Political Capital Tracker — Congress + Institutional 13F Convergence Signal

Find stocks where Congress members AND Wall Street are buying simultaneously.

This actor combines two of the most powerful public data sources in finance:

1. Congressional trades (STOCK Act disclosures via House Stock Watcher)
2. SEC 13F institutional holdings (largest hedge funds and asset managers)

When a politician buys a stock and a top-tier institution is increasing its position in the same quarter — that's a convergence signal. Research shows congressional trading outperforms the market; combining it with institutional confirmation dramatically reduces noise.

No API key required. Completely free data sources.

What This Actor Does

1. Downloads all House congressional trade disclosures (public S3 dataset, updated daily)
2. Filters to recent purchases within your lookback window
3. Groups by ticker — finds stocks with multiple politicians buying
4. Fetches the latest SEC 13F-HR filings for major institutional funds via EDGAR
5. Cross-references: which tickers appear in both politician buys AND institutional increases?
6. Outputs ranked convergence signals with full politician + fund attribution

Convergence Signal Logic

For each ticker T with >= N politician buys in the last X days:
  - Check if any major 13F filer increased position in T (new or increased QoQ)
  - convergence_score = politician_buy_count × (1 + institutional_increasing_count)
  - Flag as "convergence_signal" if any institution is bullish, else "politician_buy"

Higher convergence scores = stronger signal (more politicians + more institutions).

Use Cases

• Quantitative trading signals — Add congressional + institutional confirmation layer to stock screeners
• Political alpha research — Study the "Congress premium" with institutional validation
• Sentiment analysis — Track when political and financial elites align on same bets
• Risk management — Avoid stocks where politicians are selling while institutions exit

Data Sources

Source	URL	Update Frequency	Auth
House Stock Watcher	S3 public dataset	Daily	None
SEC EDGAR 13F-HR	data.sec.gov	Quarterly	None
OpenFIGI (CUSIP→Ticker)	api.openfigi.com	Real-time	None

Important: Congressional trades are disclosed within 30–45 days of the transaction under the STOCK Act. 13F filings are submitted within 45 days of quarter end. This is backward-looking data — not real-time.

---

Limitations

• House only for congressional data (Senate STOCK Act disclosures are separate and less structured; future version may add Senate via efts.sec.gov)
• 45-day lag on 13F filings — institutional positions reflect quarter-end, not current
• CUSIP → ticker mapping relies on OpenFIGI free tier (may miss some exotic securities)
• Fund name matching uses EDGAR full-text search — obscure fund names may not resolve
