Lit Market Fragmentation
Lit Market Fragmentation — Split liquidity across exchanges raising routing complexity.
Definition
Lit Market Fragmentation refers to split liquidity across exchanges raising routing complexity. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
Price formation at the venue layer decides whether a signal survives implementation. When split liquidity across exchanges raising routing complexity shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what lit market fragmentation is saying. If split liquidity across exchanges raising routing complexity moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
