InsiderAlpha tracks SEC Form 4 insider transactions in real-time and turns them into daily stock buy signals. Free company and insider profile pages, 10-K / 10-Q / 8-K coverage, AI-scored trade ideas.
InsiderAlpha ingests every SEC Form 4 (corporate insider transactions), Form 144 (planned restricted-stock sales), and Form 8-K (material events) filing the moment it hits EDGAR. We deduplicate amendment chains, parse the underlying XBRL, classify each transaction by code (P open-market buy, S sell, M option exercise, A award, G gift, F tax withholding), and surface the ones that historically precede price moves — cluster buys, first-time officer purchases, and contrarian insider buying during drawdowns. Each filing is checked for Rule 10b5-1 trading-plan footnotes so you can separate discretionary trades from pre-scheduled ones.

Companies with the highest Form 4 filing volume in the last two weeks. High filing counts often signal an open trading window after an earnings release, an option-grant date, or a 10b5-1 plan kicking in.
Tickers our visitors look up most often when researching insider activity. Each link goes to the full /company/{ticker} profile with insider transaction history, recent SEC filings, and a Form 4 / 144 / 8-K timeline.
Plain-English guides to corporate insider reporting and the signals worth acting on:
Officer and director purchases are one of the few signals where the insider has both better information than the public and a legal obligation to disclose within two business days. We turn that disclosure stream into a daily, scored buy list: every filing is checked against the company’s technicals (RSI, ATR, MA-50), liquidity (50-day average volume), and historical insider track record. Premium tiers add AI commentary, watchlist alerts, and a backtested daily plan; company and insider profile pages are free and indexable.
