Assess portfolio and position risk using neural-trader's risk engine.

Steps:

1. Ensure neural-trader is available: npm ls neural-trader 2>/dev/null || npm install --ignore-scripts neural-trader
2. Run risk assessment:

   # Single position
   npx neural-trader --risk assess --symbol TICKER
   npx neural-trader --var --symbol TICKER --investment 10000
   
   # Portfolio-wide
   npx neural-trader --risk assess --portfolio NAME
   npx neural-trader --correlation --portfolio NAME --flag-threshold 0.8
   

3. Calculate position sizing:

   npx neural-trader --risk-tolerance 0.02 --symbol TICKER
   npx neural-trader --position-sizing kelly --symbol TICKER
   

4. Check circuit breaker status:
   • Daily loss limit (3%), weekly loss limit (5%)
   • Correlation spike (>0.85), volatility regime (VIX > 2x)
   • Max positions, single-name concentration (>10%)
5. Present: risk metrics, position sizing recommendation, active breakers, alerts
6. Store assessment: mcp__claude-flow__memory_store({ key: "risk-TICKER-DATE", value: "RISK_METRICS", namespace: "trading-risk" })
