Marc Cohodes has earned a living and a reputation betting against companies he suspects committing fraud. His high-profile take-downs include Insys Therapeutics founder John Kapoor—the orchestrator of a scheme to bribe doctors to prescribe a fentanyl-based pain medication that caused the deaths of 7,000 people. 

During our earthy and entertaining chat, Cohodes' describes how his shorting career began when he bet against a pinball machine manufacturer at the dawn of the video game age. He explains the rationale behind some of his long positions and maintains that it's not what you've done but what you do next that counts.
