Liquidity Metrics Quant Interview Guide
Liquidity metrics quant interview guide covering spread, depth, average volume, volume curves, turnover, resiliency, capacity, and examples.
Candidates measuring spread, depth, volume, turnover, and execution capacity.
Liquidity is multidimensional
Liquidity includes spread, depth, volume, turnover, resiliency, market impact, venue access, and ability to trade size under stress.
Average volume is only a start
ADV can indicate capacity, but intraday volume curve, block liquidity, spread, volatility, and participation rate also matter.
Concrete example
A stock with high daily volume can still be costly to trade if quoted spread is wide or volume concentrates in short windows.
Resiliency matters after trades
A liquid market replenishes depth after shocks. A market that looks deep but disappears under pressure is riskier than it appears.
Common mistakes
Candidates often quote one liquidity number. Execution interviews reward combining spread, depth, volume, impact, and stress behavior.
