Why These Levels

The reasoning behind each dimension requirement.

Formality: L4

Formality L4 (rebalancing rules + tax rules formalized), Structure L4 (tax-aware portfolio ontology) . F:2, S:2 → BLOCKED. Rebalancing logic tribal, tax rules not executable.

Capture: L3

Formality L4 (rebalancing rules + tax rules formalized), Structure L4 (tax-aware portfolio ontology) . F:2, S:2 → BLOCKED. Rebalancing logic tribal, tax rules not executable.

Structure: L4

Formality L4 (rebalancing rules + tax rules formalized), Structure L4 (tax-aware portfolio ontology) . F:2, S:2 → BLOCKED. Rebalancing logic tribal, tax rules not executable.

Accessibility: L3

Formality L4 (rebalancing rules + tax rules formalized), Structure L4 (tax-aware portfolio ontology) . F:2, S:2 → BLOCKED. Rebalancing logic tribal, tax rules not executable.

Maintenance: L3

Formality L4 (rebalancing rules + tax rules formalized), Structure L4 (tax-aware portfolio ontology) . F:2, S:2 → BLOCKED. Rebalancing logic tribal, tax rules not executable.

Integration: L3

Formality L4 (rebalancing rules + tax rules formalized), Structure L4 (tax-aware portfolio ontology) . F:2, S:2 → BLOCKED. Rebalancing logic tribal, tax rules not executable.

What Must Be In Place

Concrete structural preconditions — what must exist before this capability operates reliably.

Primary Structural Lever

How explicitly business rules and processes are documented

The structural lever that most constrains deployment of this capability.

How explicitly business rules and processes are documented

  • Formal rebalancing policy documents encoding drift thresholds, band tolerances, and wash-sale rules as structured, queryable constraint records

Whether operational knowledge is systematically recorded

  • Systematic capture of tax lot data including cost basis, acquisition dates, and holding period classifications linked to current portfolio positions

How data is organized into queryable, relational formats

  • Consistent schema for target allocation records, tax lot hierarchies, and client tax profile parameters enabling cross-lot optimization queries

Whether systems expose data through programmatic interfaces

  • Queryable access to tax lot records, client constraint parameters, and compliance rule sets across portfolio management and tax accounting systems

How frequently and reliably information is kept current

  • Scheduled drift monitoring comparing current allocations against target weights with automated alerts when band tolerances are exceeded

Whether systems share data bidirectionally

  • Middleware integration connecting rebalancing engine outputs to pre-trade compliance checks, order management, and post-trade tax lot update processes

Common Misdiagnosis

Teams focus on optimization algorithm sophistication while wash-sale restriction logic and client-specific constraint definitions remain in unstructured mandate documents, causing the system to generate trade lists that compliance must manually review and reject at high rates.

Recommended Sequence

Encode rebalancing policies and wash-sale constraints into structured records (F) before building the tax lot schema (S); optimization logic cannot enforce client-specific constraints it cannot systematically read and validate.
