Insider Trading

Overview

The Insider Trading page tracks all Form 4 filings from the SEC, providing a comprehensive view of buying and selling activity by company officers, directors, and major shareholders (10%+ holders). Irora SEC enriches raw SEC data with cluster detection, conviction scoring, and activity heatmaps to help you identify meaningful trading signals.

The page is organized into five tabs: Transaction Feed, Top Buyers, Top Sellers, Cluster Activity, and By Company. Each tab offers different analytical perspectives on the same underlying insider trading data.

Trading Feed

The Transaction Feed is a chronological log of all insider trades, displaying the insider's name, title, transaction type (buy, sell, exercise, or gift), shares traded, price per share, total value, and ownership change percentage.

Filtering Options

• Search — Filter by insider name, company, or ticker
• Transaction Type — Filter by Buy, Sell, Exercise, or Gift transactions
• Date Range — Select from Today, 7 days, 30 days, 90 days, or 1 year
• Insider Role — Filter by CEO, CFO, Director, VP, or 10% Owner
• Scope — Toggle between all trades or only watchlist companies

The feed supports sortable columns, letting you sort by date, company, insider name, title, transaction type, shares, price, value, or ownership change. Each trade links to the underlying Form 4 filing for full details.

Cluster Analysis

Cluster detection is one of Irora SEC's most powerful insider trading features. A "cluster" occurs when multiple insiders at the same company buy or sell within a short time window. Clusters are often more significant than individual trades because they indicate shared conviction among people with the deepest knowledge of the company.

The Cluster Activity tab displays detected clusters with the following information:

• Company & Ticker — The company where cluster activity was detected
• Cluster Type — Bullish (buying) or Bearish (selling) designation
• Insider Count — Number of unique insiders participating in the cluster
• Total Value — Combined dollar value of all transactions in the cluster
• Time Window — The span of days over which the cluster occurred
• Conviction Score — A computed score (0-100) indicating the strength of the signal

Conviction Scoring

Irora SEC computes a conviction score for each insider cluster on a 0-100 scale. The score is a composite metric based on three factors:

• Insider Count (up to 35 points) — More insiders trading in the same direction increases the score. 4+ insiders earns the maximum.
• Total Value (up to 40 points) — Higher dollar values indicate greater conviction. $10M+ transactions earn the maximum.
• Window Tightness (up to 20 points) — Trades occurring within 3 days or less earn the maximum. Wider windows reduce the score.
• Bullish Bonus (+5 points) — Buying clusters receive a small bonus because insider purchases are generally considered more informative than sales.

Scores are displayed as color-coded progress bars: green for strong signals (70+), amber for moderate signals (40-69), and gray for weak signals (under 40). Labels include "Strong Buy/Sell," "Moderate," and "Weak" designations.

Confidence Index

The stats row at the top of the Insider Trading page provides a quick-glance confidence index across all tracked insider activity:

• Total Trades — The total number of insider transactions in the selected period
• Buys / Sells — Transaction counts broken down by type with percentage of total
• Net Flow — The net dollar value of insider buying minus selling activity
• Active Clusters — The number of currently detected cluster events

An activity heatmap displays 52 weeks of daily insider trading volume, making it easy to spot seasonal patterns and unusual spikes in trading activity.

Analysis Tips

Here are some strategies for getting the most value from insider trading data:

• Focus on open-market purchases — Insider buys are generally more informative than sales. Insiders sell for many reasons (diversification, taxes, estate planning), but they buy for one reason: they believe the stock will go up.
• Watch C-suite activity — Trades by the CEO, CFO, and COO tend to carry more weight than trades by directors or VPs, as they have the most direct knowledge of the company's operations.
• Combine with filing analysis — When you spot unusual insider activity, check the company's recent filings for context. A cluster of insider buys after an 8-K disclosure might indicate insiders believe the market has overreacted.
• Use the "By Company" tab — This aggregated view shows net insider activity per company, making it easy to identify which companies have the strongest insider conviction.
