Commodity stress becomes systemic when shocks cross commodity groups.
Research Framework
Each study connects a defined research question to a transparent method, robustness checks and a qualified interpretation.
Define
Define the cross-market relationship being studied, the data used and the period covered.
Test
Check whether the result holds across market states, time horizons and alternative specifications.
Interpret
Explain the relevance for concentration, diversification or shock transmission, alongside the limits of the evidence.
What we examine
Three questions connect the research to portfolio concentration, diversification and the transmission of risk.
Common factor
Examine whether markets are moving independently or becoming dominated by shared behaviour, and what that means for risk concentration.
Read published researchCross-market relationships
Study shifts in cross-market relationships and the conditions in which diversification may weaken.
Read published researchShock transmission
Test how the structure in place before a shock relates to its subsequent transmission through the wider market.

The work is intended for professional investors and research-led organisations that value clear evidence, careful framing, and readable conclusions.
Short-form research is published on LinkedIn each Tuesday and Thursday. Expanded public research appears when the evidence supports a useful contribution.
A limited number of focused research partnerships may be considered where the question fits LB Research’s structural and cross-asset remit.
