Insider & Congressional Trading

Corporate insiders — executives, directors, and major shareholders — are required by law to report their stock transactions to the SEC. Members of Congress face similar disclosure requirements under the STOCK Act. These filings are public. When a CEO buys a significant amount of their own company's stock on the open market, it's one of the most credible signals in finance. GenHedge tracks and surfaces these filings daily.

What it covers

SEC Form 4 filings (insider buy/sell transactions at public companies), congressional STOCK Act disclosures (trades by sitting U.S. senators and representatives), and cluster analysis — when multiple insiders at the same company buy simultaneously. The signal focuses on open-market purchases, which are voluntary and carry real conviction. Option exercises and gifts are tracked but weighted differently.

What moves it

Insider buying matters because executives have the best information about their own business. An open-market purchase — where a CEO uses personal cash to buy shares at market price — signals that management believes the stock is undervalued. Cluster buying (multiple insiders buying within the same window) amplifies the signal. Congressional trades attract attention because lawmakers may have access to policy information before it's public. The signal is not about following trades blindly — it's about understanding the information context behind them.

Key terms

Form 4

The SEC disclosure form that corporate insiders must file within two business days of a transaction. It reveals who bought or sold, how much, and at what price.

Open-Market Purchase

When an insider buys shares on the stock exchange using personal funds — not through options or compensation grants. This is the highest-conviction signal because it's entirely voluntary.

STOCK Act

The Stop Trading on Congressional Knowledge Act (2012). Requires U.S. senators and representatives to publicly disclose stock trades within 45 days. Violations carry fines.

Cluster Buying

When two or more insiders at the same company make open-market purchases within a short time window. Historically one of the strongest predictors of positive price action.

Section 16 Insider

Officers, directors, and shareholders owning more than 10% of a company. These individuals are required to file with the SEC and face restrictions on short-swing profits.

In the newsletter

GenHedge monitors SEC Form 4 filings and congressional disclosures daily. The insider signal surfaces cluster buying events, unusual purchase sizes relative to historical patterns, and congressional trades in sectors where policy decisions are pending. It's pattern recognition from public data — not a buy signal.
