Activation
This skill activates when the user runs:
/trade portfolio- Any request to analyze portfolio holdings, allocation, or rebalancing
Input Collection
Step 1: Gather Holdings
Ask the user to provide their holdings in one of these formats:
Format A — Shares:
AAPL 100
MSFT 50
GOOGL 25
VTI 200
BND 150
Format B — Dollar Amounts:
AAPL $15,000
MSFT $20,000
GOOGL $8,000
VTI $30,000
BND $12,000
Format C — Natural Language: "I have 100 shares of Apple, $20K in Microsoft, 50 shares of Google, and about $30K in VTI"
If the user provides a mixed format, normalize everything to shares + current market value using WebSearch for current prices.
Step 2: Gather Optional Context
Ask (but do not require):
- Investment goal (growth, income, preservation, balanced)
- Time horizon (short <1yr, medium 1-5yr, long 5yr+)
- Risk tolerance (conservative, moderate, aggressive)
- Benchmark preference (default: SPY)
- Any positions they cannot sell (tax lots, restricted stock)
Analysis Process
Phase 1: Position Mapping
For each holding, use WebSearch to gather:
- Current price and market value
- Sector classification (GICS)
- Market cap category (mega, large, mid, small, micro)
- Country/region of primary revenue
- Asset class (equity, fixed income, commodity, REIT, crypto)
- Dividend yield and ex-dividend date
Calculate:
- Total portfolio value
- Each position as % of total portfolio
- Position count and average position size
Phase 2: Sector Allocation Analysis
Map all holdings to their GICS sectors:
- Technology
- Healthcare
- Financials
- Consumer Discretionary
- Consumer Staples
- Industrials
- Energy
- Utilities
- Real Estate
- Materials
- Communication Services
Compare to benchmark (SPY) sector weights. Flag:
- Overweight sectors: >5% above benchmark
- Underweight sectors: >5% below benchmark
- Missing sectors: 0% allocation where benchmark has >3%
Phase 3: Geographic Exposure
Classify each holding by revenue source:
- US Domestic: >70% US revenue
- International Developed: Primary revenue from EU, Japan, UK, Australia
- Emerging Markets: Primary revenue from China, India, Brazil, etc.
- Global Diversified: No single region >50%
Calculate total geographic breakdown and compare to global market cap weights.
Phase 4: Correlation Analysis
Use WebSearch to find correlation data between major holdings. Build a simplified correlation matrix:
AAPL MSFT GOOGL VTI BND
AAPL 1.00 0.85 0.78 0.82 -0.15
MSFT 0.85 1.00 0.80 0.80 -0.12
GOOGL 0.78 0.80 1.00 0.79 -0.18
VTI 0.82 0.80 0.79 1.00 -0.20
BND -0.15 -0.12 -0.18 -0.20 1.00
Flag:
- High correlation pairs (>0.80): These do NOT provide diversification
- Negative correlation pairs (<0): Good hedges
- Portfolio diversification score: Average pairwise correlation (lower = better)
Phase 5: Concentration Risk
Evaluate concentration across multiple dimensions:
Position Concentration:
- Top holding as % of portfolio
- Top 3 holdings as % of portfolio
- Top 5 holdings as % of portfolio
- Herfindahl-Hirschman Index (HHI) calculation
Concentration Risk Levels:
| Metric | Low Risk | Medium Risk | High Risk |
|---|---|---|---|
| Top holding | <10% | 10-20% | >20% |
| Top 3 holdings | <30% | 30-50% | >50% |
| Top 5 holdings | <50% | 50-70% | >70% |
| HHI | <1000 | 1000-2500 | >2500 |
Single-stock risk flag: Any position >15% of portfolio gets a prominent warning.
Phase 6: Beta-Weighted Portfolio Delta
Calculate portfolio beta relative to benchmark:
- Look up beta for each holding via WebSearch
- Calculate weighted portfolio beta: Sum(position_weight * position_beta)
- Calculate beta-weighted portfolio delta:
- Portfolio delta = portfolio_value * weighted_beta
- Interpretation: "For every 1% move in SPY, your portfolio moves approximately X%"
Beta Assessment:
| Portfolio Beta | Interpretation |
|---|---|
| <0.5 | Very defensive — underperforms in bull markets |
| 0.5-0.8 | Defensive — lower volatility than market |
| 0.8-1.2 | Market-neutral — moves roughly with market |
| 1.2-1.5 | Aggressive — amplifies market moves |
| >1.5 | Very aggressive — high volatility exposure |
Phase 7: Dividend Analysis
For each dividend-paying holding:
- Current annual dividend per share
- Current yield
- Payout ratio
- Dividend growth rate (5-year CAGR)
- Years of consecutive increases
- Ex-dividend date (next)
Portfolio Income Summary:
- Total annual dividend income (pre-tax)
- Portfolio yield (weighted average)
- Monthly income estimate
- Yield on cost (if purchase prices provided)
- Income growth projection (1yr, 3yr, 5yr)
Dividend Safety Assessment:
| Payout Ratio | Safety Rating |
|---|---|
| <40% | Very Safe |
| 40-60% | Safe |
| 60-80% | Moderate Risk |
| >80% | High Risk |
| >100% | Unsustainable |
Phase 8: Benchmark Comparison
Compare portfolio to benchmark (default SPY) across:
| Metric | Portfolio | Benchmark | Delta |
|---|---|---|---|
| YTD Return | X% | Y% | +/-Z% |
| 1-Year Return | X% | Y% | +/-Z% |
| Beta | X | 1.00 | +/-Z |
| Dividend Yield | X% | Y% | +/-Z% |
| P/E Ratio (weighted) | X | Y | +/-Z |
| # of Holdings | X | ~500 | — |
Calculate tracking error and information ratio if sufficient data available.
Phase 9: Rebalancing Recommendations
Based on all analysis, provide specific recommendations:
Priority 1 — Risk Reduction (if needed):
- Reduce any position >20% of portfolio
- Add uncorrelated assets if average correlation >0.70
- Add defensive positions if beta >1.3 and goal is not aggressive growth
Priority 2 — Sector Gaps:
- Fill missing sectors that represent >5% of benchmark
- Reduce overweight sectors to within 5% of benchmark
- Suggest specific ETFs or stocks to fill gaps
Priority 3 — Income Optimization (if goal is income):
- Replace low-yield holdings with higher-yield alternatives
- Flag holdings with deteriorating dividend safety
- Suggest dividend growth stocks for compounding
Priority 4 — Tax Efficiency:
- Flag holdings with likely large gains (caution on selling)
- Suggest tax-loss harvesting candidates (if holding is down)
- Note wash sale rule considerations
For each recommendation:
- Specific action: "Reduce AAPL from 25% to 12% (~sell 60 shares)"
- Rationale: Why this improves the portfolio
- Alternative: If they cannot or prefer not to act

Rules
- ALWAYS use WebSearch for current market data — never fabricate prices or yields
- ALWAYS show both the current state AND what an optimized portfolio would look like
- ALWAYS include the disclaimer at the top and bottom of the report
- NEVER recommend specific buy/sell actions without noting they are suggestions, not advice
- ALWAYS note the date and time data was retrieved — market data is time-sensitive
- If a holding is not found or data is unavailable, note it and proceed with available data
- Round dollar values to 2 decimal places, percentages to 1 decimal place
- For ETFs, look through to underlying sector exposure rather than classifying the ETF itself
- Flag any holdings that may be duplicative (e.g., owning AAPL and a tech ETF heavy in AAPL)
- If the portfolio has fewer than 5 holdings, strongly recommend diversification
Error Handling
- Ticker not found: "Could not find data for [TICKER]. Skipping this holding. Please verify the ticker symbol."
- Price data stale: "Price data for [TICKER] may be delayed. Last available: $X on [DATE]."
- No holdings provided: Guide the user through the input format and ask them to provide holdings.
