# 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.

## 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:**
```bash
# 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

**13F Filing Schedule:**
- Filed quarterly within 45 days after quarter end
- Q1 (Jan-Mar): Filed by mid-May
- Q2 (Apr-Jun): Filed by mid-August
- Q3 (Jul-Sep): Filed by mid-November
- Q4 (Oct-Dec): Filed by mid-February

## Analysis Workflow

### Step 1: Identify Stocks with Significant Institutional Changes

Execute the main screening script to find stocks with notable institutional activity:

**Quick scan (top 50 stocks by institutional change):**
```bash
python3 institutional-flow-tracker/scripts/track_institutional_flow.py \
  --top 50 \
  --min-change-percent 10
```

**Sector-focused scan:**
```bash
python3 institutional-flow-tracker/scripts/track_institutional_flow.py \
  --sector Technology \
  --min-institutions 20
```

**Custom screening:**
```bash
python3 institutional-flow-tracker/scripts/track_institutional_flow.py \
  --min-market-cap 2000000000 \
  --min-change-percent 15 \
  --top 100 \
  --output institutional_flow_results.json
```

**Output includes:**
- Stock ticker and company name
- Current institutional ownership % (of shares outstanding)
- Quarter-over-quarter change in shares held
- Number of institutions holding
- Change in number of institutions (new buyers vs sellers)
- Top institutional holders
- Aggregate dollar value change

### Step 2: Deep Dive on Specific Stocks

For detailed analysis of a specific stock's institutional ownership:

```bash
python3 institutional-flow-tracker/scripts/analyze_single_stock.py AAPL
```

**This generates:**
- Historical institutional ownership trend (8 quarters)
- List of all institutional holders with position changes
- Concentration analysis (top 10 holders' % of total institutional ownership)
- New positions vs increased vs decreased vs closed positions
- Quarterly flow chart (net shares added/removed)
- Comparison to sector average institutional ownership

**Key metrics to evaluate:**
- **Ownership %:** Higher institutional ownership (>70%) = more stability but limited upside
- **Ownership Trend:** Rising ownership = bullish, falling = bearish
- **Concentration:** High concentration (top 10 > 50%) = risk if they sell
- **Quality of Holders:** Presence of quality long-term investors (Berkshire, Fidelity) vs momentum funds

### Step 3: Track Specific Institutional Investors

Follow the portfolio moves of specific hedge funds or investment firms:

```bash
# Track Warren Buffett's Berkshire Hathaway
python3 institutional-flow-tracker/scripts/track_institution_portfolio.py \
  --cik 0001067983 \
  --name "Berkshire Hathaway"

# Track Cathie Wood's ARK Investment Management
python3 institutional-flow-tracker/scripts/track_institution_portfolio.py \
  --cik 0001579982 \
  --name "ARK Investment Management"
```

**CIK (Central Index Key) lookup:**
- Search at: https://www.sec.gov/cgi-bin/browse-edgar
- Or use FMP API institutional search

**Analysis output:**
- Current portfolio holdings (top 50 positions)
- New positions added this quarter
- Positions completely sold
- Largest increases/decreases in existing positions
- Portfolio concentration and sector allocation changes
- Historical performance of their top picks

### Step 4: Interpretation and Action

Read the references for interpretation guidance:
- `references/13f_filings_guide.md` - Understanding 13F data and limitations
- `references/institutional_investor_types.md` - Different investor types and their strategies
- `references/interpretation_framework.md` - How to interpret institutional flow signals

**Signal Strength Framework:**

**Strong Bullish (Consider buying):**
- Institutional ownership increasing >15% QoQ
- Number of institutions increasing >10%
- Quality long-term investors adding positions
- Low current ownership (<40%) with room to grow
- Accumulation happening across multiple quarters

**Moderate Bullish:**
- Institutional ownership increasing 5-15% QoQ
- Mix of new buyers and sellers, net positive
- Current ownership 40-70%

**Neutral:**
- Minimal change in ownership (<5%)
- Similar number of buyers and sellers
- Stable institutional base

**Moderate Bearish:**
- Institutional ownership decreasing 5-15% QoQ
- More sellers than buyers
- High ownership (>80%) limiting new buyers

**Strong Bearish (Consider selling/avoiding):**
- Institutional ownership decreasing >15% QoQ
- Number of institutions decreasing >10%
- Quality investors exiting positions
- Distribution happening across multiple quarters
- Concentration risk (top holder selling large position)

### Step 5: Portfolio Application

**For new positions:**
1. Run institutional analysis on your stock idea
2. Look for confirmation (institutions also accumulating)
3. If strong bearish signals, reconsider or reduce position size
4. If strong bullish signals, gain confidence in thesis

**For existing holdings:**
1. Quarterly review after 13F filing deadlines
2. Monitor for distribution (early warning system)
3. If institutions are exiting, re-evaluate your thesis
4. Consider trimming if widespread institutional selling

**Screening workflow integration:**
1. Use Value Dividend Screener or other screeners to find candidates
2. Run Institutional Flow Tracker on top candidates
3. Prioritize stocks with institutional accumulation
4. Avoid stocks with institutional distribution

## Output Format

All analysis generates structured markdown reports saved to repository root:

**Filename convention:** `institutional_flow_analysis_<TICKER/THEME>_<DATE>.md`

**Report sections:**
1. Executive Summary (key findings)
2. Institutional Ownership Trend (current vs historical)
3. Top Holders and Changes
4. New Buyers vs Sellers
5. Concentration Analysis
6. Interpretation and Recommendations
7. Data Sources and Timestamp

## Limitations and Caveats

**Data Lag:**
- 13F filings have 45-day reporting delay
- Positions may have changed since filing date
- Use as confirming indicator, not leading signal

**Coverage:**
- Only institutions managing >$100M are required to file
- Excludes individual investors and smaller funds
- International institutions may not file 13F

**Reporting Rules:**
- Only long equity positions reported (no shorts, options, bonds)
- Holdings as of quarter-end snapshot
- Some positions may be confidential (delayed reporting)

**Interpretation:**
- Correlation ≠ causation (stocks can fall despite institutional buying)
- Consider overall market environment and fundamentals
- Combine with technical analysis and other skills

## Advanced Use Cases

**Insider + Institutional Combo:**
- Look for stocks where both insiders AND institutions are buying
- Particularly powerful signal when aligned

**Sector Rotation Detection:**
- Track aggregate institutional flows by sector
- Identify early rotation trends before they appear in price

**Contrarian Plays:**
- Find quality stocks institutions are selling (potential value)
- Requires strong fundamental conviction

**Smart Money Validation:**
- Before major position, check if smart money agrees
- Gain confidence or find overlooked risks
