History

Historical Context

In October 2009 the SEC arrested hedge-fund founder Raj Rajaratnam, charging him with insider trading that yielded over $60 million in illicit profits and led to a $92.8 million civil penalty—the largest ever against an individual. The case marked the start of a post-crisis enforcement surge, exemplified by the 2010 Operation Broken Trust crackdown that targeted hundreds of fraud schemes and signaled expanding regulator scrutiny of emerging digital-asset markets.
