Why Insider Signals?

Corporate insiders know their companies better than anyone else. When they commit their own money in the open market, especially in meaningful size or in clusters with other executives, it often reflects conviction that is not yet visible in earnings reports, analyst coverage, or headlines. These transactions can reveal shifts in confidence earlier than traditional indicators.

SEC filings are a publicly available information. However, with over 5,000 trade reports filed each day, they are impossible to analyze manually by a human. Our proprietary AI-driven algorithm continuously scans this volume of data and surfaces the activity that actually matters.

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.
