Insider Radar
Scan SEC Form 4 insider trades and 13F ownership moves for a ticker or a watchlist using the AlphaAI MCP. Use when the user asks about "insider buying", "insider selling", "Form 4 activity", "who's buying <ticker>", "institutional ownership changes", or wants an insider-activity sweep.

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
- Single ticker. Call
alphai_insider_news(ticker=""). If the user
wants only the strongest signal, raise the floor with min_relevance=8.
- Watchlist. Call
alphai_insider_news(ticker=...)once per name. If the
user gave none, call alphai_insider_news() unfiltered for the broad tape.
- Time-box on request. For "this week" / "since earnings", pass
from_date (ISO, UTC). Paginate with cursor only if they ask for more.
- 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.
