xonevn-ai Macro Regime Detector
Detect structural macro regime transitions using monthly-frequency cross-asset ratio analysis. This skill identifies 1-2 year regime shifts that inform strategic portfolio positioning.
When to Use
- User asks about current macro regime or regime transitions
- User wants to understand structural market rotations (concentration vs broadening)
- User asks about long-term positioning based on yield curve, credit, or cross-asset signals
- User references RSP/SPY ratio, IWM/SPY, HYG/LQD, or other cross-asset ratios
- User wants to assess whether a regime change is underway
Workflow
Load reference documents for methodology context:
references/regime_detection_methodology.mdreferences/indicator_interpretation_guide.md
Execute the main analysis script:
python3 skills/macro-regime-detector/scripts/macro_regime_detector.pyThis fetches 600 days of data for 9 ETFs + Treasury rates (10 API calls total).
Read the generated Markdown report and present findings to user.
Provide additional context using
references/historical_regimes.mdwhen user asks about historical parallels.
Prerequisites
- FMP API Key (required): Set
FMP_API_KEYenvironment variable or pass--api-key - Free tier (250 calls/day) is sufficient (script uses ~10 calls)
6 Components
| # | Component | Ratio/Data | Weight | What It Detects |
|---|---|---|---|---|
| 1 | Market Concentration | RSP/SPY | 25% | Mega-cap concentration vs market broadening |
| 2 | Yield Curve | 10Y-2Y spread | 20% | Interest rate cycle transitions |
| 3 | Credit Conditions | HYG/LQD | 15% | Credit cycle risk appetite |
| 4 | Size Factor | IWM/SPY | 15% | Small vs large cap rotation |
| 5 | Equity-Bond | SPY/TLT + correlation | 15% | Stock-bond relationship regime |
| 6 | Sector Rotation | XLY/XLP | 10% | Cyclical vs defensive appetite |
5 Regime Classifications
- Concentration: Mega-cap leadership, narrow market
- Broadening: Expanding participation, small-cap/value rotation
- Contraction: Credit tightening, defensive rotation, risk-off
- Inflationary: Positive stock-bond correlation, traditional hedging fails
- Transitional: Multiple signals but unclear pattern
