Why Insider Signals?

Corporate insiders have a deeper understanding of their companies than outside investors. When they buy or sell shares in the open market, especially in meaningful size or alongside other executives, their actions can provide valuable insight into how they view the company's future. These transactions may reveal shifts in confidence before they become apparent in earnings reports, analyst coverage, or headlines.

Insider trading filings are publicly available through the SEC. However, with more than 5,000 filings submitted each day, identifying meaningful activity is impractical without AI automation. Altymo continuously analyzes this stream of data to detect significant insider buying and selling patterns, including cluster purchases, trend reversals, trend accelerations, and other unusual changes in insider behavior.

Signal analytics

Signal Intelligence

Unlike traditional insider tracking tools that simply display individual transactions, Altymo analyzes each filing and historical insider activity to identify trends and produce actionable buy and sell signals.

With Altymo, you'll be able to see the following data for each signal:

  • A visual history of insider activity
  • AI-generated explanation of what happened
  • The filings behind the signal
  • Individual insider transactions
  • Participating insiders
  • Ownership stake changes
  • Statistical context and trend data

How Does It Work

Altymo uses a multi-step algorithm that continuously monitors thousands of SEC filings and produces actionable intelligence.

Ingest SEC filings

Step 1: Ingest SEC Filings

New SEC filings across the entire market are continuously imported and processed as they are submitted throughout the trading day.

Clean & normalize data

Step 2: Clean and Normalize Data

SEC filings often contain inconsistent company names, tickers, dates, amendments that must be standardized before analysis.

Analyze transactions

Step 3: Analyze the Meaning of Each Transaction

Each transaction is evaluated to determine whether it reflects meaningful insider activity or routine filing noise, such as stock option exercises or financing participation.

Detect unusual trading patterns

Step 4: Detect Unusual Insider Trading Patterns

The system analyzes insider activity across time to identify unusual buying, selling, accelerations, reversals, and emerging trends.

Recompute signals

Step 5: Recompute Signals as New Data Arrives

Financial markets are constantly evolving. Our system can upgrade, downgrade, or modify a signal as new information becomes available.
