The SEC operates sophisticated surveillance systems that process approximately one billion trade records daily, with timestamps accurate to the microsecond. These systems cross-reference trades against corporate announcements, earnings reports, and merger filings.

How the SEC Catches Insider Trading

1. Pattern Recognition (ARTEMIS)

ARTEMIS identifies correlated clusters of trading activity across multiple accounts that align with non-public corporate events. Small trades cannot escape detection.

2. Timing Analysis (MIDAS)

MIDAS ingests every order from every exchange and dark pool, tracking precisely when transactions occur. Trading within five minutes of a material event triggers detection.

3. Network Analysis (Blue Sheets)

Blue sheets data links every trade to brokerage accounts and individuals. Using a friend’s account provides no protection.

4. Communication Subpoenas

SEC investigations extend to emails, text messages, and chat logs. Subpoenas target employer email servers, phone records, and messaging applications.

Why the Government Always Wins

  • They Control the Timeline: Investigations typically span 18 months before subjects receive notice.
  • They Have the Data: The SEC establishes guilt through pattern analysis, not intent.
  • They Have the Leverage: The SEC possesses authority to seize assets and impose lifetime industry bans.
  • Cooperating Witnesses: Whoever cooperates first typically receives the most favorable treatment.

The “Everyone Does It” Myth

Using friends’ brokerage accounts, encrypted messaging, and delayed trades all fail because the surveillance infrastructure is designed to detect exactly these patterns.

Common Mistakes to Avoid

Actually Stay Silent

Most people know they have the right to remain silent but still talk to police. Anything you say can and will be used against you. Politely decline to answer questions until your attorney is present.

Bail Conditions Are Enforceable

Violating bail conditions, even minor ones, can result in immediate re-arrest and make it much harder to obtain bail again. Follow every condition to the letter.
