Frequently Asked Questions

Form 13F is a quarterly report filed by institutional investment managers with over $100 million in qualifying assets. It reveals their long U.S. equity holdings, giving the public a delayed but valuable view of what "smart money" owns.

Form 4 is a document that must be filed whenever corporate insiders—such as directors, officers, or beneficial owners of more than 10% of a company's stock—buy or sell shares of their own company. Unlike 13Fs, these reflect personal transactions by the people running the company.

• 13F (Quarterly): Due 45 days after the calendar quarter ends (e.g., mid-May for Q1).
• Form 4 (Real-time): Generally due within 2 business days following the transaction. This makes Insider data much more timely than institutional data.

• Exchange-traded equities (Stocks, ETFs)
• Equity options (CALL / PUT)
• Convertible debt (PRN)

We primarily track open market transactions which are most relevant for sentiment:

• P (Purchase): Buying securities on the open market. Often seen as a bullish signal.
• S (Sale): Selling securities on the open market.
• A/D (Grant/Disposition): Shares awarded as compensation or withheld for taxes (usually less indicative of sentiment).
• M (Exercise): Exercising options to convert them into shares.

• PRN: Principal amount on convertible debt securities.
• CALL: A call option position (betting the price will rise).
• PUT: A put option position (betting the price will fall).

We poll the SEC EDGAR system every few minutes.

• Insider Filings (Form 4): Appear on 13Radar almost instantly after SEC release (daily).
• Institutional Filings (13F): Processed and live typically within 2-5 minutes of release (quarterly).

We employ a multi-layered verification process:

• SEC Cross-Check: Every data point is validated against the original SEC source document.
• Historical Corrections: We automatically detect and fix common filing errors, such as incorrect CUSIPs or values not reported in thousands.
• Split Adjustments: We retroactively adjust historical share counts for stock splits to ensure trend lines are accurate.

The Guru List is a curated directory of the world's top investors (e.g., Warren Buffett, Ray Dalio). It allows you to track their 13F portfolios, see their latest moves, and analyze their historical performance.

This tool flips the perspective from "who" to "what". Instead of showing noisy data from thousands of funds, it focuses specifically on our curated list of "Gurus".

When you search for a stock (e.g., AAPL), you can see exactly which legendary investors own, are buying, or are selling that specific asset. This helps you validate if a stock meets the standards of top-tier capital allocators.

This is a real-time monitoring tool based on Form 4 filings. Unlike quarterly 13F reports, this shows immediate transactions by corporate insiders (CEOs, CFOs, Directors).

• Real-time Signals: Updates almost instantly after SEC filing.
• True Conviction: We distinguish between "Open Market Purchases" (buying with their own money) and stock grants, helping you spot genuine insider confidence.

This feature aggregates data to highlight stocks that are most widely held by our list of top investors. It helps identify high-conviction ideas where multiple "smart money" managers independently agree on the same asset.
