Criminal Insider Trading Charges (15 USC 78j(b))

Criminal insider trading charges under 15 USC 78j(b) and SEC Rule 10b-5 represent the most serious enforcement action available to the Department of Justice and Securities and Exchange Commission. Unlike civil enforcement, criminal prosecution requires proof beyond a reasonable doubt that the defendant knowingly and intentionally traded on material nonpublic information obtained through a breach of fiduciary duty (classical theory) or misappropriation theory. Conviction carries sentences up to 20 years imprisonment and fines exceeding USD 5 million, with mandatory disgorgement of profits and civil penalties up to three times the trading gains.

Quantitative insider trading detection platforms must flag trading patterns consistent with criminal liability indicators, including abnormal volume concentrations, timing clustering relative to material announcements, profit realization immediately pre-announcement, and cross-account correlation with identified tippees or misappropriators. The SEC's investigation process typically involves subpoenas of trading records, communications analysis (email, chat, phone records), and forensic reconstruction of information flow timing to establish the causal link between possession of MNPI and trading execution.
