Timely SEC Insider Filing Alerts
Get high-signal SEC insider trading alerts on newly public Form 4 filings. Track corporate Form 4 filings, Congressional stock trades, and institutional 13F holdings in one clean dashboard. Not investment advice.
Turn public filings into organized SEC insider trading alerts
Every day, corporate officers, directors, and large shareholders file thousands of disclosures with the U.S. Securities and Exchange Commission. Most are routine — stock grants, automatic sales, or portfolio rebalancing — and contain little predictive value. DisclosureSignals spots the exceptions and delivers clean, near-real-time alerts after filings become public.
Form 4 Filings
Track insider buys and sales reported on Form 4, which insiders generally must file within two business days of the transaction. We flag open-market purchases, cluster buying, and unusually large trades.

Why DisclosureSignals is different
Not every insider purchase is bullish, and not every sale is bearish. Our heuristic scoring model filters out routine compensation and ranks trades by factors like transaction size, cluster buying, and whether the purchase was discretionary. Scores describe transaction characteristics — they are not predictions of future performance.
