By name: portfolio-audit description: Comprehensive portfolio risk audit. Computes single-name concentration, factor cluster exposure, leverage ETF decay risk, options Greeks aggregation, stress test scenarios (-10% SPX, yen carry, single-name miss), hedge effectiveness. Outputs explicit trim list with $ amounts and reasons + cash target. Triggers in English ("review my portfolio", "audit my book", "am I too concentrated", "what should I trim", "portfolio risk check") or Chinese ("审一下我的组合", "我组合风险大吗", "该减什么仓", "组合审计", "我哪里太集中").
Portfolio Audit — Full Risk Review
Goal
A fund-manager-level audit of the user's entire book. Answer 6 questions definitively:
- Where is concentration risk? (single-name + factor cluster)
- What blows up in -10% SPX day? (correlation unwind paths)
- What's the true equity beta? (incl. leverage ETFs and options delta)
- Where am I over-earning? (positions that have run too far)
- What hedges should I add? (gap protection)
- What trims should I execute today? (with $ amounts + tax considerations)
The 7-Step Workflow
Step 1 — Inventory the book
Get from user (or screenshot via review-investment-screenshot):
Stocks: ticker, qty, avg cost, current price, market value Options: ticker, strike, expiry, qty, cost, market value Cash + short-term: $ amount
Compute:
- Total equity value
- Cash %
- Stock %
- Options notional %
- Total leveraged exposure
Step 2 — Single-name concentration check
For each position, compute % of portfolio:
| % of book | Status | Action |
|---|---|---|
| < 3% | OK | None |
| 3-7% | Watching | Review thesis |
| 7-10% | Limit | Don't add |
| 10-15% | High | Trim to ≤10% |
| > 15% | EXTREME | Force trim to 10% (unless explicit conviction & long-term) |
Exception: User-defined "core hold" with locked thesis (e.g., NOK 19% with 1Y target $20+) — note but don't force trim.
Step 3 — Factor cluster analysis
Group positions into factor clusters:
Standard clusters for 2026:
- AI Semis (NVDA, AMD, AVGO, MU, AMUU, MSFU等杠杆 ETF)
- AI Compute / Cloud (ORCL, CRWV, NBIS, IREN, APLD)
- AI Network (TEL, ANET, CIEN, FN, HPE, NOK)
- AI Power (CEG, VST, EQT, AEP, ETR, LEU)
- AI Materials (HBM, FCX, APD, MP)
- Crypto-adjacent (COIN, HOOD, MSTR)
- Speculative growth (AFRM, SOFI, U)
- Mega-tech (GOOGL, MSFT, META, AAPL, AMZN)
- China (BABA, JD, PDD, BIDU)
- Defense/Aerospace (LMT, CSTM)
Aggregation rule:
- Same factor cluster > 25% = one bet regardless of how many tickers
- Recommend trim or cross-cluster diversification
Step 4 — Leverage / volatility decay check
Flag any:
- Daily-reset 2x/3x ETFs (MSFU, AMUU, GDXU, SOXL, TQQQ, NVDL等)
- Held >2 weeks (vol decay accumulates)
- Up >20% (rotate to LEAPS for cleaner exposure)
Action: Most leverage ETFs should be closed and rotated to LEAPS on the underlying.
Step 5 — Options aggregation (Greeks-aware)
For each option position:
- Delta (estimate): ATM = 0.5, OTM 10% = 0.35, OTM 20% = 0.25, deep ITM = 0.85
- Notional exposure: contracts × 100 × strike (full notional)
- Delta-weighted exposure: notional × delta (true equity equivalence)
- Theta risk: short-dated (< 30 days) = high decay
- IV exposure: post-earnings IV crush risk
Aggregate by underlying: if user has 6 NVDA LEAPS + 350 stock + AMD LEAPS, what's the combined NVDA+AMD delta?
Step 6 — Stress test scenarios
For each scenario, compute estimated portfolio impact:
| Scenario | What happens | Impact estimate |
|---|---|---|
| SPX -5% | Mild correction | Use beta × -5% |
| SPX -10% | Standard pullback | Beta × -10% + leverage ETF decay |
| NDX -15% (tech rotation) | Mag7/AI sells off | Heavy if cluster >30% AI |
| Yen carry unwind (USD/JPY <153) | -8 to -22% on AI semis | Compute by sector exposure |
| Single name -30% (e.g., NVDA earnings miss) | If concentrated | Show $ loss |
| VIX > 30 (volatility regime change) | Options IV crush + delta loss | Compute by options exposure |
| OPEC + 1973 重演 | Energy spike + risk-off | Show defensive vs growth |
Output: "In a -10% SPX day, your book loses ~$X (X% of total)."
Step 7 — Generate trim list + hedge recommendations
Trim list (specific orders):
| Ticker | Qty | $ proceeds | Rule fired | Tax impact |
|---|
Hedge recommendations:
| Hedge | Cost | Coverage | Why |
|---|---|---|---|
| SPY 6/18 $XXX Put × N | $X,XXX | Index gap | Macro red signal |
| Underlying-specific puts | If single name 10%+ |
Cash target:
- Risk-on regime → 5-15% cash
- Late-cycle / yellow → 20-30%
- Yellow + binary events → 30-40%
- Red regime / crisis → 40-60%

Hard rules (the trim ladder)
Run every position through this in order. Call the FIRST rule that fires:
| # | Condition | Action |
|---|---|---|
| 1 | Daily-reset leveraged ETF held >2 weeks AND up >20% | Trim 50%+, rotate to LEAPS |
| 2 | Position up >100% unrealized | Sell at least 1/3 to recover cost basis |
| 3 | Position up >50% AND single-name >10% of book | Trim to ≤10% |
| 4 | Single factor cluster >25% of book | Reduce to ≤20% by trimming most-extended in cluster |
| 5 | At 1-year high AND earnings within 7 days | Trim 25-50% before print |
| 6 | Up >30% AND >40% above 200DMA (parabolic) | Trim 25% OR set hard stop at MA20 |
| 7 | Portfolio total unrealized >20% AND macro = late-cycle euphoria | Reduce gross 10-15% via index hedge |
| 8 | Up >20% but thesis broken (below MA50 in downtrend OR narrative shift) | Exit 50%+ immediately |
| 9 | Underwater >15% AND bear case confirmed by price | Cut. Don't average |
| 10 | None of above | Hold. State trailing stop level |
Macro contextual overlays
Adjust trim aggressiveness based on macro signals (run macro-risk-check first):
- Yen carry risk active (USD/JPY < 153): Reduce semi-cluster to <20%
- Pre-major central bank meeting: Cash target 30%+
- Pre-major geopolitical summit: Hold core thesis names for upside optionality
- Energy/oil supply shock active: Defensive + reduce growth allocation
Common pitfalls
| Pitfall | Example | Lesson |
|---|---|---|
| Counting tickers as diversification | 6 AI semis = "diversified" | One bet |
| Ignoring options notional | $50K LEAPS = $200K delta | Use Greeks |
| Trim winners, hold losers | Sell NVDA +20%, hold INTC -50% | Reverse — trim losers, ride winners (with stops) |
| Over-trim during stress | Sell 50% on -3% day | Wait for trigger or hedge instead |
| No tax plan | Sell 1000 NOK STCG vs LTCG | Lose 12-15% to tax |
| Hedge after the move | Buy puts after -10% drop | Should be pre-event, not reactive |

When to invoke
- User asks: "Review my portfolio"
- User asks: "Am I too concentrated"
- User asks: "What should I trim"
- User asks: "Should I hedge"
- After macro-risk-check shows YELLOW or worse
- Monthly (recommended)
- Pre-major event (Fed, BOJ, Trump-Xi, earnings cluster)
- After any position becomes >15% of book (auto-trigger)
