Methodology
Cross-venue dispersion
How the same ticker is compared without ranking a winner.
Updated 2026-09-27
Dispersion is the range of marks, basis and funding across venues that list the same underlying in this book. Names with a single listing are left off the table.
The widest range is not a recommended pair. Different multipliers, collateral, funding intervals and unpublished corporate-action clauses mean the two contracts are not the same risk. Withheld confidence scores are counted, not filled with zero.
