Insider Trading Tracker (SentiSense)

Track what company insiders are doing with their own stock. This skill reads SEC Form 4 filings, the disclosures that officers, directors, and 10%+ shareholders must file within two business days of any transaction, through the read-only SentiSense API: the insider tape for a single stock, market-wide insider buying and selling, and cluster buy signals where three or more insiders bought the same name. It completes the smart-money triangle with politicians-stock-tracker (congressional trades) and institutional-13f-tracker (fund holdings).

Read-only educational data interface. Output is informational context, never a personalized buy or sell recommendation.

When to Use

Reach for this skill when the question is about insider activity:

• "Any insider buying in $NVDA?" or "show me the Form 4 filings for this stock"
• "Which stocks are insiders buying right now?" (market-wide activity)
• "Are there cluster buys?" (3+ distinct insiders buying the same stock, a pattern long studied in academic research)
• "Is the CEO selling?" and "was that sale pre-planned or discretionary?" (10b5-1 detection)
• As the third leg of a convergence check: insider buys lining up with congressional purchases (politicians-stock-tracker) or institutional accumulation (institutional-13f-tracker) on the same ticker.

Do not use it for order entry, portfolio management, or personalized advice. It has no write, trading, or wallet surface; every endpoint is a GET.
