Commodity Risk Management for Traders

Commodity markets present unique risks that require specialized management techniques. The volatility and leverage involved demand disciplined risk control.

Unique Risks in Commodities

Leverage Risk

• Futures contracts require small margin relative to notional value
• A single crude oil contract controls $70,000+ of oil
• Initial margin may be only $5,000-8,000 (7-10% of notional)
• This magnifies both profits and losses enormously

Gap Risk

• Commodity markets close overnight (unlike forex)
• Weekend events can cause significant gaps
• OPEC decisions, weather events, geopolitical crises
• Your stop loss may not execute at your intended price

Limit Move Risk

• Some commodity exchanges have daily price limits
• "Lock limit" means no trading until the next session
• You cannot exit your position during a locked limit move
• Multiple consecutive limit moves can cause catastrophic losses

Roll Risk

• Futures contracts expire and must be rolled to the next month
• Rolling costs money in contango markets
• Liquidity decreases as expiration approaches
• First notice day can force physical delivery

Position Sizing for Commodities

The ATR Method

• Calculate Average True Range (ATR) for the commodity
• ATR measures typical daily price movement
• Set stops at 1.5-2x ATR from entry
• Size position so 2x ATR loss = 1-2% of account

Dollar Volatility Sizing

• Calculate the dollar value of average daily movement
• Example: Gold ATR = $20, contract = 100 oz, daily vol = $2,000
• If max risk is $2,000 per trade, you can trade 1 contract
• Adjust for each commodity's specific volatility

Correlation Adjustment

• Many commodities are correlated (oil and gas, grains together)
• If you hold 3 correlated positions, your real risk is 3x
• Treat correlated positions as a single risk block
• Reduce individual position sizes when holding multiple correlated trades

Stop Loss Strategies

Volatility-Based Stops

• Use ATR multiples rather than fixed dollar amounts
• Wide enough to avoid noise, tight enough to protect capital
• Adjust stop width for each commodity's volatility profile

Time-Based Stops

• If a trade has not moved in your direction within X days, exit
• Especially useful for seasonal and event-driven trades
• Opportunity cost of capital sitting in a stagnant trade

Structural Stops

• Place stops beyond significant technical levels
• Below support for longs, above resistance for shorts
• If the level breaks, your thesis is invalidated

Portfolio-Level Risk

Maximum Portfolio Heat

• Never risk more than 6% of total account at any one time
• With 2% risk per trade, this means a maximum of 3 open positions
• Reduce this during high-volatility environments
• Close your weakest position before adding a new one

Diversification Rules

• No more than 40% of risk in a single sector (energy, metals, agriculture)
• Include both long and short positions when possible
• Mix timeframes (some short-term, some longer-term)
• Avoid concentration in a single commodity

Key Takeaways

1. Commodity leverage demands smaller position sizes than other markets
2. Gap risk and limit moves require conservative overnight exposure
3. Size positions based on commodity-specific volatility (ATR)
4. Account for correlations between commodity positions
5. Portfolio-level risk limits prevent catastrophic drawdowns
