Format A (Shares):

AAPL 100
MSFT 50
VTI 200

Format B (Dollar Amounts):

AAPL $15,000
MSFT $20,000
VTI $30,000

Also ask (optional): investment goal (growth/income/preservation/balanced), time horizon, risk tolerance, benchmark preference (default: SPY), any positions they cannot sell.

Analysis Process

Phase 1: Position Mapping

For each holding, use web_search for: current price, sector (GICS), market cap category, country/region, asset class, dividend yield.

Phase 2: Sector Allocation Analysis

Map to 11 GICS sectors and compare to SPY benchmark weights. Flag:

• Overweight: >5% above benchmark
• Underweight: >5% below benchmark
• Missing: 0% where benchmark has >3%

Phase 3: Geographic Exposure

Classify: US Domestic (>70% US revenue), International Developed, Emerging Markets, Global Diversified.

Phase 4: Correlation Analysis

Find correlation data between major holdings. Build simplified matrix. Flag:

• High correlation pairs (>0.80): No meaningful diversification
• Negative correlation (<0): Good hedges
• Portfolio diversification score: Average pairwise correlation

Phase 5: Concentration Risk

• Top holding, top 3, top 5 as % of portfolio
• Herfindahl-Hirschman Index (HHI)

Metric	Low Risk	Medium Risk	High Risk
Top holding	<10%	10-20%	>20%
Top 3 holdings	<30%	30-50%	>50%
HHI	<1000	1000-2500	>2500

Flag any single position >15% prominently.

Phase 6: Beta-Weighted Portfolio Delta

• Look up beta for each holding
• Calculate: weighted portfolio beta = Σ(position_weight × position_beta)
• Interpretation: "For every 1% move in SPY, your portfolio moves approximately X%"

Phase 7: Dividend Analysis

For each dividend-paying holding: yield, payout ratio, growth rate (5Y CAGR), next ex-dividend date. Portfolio Income: Total annual dividends, weighted yield, monthly income estimate, income growth projection (1/3/5 yr).

Phase 8: Benchmark Comparison

Compare portfolio vs SPY: YTD return, beta, dividend yield, P/E (weighted), # of holdings.

Phase 9: Rebalancing Recommendations

Priority 1 — Risk Reduction: Reduce positions >20%; add uncorrelated assets if avg correlation >0.70. Priority 2 — Sector Gaps: Fill missing sectors >5% of benchmark; reduce overweight sectors. Priority 3 — Income Optimization (if goal is income): Replace low-yield with higher-yield; flag deteriorating dividend safety. Priority 4 — Tax Efficiency: Flag large-gain positions (caution on selling); suggest tax-loss harvesting candidates.

Rules

1. ALWAYS use web_search for current prices — never fabricate.
2. ALWAYS show current state AND what optimized portfolio would look like.
3. If fewer than 5 holdings, strongly recommend diversification.
4. For ETFs, look through to underlying sector exposure.
5. Flag any duplicative positions (owning AAPL and a tech ETF heavy in AAPL).
