institutional-flow-tracker

institutional-flow-tracker is a skill for Claude Code from mphinance/alpha-skills. It costs 64 tokens per session (3,289 once invoked), scanned A, a copy of institutional-flow-tracker, MIT.

A tracker that compares quarterly SEC 13F filings to show how institutional investors change their stock holdings. Institutional investors include organisations such as hedge funds, mutual funds, and pension funds.

In plain words
What is it for?
Use it to find stocks with notable institutional accumulation or selling, check whether institutions support an investment idea, and identify holdings that may need risk review.
Why use it?
It makes changes in reported institutional ownership easier to compare over time. This can help with portfolio monitoring and investment research, but it does not by itself explain why an investor changed a position.

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

institutional-flow-tracker 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 10 executable files (scripts/analyze_single_stock.py, scripts/data_quality.py, scripts/tests/conftest.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.

Institutional Flow Tracker

Overview

This skill tracks institutional investor activity through 13F SEC filings to identify "smart money" flows into and out of stocks. By analyzing quarterly changes in institutional ownership, you can discover stocks that sophisticated investors are accumulating before major price moves, or identify potential risks when institutions are reducing positions.

Key Insight: Institutional investors (hedge funds, pension funds, mutual funds) manage trillions of dollars and conduct extensive research. Their collective buying/selling patterns often precede significant price movements by 1-3 quarters.

Prerequisites

  • FMP API Key: Set FMP_API_KEY environment variable or pass --api-key to scripts
  • Python 3.8+: Required for running analysis scripts
  • Dependencies: pip install requests (scripts handle missing dependencies gracefully)

When to Use This Skill

Use this skill when:

  • Validating investment ideas (checking if smart money agrees with your thesis)
  • Discovering new opportunities (finding stocks institutions are accumulating)
  • Risk assessment (identifying stocks institutions are exiting)
  • Portfolio monitoring (tracking institutional support for your holdings)
  • Following specific investors (tracking Warren Buffett, Cathie Wood, etc.)
  • Sector rotation analysis (identifying where institutions are rotating capital)

Do NOT use when:

  • Seeking real-time intraday signals (13F data has 45-day reporting lag)
  • Analyzing micro-cap stocks (<$100M market cap with limited institutional interest)
  • Looking for short-term trading signals (<3 months horizon)

Data Sources & Requirements

Required: FMP API Key

This skill uses Financial Modeling Prep (FMP) API to access 13F filing data:

Setup:

# Set environment variable (preferred)
export FMP_API_KEY=your_key_here

# Or provide when running scripts
python3 scripts/track_institutional_flow.py --api-key YOUR_KEY

API Tier Requirements:

  • Free Tier: 250 requests/day (sufficient for analyzing 20-30 stocks quarterly)
  • Paid Tiers: Higher limits for extensive screening
