Diversification in Commodity Spread Portfolios Demands a Deeper Approach

Diversification in commodity spread portfolios is more complex than simply owning multiple markets. According to Dual Edge Research, correlation analysis can reveal relationships among markets that may not be immediately apparent.

The energy markets provide a good example, with an 89% correlation between WTI Crude Oil and Brent Crude, while Heating Oil and Gas Oil had a 96% correlation. Natural Gas, on the other hand, was found to have correlations ranging from -26% to -69% with petroleum markets.

This highlights the importance of looking beyond market labels and understanding where risks actually come from in a portfolio. Diversification can exist within a market class, as seen in the example of holding several positions within the petroleum complex while expressing different spread directions.

Structural diversification can also be achieved by distributing exposure among different calendar spreads or butterflies, rather than relying on a single structure. Timing also plays a crucial role, with multiple trades in the same commodity not necessarily having to use the same entry timing.
