# Insider radar Surface ownership-change signal: **SEC Form 4** trades (officers, directors, 10% owners trading their own stock) and **13F** moves (funds and foundations adjusting stakes). AlphaAI templates each filing into a relevance-scored news row, so the read-across is already done. ## Steps 1. **Single ticker.** Call `alphai_insider_news(ticker="<SYM>")`. If the user wants only the strongest signal, raise the floor with `min_relevance=8`. 2. **Watchlist.** Call `alphai_insider_news(ticker=...)` once per name. If the user gave none, call `alphai_insider_news()` unfiltered for the broad tape. 3. **Time-box on request.** For "this week" / "since earnings", pass `from_date` (ISO, UTC). Paginate with `cursor` only if they ask for more. 4. **Distinguish buys from sells.** Open-market *purchases* by insiders are the higher-signal event; routine 10b5-1 scheduled sales and option-exercise sales are noise more often than not. Call that out — don't treat every sale as bearish. ## Output - **Notable buys** — insider purchases first: ticker · who/role · size if given · relevance. These are what most users actually want. - **Notable sells** — flag whether each looks like a discretionary sale vs a scheduled/10b5-1 or option-related sale, where the feed says. - **Institutional (13F)** — any fund stake increases/trims worth a mention. - **Read** — one line: is the cluster leaning accumulation or distribution, or is it just routine? ## Guardrails - An insider sale is not automatically bearish (taxes, diversification, scheduled plans). Say what the filing shows; don't over-read it. - One filing can span several tranches sharing a row — report the *event*, not a count of line items. - Lead with `relevance_score`; "no notable insider activity in the window" is a valid, useful answer. - News, not advice.
