About Us — WhaleSentiment Research

WhaleSentiment Research is an independent financial data journalism project. Our mission is simple: to make insider trading data — public by law but notoriously hard to interpret — accessible and understandable to every investor.

🐋 What We Do

We monitor SEC (Securities and Exchange Commission) filings in real time. When an executive, board member, or major shareholder buys or sells shares of their own company, we know about it — and we make it available in a clear, analyzable format.

Our focus is on Form 4 filings (completed insider transactions), Form 144 filings (advance notice of intent to sell), and XBRL financial data that helps contextualize insider activity.

            Our Principles
            Total transparency — every data point is traceable to its original SEC source filing
No opinions disguised as data — we keep facts and analysis strictly separate
Daily updates — data is collected and published every single day
Free access — information that once required a Bloomberg terminal is now available to everyone at no cost

        

📊 How It Works

Our automated system:

Collects Form 4 filings (completed insider transactions) from the SEC
Analyzes Form 144 filings (intent-to-sell notices) — a leading indicator that very few platforms track
Integrates XBRL financial data to provide context for insider transactions
Computes the Insider Sentiment Score — a proprietary indicator that synthesizes insider behavior
Publishes everything with daily updates in both English and Italian
