Portfolio Analysis

Analyze the user's investment portfolio.

Step 1: Get Portfolio Data

Ask the user how they want to provide portfolio data:

• A) Upload a CSV file (Zerodha Console, Groww, Angel One, or custom format with columns: ticker, shares, cost_basis)
• B) Paste holdings manually (format: TICKER SHARES COST_BASIS)
• C) Load from saved portfolio in ~/.wealthstack/portfolios/

Parse the data. For NSE stocks, append .NS to tickers. Save to ~/.wealthstack/portfolios/.

Step 2: Fetch Market Data

bash ${CLAUDE_PLUGIN_ROOT}/scripts/fetch-quotes.sh TICKER1.NS TICKER2.NS ...

Step 3: Analyze

Compute and present:

• Holdings table: Ticker, Shares, Cost Basis, Current Value, Gain/Loss (%), Weight
• Allocation: By asset class, sector (BFSI/IT/Pharma/Auto/FMCG etc.), market cap (large/mid/small)
• Performance: Total return, XIRR, top/bottom performers, benchmark comparison vs Nifty 50
• Concentration flags: Single stock >10%, single sector >30%, top 5 >50%

Step 4: Recommendations

Provide actionable recommendations: diversification gaps, overweight positions, high expense ratio funds to replace, tax-loss harvesting candidates.

Present all amounts in INR (Rs) with Indian numbering (lakhs, crores).
