I don't have special insights. What I'm going to say is obvious. Main cause of Bill Hwang's blow-up is too much leverage. What surprised me about the leverage is why did multiple prime brokers extend him so much leverage that all of them died together? Shouldn't there be some established risk management process to prevent such things from happening in financial institutions? I would like to hear from other elite-traders on what are some other risk management mistakes that were made in this blow-up.
