Frequently asked questions

Is tracking insider trades legal?

Absolutely. All insider trades analyzed by InsiderBrief come from public SEC Form 4 filings. Corporate insiders are legally required to disclose their trades, and these filings are publicly available through EDGAR. What's illegal is trading on material non-public information — reading publicly filed disclosures is not.

Is InsiderBrief investment advice?

No. InsiderBrief provides analysis and commentary on publicly available SEC filings for informational and educational purposes only. We do not recommend buying or selling any security. Always do your own research and consult a qualified financial advisor before making investment decisions.

How is InsiderScore™ calculated?

InsiderScore is a proprietary 0-100 scoring framework designed by a CFA charterholder. It evaluates seven factors: transaction type, insider seniority, dollar size, size relative to holdings, cluster signals (multiple insiders buying), timing context (post-earnings, near 52-week lows), and contrarian signals (buying during market declines). Only trades scoring 60+ make it into the daily brief.

When are briefs delivered?

Daily briefs are delivered to paid subscribers (Signal and Pro tiers) by 6:30 AM ET every weekday morning, covering the previous day's insider trading activity. Free subscribers receive a weekly digest every Sunday morning summarizing the top 5 trades of the week.

What's the difference between Signal and Pro?

Signal ($19/mo) gives you the daily morning brief with full analysis and a 30-day web archive. Pro ($39/mo) adds the full searchable trade database, custom watchlist alerts, sector filters, API access, and unlimited archive access.

Can I cancel anytime?

Yes. All subscriptions are month-to-month with no commitment. Cancel anytime from your dashboard and you'll retain access through the end of your billing period.
