Taleb has never revealed the details of his investment portfolio. For someone who screams "I don't care - show me the returns!" it's interesting that he cannot prove that his "black swan" strategy has ever been actionable for his own or anyone's portfolio, how to use his theories to make significant money vs. normal strategies, and any proof that his hedge fund made any money during the dot-com crash which you would figure would be the prime time to make money given his public persona.
Taleb got profiled in the New Yorker, his Black Swan book became popular, and he has rode that and Twitter ever since. I highly recommend people see him for what he is - a public figure that is a bullshitter like anyone else - at least until he shows proof that he is some sort of investor oracle. He has actively sued people who revealed how much money his prior fund lost, as those documents are floating around but he attacks anyone who publicly reveals them.
