sector-analyst is a skill for Claude Code from mphinance/alpha-skills. It costs 84 tokens per session (1,819 once invoked), scanned A, original, MIT.

A market-sector analysis tool that ranks sectors and estimates whether market leadership is shifting toward cyclical or defensive areas. It uses public uptrend data and can also consider chart images.

In plain words
What is it for?
Use it to study sector rotation, compare cyclical and defensive positioning, assess overbought or oversold sectors, and examine sector charts for additional industry detail.
Why use it?
It provides a structured view of which sectors are leading, overbought, or oversold instead of judging the whole market from individual stocks. It also estimates the current phase of the market cycle.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sector-analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/analyze_sector_rotation.py, scripts/tests/conftest.py, scripts/tests/helpers.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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 3.8+ with requests library (for CSV fetching)
  • 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

# 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/
