black-edge

Sheelah Kolhatkar's Black Edge — an executable toolkit that extracts investigative lessons from the SAC Capital story: how insider trading works, how aggressive hedge fund culture blurs ethical lines, how regulators build cases, and how to recognize when the pursuit of "edge" crosses into illegality. Covers 5 use cases: ① Insider Trading Awareness — recognize the patterns of illegal information flow ("What is insider trading" "How do people get away with it") ② Hedge Fund Culture Analysis — understand how aggressive performance culture pushes ethical boundaries ("My fund pushes for too much information" "How do I know if something is crossing the line") ③ Investigation Understanding — how the FBI and SEC build insider trading cases ("How do they catch insider traders" "What is a cooperating witness") ④ Ethics & Compliance — navigate the gray zone between aggressive research and illegal activity ("Where is the line between research and inside info" "How to stay compliant") ⑤ Whistleblower & Cooperator Dynamics — understand flipping and cooperation in financial investigations ("Should I cooperate with a federal investigation" "How to report financial misconduct") Trigger when users say: "Insider trading" "SAC Capital" "Steven Cohen" "Black Edge" "How do they catch insider traders" "Hedge fund secrets" "SEC investigation" "Cooperating witness" "Expert networks" "What is material non-public information" "How to stay compliant in finance" "Financial fraud detection" or mention: Sheelah Kolhatkar / Black Edge / SAC Capital / Steven Cohen / insider trading / SEC / FBI / MNPI / hedge fund / edge / cooperating witness / wiretaps / expert networks / compliance / insider trading cases / regulatory investigation.
