# Risk Portfolio Manager - AI-Driven Risk Control

Systematic risk management layer that sits between signal generation and trade execution. Uses data-driven approaches to optimize position sizing, manage portfolio risk, and automate defensive actions.

## Core Principle

> Position sizing and risk management determine long-term survival. No single trade should threaten the portfolio.

## Activation Triggers

<triggers>
- "Size this position"
- "What's my portfolio risk?"
- "Rebalance my holdings"
- "Calculate VaR"
- "Should I take profit?"
- "Set up risk limits"
- "Portfolio correlation check"
- "Daily loss limit"
- Keywords: position size, risk management, portfolio, allocation, drawdown, VaR, Sharpe, rebalance, stop loss, take profit, correlation, diversification
</triggers>

## Core Capabilities

### 1. Position Sizing Engine

<position_sizing>
**Sizing Methods:**

```typescript
interface PositionSizeRequest {
  signal_strength: number;    // 0-1 from meme-trader
  token_risk_score: number;   // 1-10 from rug detection
  current_portfolio: Portfolio;
  market_regime: 'bull' | 'bear' | 'sideways' | 'volatile';
  risk_tolerance: 'conservative' | 'moderate' | 'degen';
}

interface PositionSizeResult {
  recommended_size_pct: number;  // % of portfolio
  recommended_size_usd: number;
  max_allowed_size: number;
  reasoning: string[];
  risk_warnings: string[];
}
```

**Kelly Criterion (Modified):**
```
Optimal Size = (Win Rate * Avg Win - (1 - Win Rate) * Avg Loss) / Avg Win
Adjusted Size = Kelly * Fractional Multiplier (0.25-0.5 for safety)
```

**Risk-Adjusted Sizing Matrix:**
| Risk Tolerance | Base Size | Max Single Position | Max Correlated Exposure |
|---------------|-----------|--------------------|-----------------------|
| Conservative | 0.5-1% | 2% | 5% |
| Moderate | 1-2% | 4% | 10% |
| Degen | 2-5% | 10% | 25% |

**Signal-Based Adjustments:**
```
Final Size = Base Size * Signal Strength * (1 - Token Risk / 20) * Market Multiplier

Where:
- Signal Strength: 0.5-1.5 (weak to strong)
- Token Risk: 1-10 (lower is safer)
- Market Multiplier: 0.5 (volatile) to 1.2 (trending)
```

**Output Format:**
```
POSITION SIZE RECOMMENDATION

Token: $MEME
Signal Strength: 8/10
Token Risk Score: 4/10
Market Regime: BULL

RECOMMENDED SIZE:
├─ Percentage: 2.3% of portfolio
├─ Amount: $460 (of $20,000 portfolio)
├─ Max Allowed: $800 (4% limit)
└─ Risk-Adjusted: WITHIN LIMITS

REASONING:
1. Strong signal (8/10) supports above-average sizing
2. Low-medium risk token (4/10) allows full allocation
3. Bull market regime permits aggressive sizing
4. No correlation with existing positions

WARNINGS:
- Consider scaling in (3 tranches) vs single entry
- Set stop-loss at -25% ($345 max loss)
```
</position_sizing>

ALERTS:
⚠️ High correlation between MEME and WIF (0.85)
⚠️ Meme sector concentration above 50%
```

**Risk Calculations:**
```typescript
interface PortfolioRisk {
  // Value at Risk
  var_95: number;       // 95% confidence daily VaR
  var_99: number;       // 99% confidence daily VaR
  cvar_95: number;      // Conditional VaR (expected shortfall)

  // Performance Risk
  sharpe_ratio: number;
  sortino_ratio: number;
  max_drawdown: number;
  current_drawdown: number;

  // Correlation Risk
  avg_correlation: number;
  max_correlation: number;
  correlation_cluster: string[]; // Highly correlated groups

  // Concentration Risk
  herfindahl_index: number;
  top_position_pct: number;
  sector_concentrations: Record<string, number>;
}

function calculateVaR(
  positions: Position[],
  confidence: number = 0.95,
  horizon_days: number = 1
): number {
  // Historical VaR using past 30 days of returns
  const returns = getHistoricalReturns(positions, 30);
  const portfolio_returns = calculatePortfolioReturns(returns, positions);
  const sorted = portfolio_returns.sort((a, b) => a - b);
  const index = Math.floor((1 - confidence) * sorted.length);
  return sorted[index] * getPortfolioValue(positions) * Math.sqrt(horizon_days);
}
```
</risk_metrics>

### 3. Dynamic Rebalancing

<rebalancing>
**Rebalancing Triggers:**
- Drift > 5% from target allocation
- Single position > max limit
- Correlation spike > 0.9 between positions
- Sector concentration > threshold
- Weekly scheduled review

**Target Allocation Framework:**
```typescript
interface AllocationTarget {
  core_holdings: {
    SOL: { target: 30, min: 20, max: 50 };
    stablecoins: { target: 20, min: 10, max: 40 };
  };
  satellite_holdings: {
    memes: { target: 30, min: 0, max: 50 };
    defi: { target: 15, min: 0, max: 30 };
    other: { target: 5, min: 0, max: 15 };
  };
  rebalance_threshold: 5; // % drift to trigger
}
```

**Rebalancing Output:**
```
REBALANCING RECOMMENDATION

Current vs Target Allocation:
Category     | Current | Target | Drift  | Action
SOL          | 37%     | 30%    | +7%    | SELL $1,400
Memes        | 63%     | 50%    | +13%   | SELL $2,600
Stables      | 0%      | 20%    | -20%   | BUY $4,000

SUGGESTED TRADES:
1. SELL 15% of BONK position ($630) → USDC
2. SELL 20% of WIF position ($500) → USDC
3. SELL 10% of SOL position ($740) → USDC
4. Keep MEME and DOGE positions
5. Convert sales to USDC stablecoin buffer

POST-REBALANCE PROJECTION:
├─ SOL: 31% (target: 30%)
├─ Memes: 48% (target: 50%)
├─ Stables: 21% (target: 20%)
└─ VaR Reduction: -18% (improved risk profile)
```
</rebalancing>

### 4. Automated Defensive Actions

<defensive_actions>
**Kill Switch System:**
```typescript
interface KillSwitchConfig {
  daily_loss_limit: number;      // % of portfolio
  weekly_loss_limit: number;     // % of portfolio
  position_loss_limit: number;   // % per position
  drawdown_limit: number;        // % from peak
  correlation_spike_action: 'alert' | 'reduce' | 'exit';
  auto_execute: boolean;
}

const defaultKillSwitch: KillSwitchConfig = {
  daily_loss_limit: 10,      // Halt new trades at -10% day
  weekly_loss_limit: 20,     // Halt all activity at -20% week
  position_loss_limit: 30,   // Auto-close position at -30%
  drawdown_limit: 25,        // Emergency mode at -25% from peak
  correlation_spike_action: 'alert',
  auto_execute: false,       // Require confirmation in Phase 1
};
```

**Triggered Actions:**
| Trigger | Action | Severity |
|---------|--------|----------|
| Position -25% | Stop-loss warning | MEDIUM |
| Position -30% | Auto-close (if enabled) | HIGH |
| Daily -10% | Halt new trades | HIGH |
| Weekly -20% | Exit to stables | CRITICAL |
| Drawdown -25% | Emergency liquidation | CRITICAL |
| Correlation > 0.95 | Reduce one position | MEDIUM |

**Alert Output:**
```
🚨 RISK ALERT: DAILY LOSS LIMIT APPROACHING

Current Day PnL: -8.7% ($-1,740)
Daily Limit: -10% ($-2,000)
Buffer Remaining: $260

TRIGGERED ACTIONS:
1. ⏸️ New trade execution PAUSED
2. ⚠️ Review all open positions
3. 📊 Increased monitoring frequency

RECOMMENDED:
- Review worst performing position (WIF: -15%)
- Consider partial exit if trend continues
- DO NOT average down

Type RESUME to re-enable trading
Type EXIT_ALL to liquidate positions
```
</defensive_actions>

### 5. Scenario Analysis

<scenario_analysis>
**Stress Testing:**
```typescript
interface StressScenario {
  name: string;
  market_move: {
    sol: number;      // % change
    memes: number;    // % change vs SOL
    correlation_shift: number;
  };
  probability: number;
}

const stressScenarios: StressScenario[] = [
  {
    name: 'SOL -30% Flash Crash',
    market_move: { sol: -30, memes: -50, correlation_shift: 0.2 },
    probability: 0.05,
  },
  {
    name: 'Meme Rotation Out',
    market_move: { sol: 0, memes: -40, correlation_shift: -0.1 },
    probability: 0.10,
  },
  {
    name: 'Bull Run Continuation',
    market_move: { sol: 50, memes: 100, correlation_shift: 0 },
    probability: 0.15,
  },
  {
    name: 'Black Swan Event',
    market_move: { sol: -60, memes: -80, correlation_shift: 0.3 },
    probability: 0.01,
  },
];
```

**Stress Test Output:**
```
STRESS TEST RESULTS

Current Portfolio Value: $20,000

SCENARIO                    | Portfolio Impact | Probability
SOL -30% Flash Crash        | -$7,200 (-36%)   | 5%
Meme Rotation Out           | -$5,040 (-25%)   | 10%
Bull Run Continuation       | +$14,600 (+73%)  | 15%
Black Swan Event            | -$12,400 (-62%)  | 1%

EXPECTED PORTFOLIO VALUE:
├─ Base Case: $20,000
├─ Expected (prob-weighted): $22,340 (+11.7%)
├─ Worst Case (99%): -$12,400 (-62%)
└─ VaR (95%, 30d): -$4,800 (-24%)

RISK ASSESSMENT:
⚠️ High sensitivity to meme rotation (-25% scenario)
⚠️ Black swan exposure significant (-62%)
✓ Positive expected value in base scenarios
✓ Bull case upside substantial (+73%)

RECOMMENDATION:
Consider hedging meme exposure with SOL puts or reducing
meme allocation by 10-15% to improve risk profile.

```

## Quality Gates

<validation_rules>
- Position sizing requires quality score >= 85% on price data
- VaR calculations require 30+ days of clean historical data
- Correlation matrix requires synchronized price data
- All recommendations include confidence levels
- No position sizing without rug detection check
</validation_rules>

## Error Handling

<error_recovery>
- Missing price data: Use last known + stale warning
- Calculation error: Conservative fallback (minimum size)
- Kill switch conflict: Safety wins (halt > continue)
- Data quality insufficient: Reject sizing, request refresh
</error_recovery>
