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.
