## What it does

The skill examines RSP/SPY, the yield curve, HYG/LQD, IWM/SPY, the SPY/TLT relationship, and XLY/XLP. It classifies signals as Concentration, Broadening, Contraction, Inflationary, or Transitional, then produces evidence for the current assessment.

It reads methodology and indicator guides before running its Python script. The script fetches 600 days of data for 9 ETFs and writes Markdown and JSON reports to the selected output directory. Historical comparisons draw on `references/historical_regimes.md`.

Install dependencies from `requirements.txt`, including `yfinance` and `requests`. An `FMP_API_KEY` is optional: it tries FMP and Treasury data first, then uses `yfinance` with SHY/TLT as the yield-curve fallback. A missing report means the data should be checked, not interpreted as a low-transition regime.

## Install

### Claude Code (native platform)

```bash
npx skills add tradermonty/claude-trading-skills --skill macro-regime-detector -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/macro-regime-detector/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/macro-regime-detector/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tradermonty/claude-trading-skills --skill macro-regime-detector -a codex
```

2. **Manually: put the files in place**

## When to use it
- assess the current structural macro regime
- detect a shift from concentration to market broadening
- compare yield-curve and credit-condition signals
- check small-cap versus large-cap rotation
- generate a cross-asset regime report

## Example prompts
- Assess the current macro regime and show transition signals.
- Check whether a structural shift from Concentration to Broadening is underway.
- Analyze RSP/SPY, HYG/LQD, and IWM/SPY for long-term positioning.

description: Detect structural macro regime transitions (1-2 year horizon) using cross-asset ratio analysis. Analyze RSP/SPY concentration, yield curve, credit conditions, size factor, equity-bond relationship, and sector rotation to identify regime shifts between Concentration, Broadening, Contraction, Inflationary, and Transitional states. Run when user asks about macro regime, market regime change, structural rotation, or long-term market positioning.

# 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

1. Load reference documents for methodology context:
   - `references/regime_detection_methodology.md`
   - `references/indicator_interpretation_guide.md`

2. Execute the main analysis script:
   ```bash
   python3 -m pip install -r skills/macro-regime-detector/requirements.txt
   uv run python3 skills/macro-regime-detector/scripts/macro_regime_detector.py --output-dir reports/
   ```
   This fetches 600 days of data for 9 ETFs. With an FMP key, the client tries
   FMP first and fetches Treasury rates (~10 API calls total), then falls back
   to yfinance for unavailable ETF history. Without an FMP key, it runs in
   yfinance-only mode and uses SHY/TLT as the yield-curve fallback.

   The detector fails closed and writes no report when none of its six
   components has usable data. Do not treat a missing report or non-zero exit
   as a valid low-transition regime.

3. Read the generated Markdown report and present findings to user.

4. Provide additional context using `references/historical_regimes.md` when user asks about historical parallels.

## Prerequisites

- **Python dependencies** (required): install `requirements.txt`, including yfinance and requests
- **FMP API Key** (optional): set `FMP_API_KEY` or pass `--api-key` to use FMP and Treasury data before the yfinance/SHY-TLT fallbacks
- The FMP free tier may not serve every ETF; unavailable symbols automatically use yfinance
