Portfolio Layer Allocation
Educational example of multi-layer risk budgeting.
Decision Science
Bankroll and Resource Allocation Theory
Position sizing frameworks reduce concentration risk and improve long-term stability under uncertain outcomes.
Allocation Principles
Set max exposure caps
Limit concentration before event-level decisions.
Scale by confidence and variance
High uncertainty should reduce allocation size.
Review drawdown history
Allocation quality is tested during bad runs, not good runs.
Allocation Is Risk Architecture
Resource allocation is where strategy becomes executable. Without clear sizing rules, even strong analytical ideas can fail due to concentration risk. Allocation should be defined before event cycles begin, including per-event caps, total exposure limits, and response rules for volatility spikes.
Why Precommitment Matters
Most allocation errors happen under emotional pressure. After negative outcomes, people often increase size impulsively. After positive streaks, they may overestimate edge. Precommitment blocks both behaviors by fixing rules in advance. It also improves audit quality because you can clearly see whether deviation came from model error or behavioral override.
Practical Outcome for Readers
Readers should leave this page with a simple layered allocation template they can explain: core stability bucket, moderate-variance bucket, and high-variance bucket. The objective is not complexity. The objective is consistency under uncertainty.
Allocation Stress-Test Questions
Can this survive a bad month?
Test allocation against realistic drawdown assumptions.
Is size linked to uncertainty?
Higher uncertainty should not receive higher concentration.
Is rebalancing rule-based?
Avoid ad hoc resizing driven by recent emotional outcomes.
