> Yes, the SEC definitely follows up on this

Yes, and they're quite adept at it even if you don't think you're leaving a trace. For example: https://www.sec.gov/news/press-release/2014-55

Interesting how the middleman got off without punishment. Shows how narrow insider trading can get, which speaks the the programmer tendency to assume law is code. Rather law is interpreted and in this case only two of the three parties fell under the SEC enforcement. That neither is going to jail is also notable, SEC can take money and burn a career but stealing from the market is lots safer than selling drugs.

Well, for insider trading, it isn't prohibited by law. It's entirely precedent.

That account sounds like at least one of the 3 provided a detailed description of what happened. The SEC weren't listening into the initial conversations they had - presumably they got wind of the trading and then managed to get enough leverage on one of them to make them talk. If they didn't talk, I wonder what level of evidence the SEC would have.

I got a call from them after a cousin I’ve never met traded the stock of the company I was working at. Anybody who works at a public company sees insider information every day. Anybody who thinks they want to profit of it, especially if they think doing so would be easy, can expect a run in with the SEC.
