He was quoted in a interview with CNBC "Fast Money" as endorsing Insider Trading.
Insider trading qua insider trading is in fact ethically speaking a non-crime. It is not immoral to act on information that others don't have access to when it benefits you financially.
What might be immoral on the other hand is doing it in particular ways under certain circumstances, provoking some of these circumstances, and especially if it violates contractual obligations.
