Core Competencies

Investment Theory

• Modern Portfolio Theory: Efficient frontier, mean-variance optimization
• Factor Investing: Fama-French factors, size/value/momentum premiums
• Sequence of Returns Risk: Critical for retirement planning
• Asset Allocation: Risk/return optimization

For mathematical implementations, see /references/investment-theory.md

Tax Optimization

• Asset Location: What to hold where (taxable vs. tax-deferred vs. Roth)
• Tax-Loss Harvesting: Systematic loss capture with wash sale avoidance
• Roth Conversion Ladder: Early retirement access strategy
• Tax Bracket Management: Filling brackets strategically

For strategies and code, see /references/tax-optimization.md

Withdrawal Mathematics

• Trinity Study: Original and updated research
• Dynamic Withdrawal Strategies: Guyton-Klinger, VPW, CAPE-based
• Monte Carlo Simulation: Retirement success probability
• FIRE Calculations: FI number, Coast FIRE, Barista FIRE

For simulations and calculations, see /references/withdrawal-math.md

Quick Reference

Safe Withdrawal Rates by CAPE

Factor Premiums (Historical)

FIRE Numbers

• Standard FIRE: Annual Expenses × 25 (4% SWR)
• Conservative FIRE: Annual Expenses × 33 (3% SWR)
• Coast FIRE: FI_number / (1 + growth_rate)^years_to_retirement

Anti-Patterns

Optimizing for Taxes Over Returns

What it looks like: Making investment decisions purely for tax benefits.
Why it's wrong: Tax tail wagging the investment dog; net returns matter.
Instead: Optimize for after-tax returns, not just tax efficiency.

Ignoring Sequence of Returns Risk

What it looks like: Using average returns to plan retirement withdrawals.
Why it's wrong: Order of returns matters enormously with withdrawals.
Instead: Model sequence risk, use dynamic withdrawal strategies.

Complexity for Complexity's Sake

What it looks like: 15 different accounts, complex factor tilts, constant rebalancing.
Why it's wrong: Complexity costs time, attention, and often money.
Instead: Simple portfolios (3-fund) work for most people.

Anchoring to 4% Rule Without Context

What it looks like: "The Trinity Study says 4% is safe, so I'm done."
Why it's wrong: Original study used 1926-1995 data; current valuations matter.
Instead: Adjust SWR based on CAPE, time horizon, and flexibility.
