BOOK REVIEW: ANTIFRAGILE

Takeaway: Buy the book. A must read.

I’ve had many of you ask me for my thoughts on Nassim Taleb’s latest risk management book, Antifragile. So, in the spirit of the main criticism I’d give the book (it’s repetitive), here are some brief notes (< 1000 words = Top 50 highlights):

Summary Thoughts

  1. He doesn’t like academic/unaccountable government policy. Neither do I.
  2. He likes the recent work of Dan Kahnemann (Thinking, Fast and Slow). So do I.
  3. He’s transitioning from market practitioner to philosopher. I wouldn’t do that.

Bottom line: Buy the book. A must read as we continue to narrow the gap between Chaos Theory and Behavioral Finance.
