Strategic Signal Filtering

Our screener allows you to cut through the noise of routine stock grants and small trades. By focusing on high-value transactions from C-suite executives (CEO/CFO), you can identify where the "Smart Money" is being deployed with maximum conviction.

Investing Without Illusions

Insider data is not a magic wand, but it is the most honest indicator available. While insiders sell for many reasons (taxes, personal needs), they generally buy for only one: they believe the stock price is undervalued. We provide the tools to track these skin-in-the-game moves.

UNDERSTANDING THE DATA

FILING DATE: The date and time when the transaction was reported to the SEC. This is when the public first receives the information.

TRADE DATE: The actual day the insider executed the purchase or sale in the market.

INDUSTRY: The specific market sector the company operates in. Useful for identifying broader institutional capital flows across sectors.

OWNED AFTER: The total number of shares held by the insider following the transaction. This highlights the insider's remaining conviction in the company.

CHANGE %: The percentage increase or decrease of the insider's total position. Large percentage changes often carry more weight than the dollar amount alone.

TRADE TYPES DEFINITIONS

BUY: An open market purchase. Typically indicates an insider's belief that the stock is undervalued or poised for growth.

SELL: An open market sale. While often used for diversification or liquidity, large or unexpected sales can be a warning signal.

OPT+S (OPTION EXERCISE & SALE): This occurs when an insider exercises their stock options and sells them immediately. Often part of a structured compensation plan.
