Lit Market Percentage

Lit market percentage reflects market fragmentation and the degree to which price discovery occurs on regulated venues with full pre- and post-trade transparency. A higher percentage indicates greater reliance on lit markets and reduced information asymmetry. In insider-trading detection contexts, elevated lit market percentage can signal reduced opportunities for concealment via dark-pool routing, making insider trades more visible to surveillance systems and forensic analysts.

For quant scoring platforms evaluating suspicious transaction patterns, lit market percentage serves as a contextual variable to normalize detected anomalies. When a PDMR or beneficial owner executes large blocks on undisplayed venues, a low lit market percentage may amplify conviction in coordinated concealment behavior. Conversely, securities with high lit market percentages constrain the feasibility of stealth accumulation, reducing false-positive alerts driven by normal liquidity-seeking behavior.
