## What it does

This skill fetches sector uptrend ratios from CSV data, ranks sectors, and calculates a cyclical-versus-defensive regime score. It also flags overbought and oversold sectors, estimates the market-cycle phase, and reports a confidence level.

It runs through `scripts/analyze_sector_rotation.py`, with console, JSON, and saved-report modes. The skill refers to `references/sector_rotation.md` for cycle frameworks, while supplied chart images can add industry-level observations.

Python 3.9+ is required. It uses the standard library for CSV retrieval and needs no API key because the data comes from a public repository. Its analysis and output are in English, so that is a reason to check whether the format fits your workflow.

# Sector Analyst

## Overview

This skill enables comprehensive analysis of sector rotation and market cycle positioning by fetching uptrend ratio data from TraderMonty's public CSV dataset. It ranks sectors, calculates cyclical vs defensive risk regime scores, identifies overbought/oversold conditions, and estimates the current market cycle phase. Chart images can optionally supplement the data-driven analysis with industry-level detail.

## When to Use This Skill

Use this skill when:
- User requests sector rotation analysis (no chart images required)
- User asks about cyclical vs defensive positioning
- User wants to know which sectors are overbought or oversold
- User requests market cycle phase estimation
- User provides sector performance charts for supplementary analysis
- User asks for sector-based scenario analysis or predictions

Example user requests:
- "Run a sector rotation analysis"
- "Which sectors are leading — cyclical or defensive?"
- "Are any sectors overbought right now?"
- "What phase of the market cycle are we in?"
- "Analyze these sector performance charts and tell me where we are in the market cycle"

## Prerequisites

- **Python 3.9+**; no third-party libraries required (CSV fetched via stdlib `urllib`)
- **No API keys required** — data is fetched from a public GitHub repository
- **Optional**: Sector performance chart images for supplementary analysis

## Data Source

Sector uptrend ratios are fetched from TraderMonty's public GitHub repository (no API key required):
- **Sector Summary**: `sector_summary.csv` — uptrend ratio, trend, slope, and status per sector
- **Freshness Check**: `uptrend_ratio_timeseries.csv` — max(date) used to verify data recency

## Running the Script

```bash
# Default: fetch CSV, print human-readable analysis
python3 scripts/analyze_sector_rotation.py

# JSON output
python3 scripts/analyze_sector_rotation.py --json

# Save to file
python3 scripts/analyze_sector_rotation.py --save --output-dir reports/
```

## Analysis Workflow

Follow this structured workflow:

### Step 1: CSV Data Collection

1. Run the analysis script: `python3 scripts/analyze_sector_rotation.py`
2. Extract from the output:
   - Sector ranking by uptrend ratio
   - Risk regime (cyclical vs defensive) and score
   - Overbought/oversold sectors
   - Cycle phase estimate and confidence level
3. If a data freshness warning appears, note it in the analysis

### Step 2: Market Cycle Assessment
