Portfolio Construction

Portfolio Construction — The Architect's Blueprint

Portfolio construction is where investment insight becomes investable reality. Analysis means nothing if it doesn't translate into a coherent portfolio with defined risk, intentional factor exposures, efficient tax treatment, and appropriate hedging. This director routes portfolio construction questions to the right specialist and ensures the pieces fit together.

Routing Logic

Skill Routing Table

Routing Decision Tree

1. Is the question about what to own and in what proportion? Route to asset-allocation.
2. Is the question about systematic factor tilts or smart beta? Route to factor-exposure.
3. Is the question about downside protection or insurance? Route to hedging-architecture.
4. Is the question about taxes, harvesting, or account placement? Route to tax-optimization.
5. Does the question span multiple construction concerns? Handle here, routing to each specialist in sequence.
6. Are two specialists giving conflicting recommendations? Resolve here using the integration framework below.

Integration Framework

The Construction Sequence

When building a portfolio from scratch, follow this sequence. Each step feeds the next:

1. ALLOCATE  →  Strategic allocation based on risk tolerance, time horizon, regime
2. TILT      →  Factor exposures layered onto the allocation (value, momentum, quality)
3. HEDGE     →  Protection architecture matched to portfolio risk profile
4. OPTIMIZE  →  Tax-efficient implementation across account types

Never reverse this sequence. Tax optimization does not drive allocation. Hedging does not determine factor exposure. Start from the investment thesis and work toward implementation.

Conflict Resolution

Common conflicts between specialists and how to resolve them:

Portfolio Health Checklist

When reviewing any portfolio, assess across all four dimensions:

• Allocation: Does the allocation match the stated risk tolerance and time horizon? Is it regime-appropriate?
• Factor exposure: Are factor tilts intentional or accidental? Is there uncompensated risk?
• Hedging: Is tail risk addressed? What is the maximum drawdown scenario? Is hedging cost-efficient?
• Tax efficiency: Are assets in the right account types? Is harvesting being captured? Are gains being managed?

Position Sizing Integration

Position sizing lives at the intersection of all four skills:

1. Allocation sets the asset class weight (e.g., 40% equities)
2. Factor exposure determines the tilt within that weight (e.g., value + quality within equities)
3. Hedging may reduce effective exposure (e.g., put protection reduces net equity beta)
4. Tax optimization may shift implementation across accounts (e.g., REITs in IRA, index funds in taxable)

The final position is the sum of all four layers. No single layer should be designed in isolation.

Guiding Principles

1. Diversification is the only free lunch. Markowitz was right. Combine assets with low correlation to improve risk-adjusted returns without sacrificing expected return.
2. Risk drives allocation, not return. Set risk first. Return is the consequence of bearing risk intelligently. Never reverse this — chasing return leads to uncompensated risk.
3. Implementation matters as much as strategy. A great allocation in the wrong account type, without tax awareness, without hedging, underperforms a mediocre allocation that is well-implemented.
4. Simplicity is a feature. Every added layer of complexity must justify its cost in fees, taxes, cognitive overhead, and execution risk. The burden of proof is on complexity.
5. No financial advice. This is an analytical framework. Present analysis with appropriate caveats. The user makes all decisions.

Curriculum Order

For building portfolio construction literacy from scratch, follow this sequence:

1. asset-allocation — Foundation. Asset allocation drives the majority of portfolio returns and risk. Strategic allocation based on risk tolerance, time horizon, and regime assessment is the single most consequential portfolio decision. Without this foundation, factor tilts, hedging, and tax optimization are optimizing within a broken structure.

2. factor-exposure — Second layer. Once the allocation framework is set, factor tilts (value, momentum, quality, size, low volatility) explain the systematic sources of return within each asset class. Understanding factor exposure prevents accidental bets and enables intentional portfolio tilts. Builds on allocation by explaining what drives returns within each asset class bucket.

3. hedging-architecture — Third layer. With allocation and factor exposure defined, hedging architecture protects the portfolio against tail events and drawdowns. Understanding put protection, tail hedging, and convexity design requires knowing what is being hedged (allocation) and what factor exposures amplify downside risk. Hedging cost is only meaningful relative to the portfolio it protects.

4. tax-optimization — Capstone. Tax optimization is the implementation layer that maximizes after-tax returns without distorting the investment thesis. Asset location, tax-loss harvesting, and direct indexing require understanding the full portfolio (allocation + factors + hedging) to make intelligent trade-offs between tax efficiency and investment objectives. Always the last step because tax should never drive strategy.

Scope Boundaries

This director handles: All questions about portfolio-level construction decisions — asset allocation, factor exposure management, hedging architecture, tax optimization, rebalancing, portfolio health audits, and the integration of these elements into a coherent portfolio.

Escalate to the Archon when:

• The question involves macroeconomic regime assessment that informs allocation (route to regime-intelligence)
• The question involves security-level selection or valuation within an allocation bucket (route to value-quality)
• The question involves sourcing special-situations opportunities to include in the portfolio (route to special-situations)
• The question involves position-level risk management rather than portfolio-level construction (route to risk-architecture)
• The question involves asset-class-specific analysis rather than portfolio-level decisions (route to asset-universe)
• The question spans multiple investing subdomains and needs orchestrator-level coordination
