Name: SEC Insider Buying — Form 4 Feed
Creator: Capitol Whale

Live SEC Form 4 filings — corporate insiders buying their own stock, updated in near-real-time from EDGAR.

as of 23:43:04 UTC

Insider buying is the cleanest bullish signal in equities research: corporate officers, directors, and 10%+ owners spending their own money to buy shares in the open market. Under Section 16 of the Securities Exchange Act, every one of those trades gets reported to the SEC on Form 4 within two business days.

This feed surfaces every Form 4 filed on EDGAR, filtered to open-market purchases (transaction code P), and enriched with cluster-buy detection so you can spot when multiple insiders at the same company are buying inside the same 30-day window — historically the strongest long-term signal you can pull from the filings.

How to read Form 4

Transaction code P — open-market purchase. This is what "insider buying" refers to.
Transaction code S — open-market sale. Check the 10b5-1 checkbox first.
Transaction code A — grant, award, or acquisition (usually an RSU or option grant). Not a discretionary purchase.
Transaction code F — payment of tax liability by withholding shares. Not selling pressure.
Cluster buy — 3+ insiders buying in the same 30-day window. This is the setup with the strongest historical edge.

Frequently asked questions

Where do these Form 4 filings come from?

Every Form 4 shown here is pulled directly from the SEC's EDGAR system within minutes of the filing being accepted. The SEC requires corporate insiders (officers, directors, 10%+ owners) to file Form 4 within two business days of a covered transaction.

What is insider buying and why does it matter?

Insider buying is when a company's own executives or directors purchase shares in the open market with their own money. Because insiders have unique visibility into the business, sustained cluster buying at multiple insiders in the same window is one of the more reliable long-term bullish signals in equities research.

Is insider buying always bullish?

No. Single small purchases can be cosmetic. The signal strength grows when multiple insiders buy in the same 30-day window (cluster buying), when purchases are large relative to the insider's existing stake, and when they happen after a drawdown rather than at all-time highs.

How do you handle 10b5-1 plan sales?

Sales scheduled under a Rule 10b5-1 trading plan are flagged with the checkbox reported on Form 4. We surface the flag on every sale row so you can filter out pre-scheduled dispositions from discretionary selling.

What it is. Insider Buying: Insider Buying is a Capitol Whale market-data tracker covering insider buying in real time. We aggregate SEC filings, exchange feeds, on-chain data, and Congressional disclosures to surface positioning, flow, and smart-money signals in one place.

Why it matters. Insider Buying matters because retail traders now compete against algorithms and disclosed institutional flow. Tracking insider buying on Capitol Whale gives you the same public-filing edge that professional desks build in-house — without the six-figure Bloomberg terminal.

What moves it. Insider Buying responds to broad market regime (risk-on vs risk-off), sector-specific catalysts, macro liquidity shifts, and the specific institutional flow this tracker captures. Cross-reference with the related trackers below for a fuller picture.

Common mistakes. Reading a single data point in isolation. Ignoring the base rate. Confusing correlation with causation. Failing to check the "last updated" timestamp before acting on stale numbers.
