Where Our Data Comes From
Invstify aggregates data from official, publicly available sources. We don't scrape, estimate, or fabricate any data — every number on our platform traces back to an authoritative source.

How Often is Data Updated?
Different data types are updated at different intervals depending on the source and the nature of the data.
How We Detect Cluster Buys
Cluster buys are one of the most closely watched insider trading signals. They occur when multiple insiders independently decide to purchase shares in the same company within a short time window — suggesting coordinated confidence in the stock's prospects.
🔥 Detection Criteria
We automatically scan all incoming Form 4 filings and flag transactions that meet our cluster buy definition.
2+ unique insiders purchasing shares in the same company within a 7-day rolling window⚙️ How It Works
Our system continuously monitors the SEC EDGAR RSS feed. When a new purchase is detected, we check whether another insider bought shares in the same company within the past 7 days.
New Form 4 filed with the SEC
An insider files a Form 4 disclosing a stock purchase.
Invstify ingests the filing
Within 5 minutes, our system picks up the new filing from the SEC EDGAR RSS feed and parses the transaction data.
Cross-reference with recent purchases
We check whether any other insider in the same company has purchased shares within the past 7 days.
Cluster buy flagged
If a match is found, the transactions are flagged with a 🔥 icon and grouped as a cluster buy on the platform.
How We Identify C-Suite Executives
C-suite trades are highlighted with a 👔 icon on Invstify because they often carry more weight than trades by other insiders. Executives in the C-suite have the deepest understanding of a company's operations, financial health, and strategic direction.
We identify C-suite executives by scanning the "Relationship of Reporting Person" field in Form 4 filings for keywords including:
👔 Title Keywords
CEO · CFO · COO · CTO · CMO · President · Chief · Principal Executive · Principal FinancialIf an insider's reported title contains any of these keywords, they are tagged as C-suite and their trades receive the 👔 indicator.
Data Accuracy & Disclaimers
Our data is sourced directly from official SEC filings and established financial APIs. We make every effort to ensure accuracy, but there are some limitations to be aware of:
- Some Form 4 filings contain incomplete data (e.g., missing transaction prices for option exercises or gifts), which may result in trades showing $0 value.
- There is a natural delay between when a trade occurs and when the Form 4 is filed (up to 2 business days by law).
- Stock prices are provided by Finnhub and may differ slightly from other data providers.
- We display data exactly as reported in SEC filings — we do not modify, filter, or adjust data for commercial purposes.
