Every insider stock transaction (non-derivative table) reported to the SEC on Form 4 and 4/A over the latest 5 EDGAR business days (filed 2026-09-17 to 2026-09-23; a few late filings report older trades): officers, directors and 10% owners buying, selling, receiving grants, exercising options, gifting shares and more, across all SEC-reporting issuers. Cleaned into one flat table with ticker, insider role, dollar value and a cluster-buy flag (2 or more insiders of the same company buying on the open market within 7 days).

This build: 4,191 transactions from 2,241 Form 4 filings, including 2,020 open-market trades (382 purchases), with cluster buys at 34 issuers. See meta.json for the exact build time and counts.

Use it

from datasets import load_dataset
df = load_dataset("CyberMax-tools/sec-form4-insider-transactions", split="train").to_pandas()
buys = df[(df.transaction_code == "P") & (df.acquired_disposed == "A")]
print(buys.sort_values("total_value_usd", ascending=False)[["ticker", "owner_name", "owner_role", "total_value_usd"]].head(20))
print(df[df.cluster_buy][["ticker", "issuer_name", "cluster_insider_count"]].drop_duplicates())

Open-market only: df[df.is_open_market] (codes P and S). Most other codes (A, M, F, G) are compensation or tax mechanics rather than a view on the stock.
