Methodology

A structured approach to classifying portfolio holdings by role

Classification Hierarchy

Every holding is classified through three levels of specificity:

Level 1: Asset Class
Fixed Income or Equity
Level 2: Role
The intent or purpose this holding serves
Level 3: Asset Detail
Granular categorization within a role

Level 1: Asset Class

The first split is binary: Fixed Income or Equity. This is the only identity-based classification in the system.

Fixed Income includes bonds, CDs, money market funds, preferred stocks and other instruments where the primary return is interest or fixed distributions, not price appreciation.

Equity includes common stocks, stock ETFs and funds where the primary return is capital appreciation and/or dividends from corporate earnings.

Edge cases (convertible bonds, preferred stocks, REITs) are classified by their dominant behavior in your portfolio. If a preferred stock is held for its fixed distribution and stable price, it's Fixed Income. If it's held for price appreciation, it's Equity. Intent determines the classification.

Level 2: Role

Role is the heart of the methodology. It answers: "Why do I own this holding?"

There are nine defined roles: five for Fixed Income, four for Equity. Every holding is assigned to exactly one role. If a holding could fit multiple roles, you choose the primary intent—the main reason it's in your portfolio.

Roles are:

  • Fixed Income: Liquidity Reserve, Capital Preservation, Core Income, Broad Exposure, Enhanced Income
  • Equity: Core Equity, Defensive/Dividend, Growth Equity, Thematic/Opportunistic

These roles are fixed and complete. You don't create new ones. If a holding doesn't fit, you're either misunderstanding the role definitions or you need to reconsider why you own the holding.

Level 3: Asset Detail

Asset Detail provides additional granularity within a role. The detail adds a layer to the asset for analysis and do NOT change/impact the role assignment.

Examples:

  • Within Core Income, you could tag holdings as Cash, Muni (investment-grade) or Core Bond based on risk and duration.
  • Within Core Equity, you could use Growth, Value, Income to track ETF/fund/asset goal or definition.
  • Within Thematic/Opportunistic, you would use sector keywords like Technology, Healthcare, Energy.

Subtypes are descriptive, not prescriptive. They help you see patterns within a role but don't replace the role as the primary classification.

Core Principle: One Holding, One Role

Every holding is assigned to exactly one role.

A holding cannot serve multiple roles simultaneously. If you're tempted to split a holding between "Core Income" and "Broad Exposure," you need to decide which intent is primary.

Why This Matters

  • Clarity: When each holding has one clear purpose, decision-making becomes straightforward. You know what to rebalance, what to trim, what to add.
  • No double-counting: If you allow a holding to count toward multiple roles, your role-based totals will be inflated and misleading.
  • Forces intentionality: Choosing one role forces you to articulate why you own the holding. If you can't decide, you may not need it.

Handling Ambiguity

Some holdings genuinely span multiple intents. A total bond market fund could be "Core Income" (stable income) or "Broad Exposure" (full bond market representation). Both are valid. You choose based on your intent:

  • If you own it because you want broad bond market coverage and don't care much about the income, it's Broad Exposure.
  • If you own it because you want reliable income from a diversified bond allocation, it's Core Income.

There's no "right" answer independent of your intent. The methodology is a tool for organizing your portfolio, not a universal classification system.

Changing Roles

A holding's role can change over time. If you initially bought a stock for growth but now hold it primarily for dividends, you can reclassify it from Growth Equity to Defensive/Dividend. The ticker doesn't change; your intent does.

This flexibility is intentional. Role reflects current purpose, not original purchase rationale.

Roles Overview

The nine roles are organized into two groups: Fixed Income (5 roles) and Equity (4 roles). Each role has a distinct intent and typical characteristics.

This overview provides a high-level summary. Detailed definitions, examples and edge cases are covered in the following sections.

Fixed Income Roles

Role Intent Typical Holdings
Liquidity Reserve Immediate access to cash without principal risk Savings accounts, money market funds, short-term CDs
Capital Preservation Protect principal with minimal volatility Short-term bond funds, stable value funds, ultra-short duration
Core Income Generate reliable income with moderate stability Investment-grade bond funds, intermediate-term bonds
Broad Exposure Capture the full bond market without specific bets Total bond market index funds, aggregate bond ETFs
Enhanced Income Higher yield in exchange for more risk High-yield bonds, emerging market debt, long-duration bonds

Equity Roles

Role Intent Typical Holdings
Core Equity Broad market exposure for long-term growth Total market index funds, S&P 500, broad international
Defensive/Dividend Stable income with downside protection Dividend aristocrats, low-volatility equity, utilities, REITs
Growth Equity Capital appreciation over income Growth funds, small/mid-cap, technology-heavy indices
Thematic/Opportunistic Concentrated conviction plays on sectors or themes Individual stocks, sector ETFs, thematic funds

Role Selection Logic

To assign a holding to a role:

  1. Identify the primary intent: Why did you buy this? What problem does it solve? What outcome do you want?
  2. Match to a role definition: Which role's intent best describes your reason for holding this position?
  3. Confirm with characteristics: Does the holding's behavior (yield, volatility, duration, sector) align with the role's typical characteristics?
  4. Accept imperfect fits: If a holding straddles two roles, choose the dominant intent. There's no "both."

Intent drives classification. Characteristics confirm it. When in doubt, ask: "If I could only assign this to one bucket, which bucket's purpose does it serve most clearly?"

Fixed Income Roles

Five roles that organize fixed income holdings by intent

Fixed income holdings serve different purposes across the risk/return spectrum: liquidity, stability, income generation and market exposure. The five roles reflect this range of intents.

Remember: a holding's role is determined by why you own it, not just by what it is. The same bond fund could serve different roles in different portfolios depending on the investor's intent.

Liquidity Reserve

Immediate access to cash without principal risk

Intent

Liquidity Reserve holdings exist to provide instant or near-instant access to cash for emergencies, planned expenses or opportunistic deployment. Principal preservation and liquidity are absolute priorities. Yield is secondary.

Characteristics

  • Zero or minimal principal risk: Holdings should not lose value under normal market conditions.
  • High liquidity: Funds available within 1-3 business days at most.
  • Low or no volatility: Value remains stable regardless of interest rate changes.
  • Low yield: Returns are typically below inflation. That's the cost of liquidity and safety.

Typical Holdings

  • Savings accounts (FDIC-insured)
  • Money market funds
  • Treasury bills (short-term, e.g., 4-week to 3-month)
  • Short-term CDs (if early withdrawal penalties are acceptable or non-existent)

Examples

  • VUSXX (Vanguard Treasury Money Market Fund)
  • SPAXX (Fidelity Government Money Market Fund)
  • SGOV (iShares 0-3 Month Treasury Bond ETF)
  • High-yield savings accounts at online banks

Account Placement

Preferred: Taxable

Liquidity needs are unpredictable. Holding cash in taxable accounts avoids early withdrawal penalties, RMD complications and the opportunity cost of locking safe assets in tax-advantaged space. The tax drag on low yields is minimal compared to the value of accessible liquidity.

Common Mistakes

  • Chasing yield: Stretching into bond funds or CDs with longer durations defeats the purpose. If you need liquidity, accept the lower yield.
  • Confusing with Capital Preservation: Capital Preservation can have some volatility and slower access. Liquidity Reserve cannot.
  • Over-allocating: Liquidity Reserve is expensive (opportunity cost of low returns). Hold enough to cover true emergencies and near-term needs, not speculative cash hoarding.

Role Boundaries

If a holding has principal risk or takes more than a few days to access, it's not Liquidity Reserve. Move it to Capital Preservation or another role.

Capital Preservation

Protect principal with minimal volatility

Intent

Capital Preservation holdings prioritize protecting the nominal value of your investment. They can tolerate minor fluctuations but should not experience meaningful drawdowns. Modest income is acceptable, but the primary goal is stability, not yield.

Characteristics

  • Low volatility: Value should remain relatively stable even when interest rates change.
  • Short duration: Typically 0-3 years, reducing interest rate sensitivity.
  • High credit quality: Investment-grade or better to minimize default risk.
  • Modest yield: Returns are low but higher than Liquidity Reserve because you're giving up some liquidity.

Typical Holdings

  • Short-term bond funds (1-3 year duration)
  • Stable value funds (in 401k plans)
  • Ultra-short bond ETFs
  • Individual bonds held to maturity (short-term, investment-grade)

Examples

  • VFSUX (Vanguard Short-Term Investment-Grade Fund)
  • BSV (Vanguard Short-Term Bond ETF)
  • NEAR (iShares Short Maturity Bond ETF)
  • JPST (JPMorgan Ultra-Short Income ETF)

Account Placement

Preferred: Taxable or Tax-Deferred

Capital Preservation can work in either account type. In taxable accounts, short-term bond funds are reasonably tax-efficient. In tax-deferred accounts, they avoid the tax drag on modest income. Choose based on where you need stability: near-term withdrawals → taxable; long-term ballast in a retirement account → tax-deferred.

Common Mistakes

  • Reaching for yield: Adding longer duration or lower credit quality undermines the stability goal.
  • Confusing with Core Income: Core Income accepts more volatility in exchange for higher income. Capital Preservation does not.
  • Ignoring inflation: Capital Preservation protects nominal value, not purchasing power. Real returns may be negative after inflation and taxes.

Role Boundaries

If a holding can drop 5%+ in a rate shock, it's not Capital Preservation. If it offers no yield advantage over money market funds, it's Liquidity Reserve. If income generation is the primary goal, it's Core Income.

Core Income

Generate reliable income with moderate stability

Intent

Core Income holdings are the foundation of fixed income allocation for investors seeking regular income. They balance yield, credit quality and interest rate sensitivity. The goal is dependable income without excessive risk.

Characteristics

  • Investment-grade credit: Primarily AAA to BBB-rated bonds to minimize default risk.
  • Moderate duration: Typically 3-7 years. Enough sensitivity to benefit from rate declines, not so much that rate increases cause severe drawdowns.
  • Consistent distributions: Income is the primary return driver, not capital appreciation.
  • Diversified: Broad exposure across issuers, sectors and maturities to reduce idiosyncratic risk.

Typical Holdings

  • Intermediate-term bond funds (aggregate, corporate, government)
  • Core bond index funds (e.g., Bloomberg U.S. Aggregate Bond Index)
  • Laddered portfolios of investment-grade bonds
  • Municipal bond funds (in taxable accounts for tax-exempt income)

Examples

  • BND (Vanguard Total Bond Market ETF)
  • AGG (iShares Core U.S. Aggregate Bond ETF)
  • VCIT (Vanguard Intermediate-Term Corporate Bond ETF)
  • MUB (iShares National Muni Bond ETF) — if held for tax-exempt income

Account Placement

Preferred: Tax-Deferred

Core Income generates regular taxable interest. Tax-deferred accounts (Traditional IRA, 401k) shelter this income from annual taxation. Exception: municipal bond funds, which are tax-exempt and should be held in taxable accounts.

Common Mistakes

  • Chasing yield with high-yield bonds: High-yield (junk) bonds are Enhanced Income, not Core Income. They carry materially higher default risk.
  • Over-concentrating in one sector: Core Income should be diversified. A portfolio of only Treasury bonds or only corporate bonds is a sector bet, not a core allocation.
  • Ignoring duration risk: Longer duration = higher sensitivity to interest rate changes. Understand the trade-off between yield and volatility.

Role Boundaries

If a holding is primarily treasuries or government bonds with no credit risk, consider Broad Exposure if the intent is market representation rather than income. If credit quality drops below investment grade, it's Enhanced Income.

Broad Exposure

Capture the full bond market without specific bets

Intent

Broad Exposure holdings provide diversified representation of the entire bond market. The goal is not to outperform or generate maximum income, but to capture the bond market's aggregate behavior as a portfolio ballast and diversifier.

Characteristics

  • Market-weight allocation: Holdings reflect the bond market's natural composition across credit quality, duration and issuer type.
  • No active bets: No overweights or underweights based on predictions about rates, credit spreads or sectors.
  • Low cost: Index-based, minimal turnover, low expense ratios.
  • Diversification across sectors: Includes government, corporate, mortgage-backed securities in proportion to the broader market.

Typical Holdings

  • Total bond market index funds
  • Aggregate bond index ETFs
  • Funds tracking the Bloomberg U.S. Aggregate Bond Index or similar benchmarks

Examples

  • BND (Vanguard Total Bond Market ETF)
  • AGG (iShares Core U.S. Aggregate Bond ETF)
  • FXNAX (Fidelity U.S. Bond Index Fund)

Distinguishing from Core Income

This is the trickiest boundary in the Fixed Income roles. Many funds qualify for both Core Income and Broad Exposure. The distinction is your intent:

  • Broad Exposure: You own it because you want bond market representation—whatever the bond market is doing, you're doing. Income is incidental.
  • Core Income: You own it because you want reliable income. The diversification is a means to that end, not the primary goal.

Same fund, different role, depending on why it's in your portfolio.

Account Placement

Preferred: Tax-Deferred

Broad Exposure funds generate taxable interest distributions. Tax-deferred accounts avoid the annual tax drag.

Common Mistakes

  • Adding sector tilts: If you're overweighting corporate bonds or excluding government bonds, you've moved away from broad market exposure and into an active bet.
  • Confusing with a "do everything" fund: Broad Exposure is about market representation, not maximizing yield or minimizing volatility. It will underperform both in different environments.

Role Boundaries

If a fund excludes major sectors (e.g., only Treasuries, only corporates), it's not Broad Exposure. If you're holding it for income generation rather than market representation, classify it as Core Income.

Enhanced Income

Higher yield in exchange for more risk

Intent

Enhanced Income holdings prioritize yield over stability. They accept higher volatility, credit risk or interest rate sensitivity in pursuit of above-market income. This is the aggressive end of the fixed income spectrum.

Characteristics

  • Higher yield: Distributions meaningfully exceed investment-grade bond yields.
  • Elevated risk: Credit risk (below investment grade), interest rate risk (long duration), or emerging market risk.
  • More volatility: Prices fluctuate more than Core Income or Broad Exposure holdings.
  • Active or strategic bets: Often involves concentrated sector or geography exposure.

Typical Holdings

  • High-yield (junk) bond funds
  • Emerging market debt
  • Long-duration bond funds (20+ year Treasuries for yield, accepting rate risk)
  • Preferred stock funds (if held primarily for income)
  • Leveraged bond ETFs

Examples

  • HYG (iShares iBoxx $ High Yield Corporate Bond ETF)
  • JNK (SPDR Bloomberg High Yield Bond ETF)
  • EMB (iShares JP Morgan USD Emerging Markets Bond ETF)
  • TLT (iShares 20+ Year Treasury Bond ETF) — if held for income despite duration risk
  • PFF (iShares Preferred and Income Securities ETF)

Account Placement

Preferred: Tax-Deferred

Enhanced Income generates high taxable distributions. Tax-deferred accounts shelter this income. Additionally, the volatility of these holdings makes them poor candidates for taxable accounts where tax-loss harvesting might be needed frequently.

Common Mistakes

  • Treating as safe income: Enhanced Income is not safe. Defaults, credit spread widening and interest rate shocks can cause significant losses.
  • Over-allocating: High yield is tempting, but concentration in Enhanced Income undermines the stability that fixed income is supposed to provide.
  • Confusing with Core Income: If it's below investment grade or has extreme duration, it's Enhanced Income, not Core.

Role Boundaries

If a holding is investment-grade with moderate duration, it's Core Income or Broad Exposure, not Enhanced Income. The line is credit quality and risk level: if you're accepting materially higher risk for higher yield, it's Enhanced Income.

Equity Roles

Four roles that organize equity holdings by intent

Equity holdings serve different purposes: broad market participation, income with stability, aggressive growth or concentrated thematic bets. The four roles reflect these intents.

As with fixed income, role assignment depends on why you own it, not just the fund's characteristics. Context matters.

Core Equity

Broad market exposure for long-term growth

Intent

Core Equity holdings provide diversified exposure to the stock market. The goal is to capture long-term equity returns without making specific bets on sectors, styles or geographies. This is the foundation of most equity allocations.

Characteristics

  • Market-weight or cap-weight: Holdings reflect the natural market composition.
  • Broad diversification: Hundreds or thousands of stocks across sectors and industries.
  • Passive or index-based: Minimal active management, low turnover, low fees.
  • Long-term focus: Held for years or decades, not traded tactically.

Typical Holdings

  • Total stock market index funds
  • S&P 500 index funds
  • Broad international equity funds (developed markets)
  • Global equity index funds

Examples

  • VTI (Vanguard Total Stock Market ETF)
  • VOO (Vanguard S&P 500 ETF)
  • VXUS (Vanguard Total International Stock ETF)
  • ACWI (iShares MSCI ACWI ETF)
  • SCHB (Schwab U.S. Broad Market ETF)

Account Placement

Preferred: Taxable or Tax-Deferred

Core Equity works well in both account types. In taxable accounts, broad index funds are tax-efficient (low turnover, long-term capital gains, qualified dividends). In tax-deferred accounts, they grow without annual tax drag. Allocation depends on your overall account mix and withdrawal timeline.

Common Mistakes

  • Overlapping funds: Owning both VTI and VOO is redundant. They're 80%+ the same holdings. Pick one.
  • Confusing with Thematic/Opportunistic: If you're making a bet on a specific sector or trend, it's not Core Equity.
  • Adding factor tilts and calling it "core": A small-cap value fund is not Core Equity. It's a deliberate deviation from market weights.

Role Boundaries

If a fund focuses on a specific sector, market cap, style (growth/value) or geography (e.g., only emerging markets), it's not Core Equity. If it's held primarily for dividends, it's Defensive/Dividend. If it's growth-focused with low or no dividends, it's Growth Equity.

Defensive/Dividend

Stable income with downside protection

Intent

Defensive/Dividend holdings prioritize income and lower volatility within the equity allocation. They're the equity equivalent of "ballast": less upside in bull markets, less downside in bear markets and consistent distributions regardless of market conditions.

Characteristics

  • High dividend yield: Above-average distributions compared to broad market indices.
  • Lower volatility: Less price fluctuation than growth stocks or broad equity indices.
  • Established companies: Mature, profitable firms with long track records of dividend payments.
  • Sector concentration: Often overweight utilities, consumer staples, REITs and other defensive sectors.

Typical Holdings

  • Dividend aristocrat or dividend growth ETFs
  • High-dividend equity funds
  • Low-volatility equity ETFs
  • REIT funds (if held for income)
  • Utility sector funds
  • Individual dividend-paying stocks (blue chips, utilities)

Examples

  • SCHD (Schwab U.S. Dividend Equity ETF)
  • VIG (Vanguard Dividend Appreciation ETF)
  • SPHD (Invesco S&P 500 High Dividend Low Volatility ETF)
  • USMV (iShares MSCI USA Min Vol Factor ETF)
  • VNQ (Vanguard Real Estate ETF)

Account Placement

Preferred: Taxable

Qualified dividends receive favorable tax treatment in taxable accounts (0%, 15%, or 20% depending on income vs. ordinary income rates). This makes dividend-focused equity holdings more tax-efficient in taxable accounts than in tax-deferred accounts where they'd eventually be taxed as ordinary income upon withdrawal.

Exception: REITs are generally not qualified dividends and are better in tax-deferred accounts.

Common Mistakes

  • Chasing yield without regard to sustainability: High yields can signal distress or unsustainable payout ratios. Check dividend safety.
  • Confusing with Core Equity: Dividend funds are a subset of the market, not the whole market. They're a deliberate tilt toward income and stability.
  • Ignoring total return: Dividends are only part of the picture. A high-dividend fund that consistently underperforms on price may not be serving its purpose.

Role Boundaries

If a holding doesn't prioritize dividends or lower volatility, it's not Defensive/Dividend. If it's a broad market fund that happens to pay dividends, classify it as Core Equity. If it's held for growth despite the dividends, classify it as Growth Equity.

Growth Equity

Capital appreciation over income

Intent

Growth Equity holdings prioritize price appreciation. Dividends are minimal or nonexistent. The focus is on companies or sectors expected to grow faster than the broader market. Volatility is accepted as the price of potential outperformance.

Characteristics

  • Low or no dividends: Companies reinvest earnings into growth rather than distributing them.
  • Higher volatility: More price fluctuation than Core Equity or Defensive/Dividend holdings.
  • Growth-oriented sectors: Technology, consumer discretionary, small-cap, emerging markets.
  • Long-term focus: Gains come from compounding price appreciation, not income.

Typical Holdings

  • Growth stock funds (large-cap, mid-cap, small-cap)
  • Technology-heavy indices (e.g., Nasdaq-100)
  • Small-cap or mid-cap growth funds
  • Emerging market equity funds (if held for growth, not diversification)
  • Innovation or disruptive technology funds

Examples

  • QQQ (Invesco QQQ Trust - Nasdaq-100)
  • VUG (Vanguard Growth ETF)
  • VOOG (Vanguard S&P 500 Growth ETF)
  • VB (Vanguard Small-Cap ETF)

Account Placement

Preferred: Tax-Deferred or Tax-Free (Roth)

Growth holdings benefit most from long-term compounding without tax drag. Roth accounts are ideal: grow tax-free, withdraw tax-free. Traditional IRAs and 401(k)s also work well since you're not harvesting income annually. In taxable accounts, growth funds can trigger capital gains distributions and short-term gains if actively managed.

Common Mistakes

  • Over-concentrating in one sector: A portfolio of only tech or only small-cap growth is high-risk. Balance with Core Equity.
  • Confusing with Thematic/Opportunistic: Growth Equity is still diversified within its category. A single stock or narrow sector bet is Thematic/Opportunistic.
  • Ignoring valuation: Growth stocks can become overvalued. Understand that high growth expectations are priced in.

Role Boundaries

If a holding is broadly diversified across the market, it's Core Equity, not Growth. If it focuses on dividends, it's Defensive/Dividend. If it's a single stock or hyper-concentrated sector bet, it's Thematic/Opportunistic.

Thematic/Opportunistic

Concentrated conviction plays on sectors or themes

Intent

Thematic/Opportunistic holdings represent your highest-conviction ideas: individual stocks, narrow sector bets or thematic trends you believe will outperform. These are deliberate deviations from market-weight allocations. Risk and volatility are highest here.

Characteristics

  • Concentrated exposure: Single stocks, narrow sectors or specific investment themes.
  • High conviction: You're making a bet that this position will outperform the market.
  • Higher risk: Idiosyncratic risk (company-specific), sector risk or trend risk if the theme doesn't play out.
  • Active management or selection: You chose this position based on research, conviction or a specific thesis.

Typical Holdings

  • Individual stocks
  • Sector ETFs (technology, healthcare, energy, financials, etc.)
  • Thematic ETFs (clean energy, AI, genomics, cybersecurity)
  • Country-specific funds (e.g., China, India) if held as a tactical bet
  • Leveraged or inverse ETFs (if you're making directional bets)

Examples

  • Individual stocks: AAPL, MSFT, TSLA, NVDA
  • XLK (Technology Select Sector SPDR Fund)
  • ICLN (iShares Global Clean Energy ETF)
  • HACK (ETFMG Prime Cyber Security ETF)

Account Placement

Preferred: Tax-Deferred or Tax-Free (Roth)

Thematic/Opportunistic holdings can be volatile and may trigger frequent trades, capital gains or losses. Tax-advantaged accounts avoid the tax complexity. Roth is ideal if you expect massive gains (let winners run tax-free). Traditional IRA/401(k) works if you're uncertain and want flexibility to rebalance without tax consequences.

Common Mistakes

  • Over-allocating: Thematic bets should be a small percentage of your equity allocation. Concentration risk can devastate a portfolio.
  • Confusing with Core Equity: A sector ETF is not diversified. It's a bet on one part of the market.
  • Chasing trends: Thematic funds often launch after a trend is already priced in. Be wary of performance-chasing.
  • Ignoring correlation: If all your thematic bets are in the same sector (e.g., tech stocks + tech ETF + AI fund), you're massively concentrated even if you own "multiple holdings."

Role Boundaries

If a holding is broadly diversified, it's Core Equity or Growth Equity, not Thematic/Opportunistic. If you're holding it passively without a specific thesis, reconsider whether it belongs here. Thematic/Opportunistic should be active, intentional and high-conviction.
