any of our risk bullets. We should be grinding out a good return…But there’ll be moments where we will have rocket ship moments where distortions come and you’ve got to be in it.”
  —Doug King [21:07]

• On Breaking Consensus:
  “We did our own thing…that was a pretty interesting one…we were right. Global growth did disappoint, surpluses started to build meaningfully at high pricing points, and then OPEC…decided they’d had enough of shale growth and we’re going to have a price war.”
  —Doug King (2014 Oil Crash) [32:34]

• On Physical Trading Reality:
  “We talk to people in physical. We don’t talk to the derivative industry, we talk to the physical industry. That is where we value the information.”
  —Doug King [39:44]

Conclusion

Doug King delivers a masterclass in commodities thinking: robust, grounded in cycles, always skeptical of narratives, and anchored in the physical supply/demand. For King, the job isn’t trend-riding or predicting new paradigms, but understanding when the market is real—and when it’s driven by distortions, margin calls, or financial speculation. Edge comes from experience, deep market study, and a healthy disregard for hype. In both football and commodities, the winners are those who understand value—and when the cycle is about to flip.
