Liquidity Screen

A liquidity screen applies declared market-activity and tradability criteria to determine index or universe eligibility.

Also known asliquidity eligibility screen

Definitions

In plain terms

It may require minimum traded value, trading frequency, history, spread, or other measures before a security can enter or remain.

Technical

The screen defines metrics, sources, windows, currencies, thresholds and inclusivity, new-listing treatment, missing days, buffers, effective dates, and exceptions.

Scope

Passing a historical screen does not guarantee future capacity or executable liquidity.

Examples

  • A governed methodology records liquidity screen with its source, cutoff, units, parameters, and effective version.

Common misconceptions

  • Liquidity Screen does not have one universal implementation without the declared methodology, data basis, and constraints.
