Stage Analysis for Claude Code

Stan Weinstein Stage Analysis skill for Claude Code. Automated stage classification (1-4), emoji summary tables, 3-tier sector breadth scanning, and actionable buy/sell signals.

What It Does

• Classifies any stock/ETF into Weinstein Stage 1-4 using weekly data
• Computes 30w/10w/20d EMAs, slopes, volume ratios, relative strength vs S&P 500
• Generates emoji summary tables for quick visual scanning
• 3-tier sector breadth scan (market-level, sector ETF, constituent-level)
• Auto-resolves ETF holdings for constituent scans (--etf MOO)
• Supports UCITS European ETFs with exchange suffixes (.DE, .L, .MI)

python3 scripts/fetch_stage_data.py --sector-scan 1

# ETF constituent scan
python3 scripts/fetch_stage_data.py --etf GDX

# Specific constituents
python3 scripts/fetch_stage_data.py --sector-scan 3 NTR MOS CF SQM ICL

Methodology

Based on Stan Weinstein's "Secrets for Profiting in Bull and Bear Markets." The Methodology.md file covers:

• Four stages and transition signals
• Moving average framework (30w, 10w, 20d EMAs)
• Volume analysis and breakout confirmation
• Relative strength vs S&P 500
• 20-day EMA as power trend and sector breadth scanner
• Coincident and divergent action for signal confirmation
• Failed breakout/breakdown pattern recognition
• 2-year resistance lookback rule
• Gap-up breakout entry patterns
• Market breadth thresholds
• Rally duration rule (3-5 month cycles)
• Risk management

Output Format

The skill produces emoji summary tables:

| Ticker | Stg | Price   | MAs      | Slope | Vol | RS | PPO | 52wH | Signal   |
|--------|-----|---------|----------|-------|-----|-----|-----|------|----------|
