Playbook: Designing Liquidity Layers for Concentrated Holdings
When a portfolio has concentrated sector exposure, execution risk during stress events becomes the dominant driver of realized loss. This playbook outlines a three-tier liquidity layering approach: strategic core, rotational sleeve, and tactical buffer. The strategic core preserves long-term exposure but is sized with scenario-weighted stress limits. The rotational sleeve uses AI-derived rebalancing windows and market impact estimates to moderate trading schedules. The tactical buffer holds highly liquid instruments and cash-like exposures to fund opportunistic rebalancing without forced liquidations. Each layer includes explicit trigger thresholds linked to observable signals such as depth anomalies, bid-ask widening, and cross-asset dispersion. Human stewards receive annotated triggers with confidence scores and documented escalation procedures so that model-driven actions can be paused or adjusted in light of qualitative developments. The aim is to reduce execution volatility while preserving the ability to act when structural repricing creates opportunity.
