Why HN recommends it
Mandelbrot argues market risk is fractal and fat-tailed, so extreme crashes like 1987 are more common than standard models assume. Readers with some finance background get a clear challenge to efficient-market thinking.

…unconvinced that debt causes crashes. I personally believe that debt systems aggregate small, localized crashes which happen all the time into large, systemic crashes. A good resource is Mandelbrot's (mis)behavior of markets. It explains a lot of things like how the Pareto principle appears. Reading between the lines, it is easy to see how levy-alpha-stable distributed events can aggregate into bigger levy-alpha-stable…

A great read on an alternative view on the topic of using statistics for finance is The (Mis)Behavior of Markets by Benoit Mandlebrot [1]. It's very well written, basic enough for most to comprehend and first book on finance I read in college (before I went on to major in finance + math). The aforementioned book…

on “Ask HN: What book are you reading?” ↗One book that I have enjoyed is "The (Mis)Behavior of Markets: A Fractal View of Risk, Ruin, and Reward" by Benoit Mandelbrot.

on “Ask HN: Introductory Books on the Stock Market?” ↗I would highly recommend that you read Mandelbrot's books and Nassim Taleb's books. For Mandelbrot, I'd recommend starting with The (Mis)Behavior of Markets. For Taleb, maybe start with The Black Swan.

on “Ask HN: Recommendations for an in-depth book/video series about economics” ↗…Malcolm Gladwell and Daniel Kahneman (author of Thinking, Fast and Slow) both credit Nassim Taleb for a lot of inspiration in their books. Someone mentioned to me that Benoit Mandelbrot (author of (Mis)behavior of Markets) inspired Nassim Taleb for a lot of his thoughts. So there... read Mandelbrot, Gladwell and Kahneman to understand Nassim Taleb.
on “Nassim Nicholas Taleb, Author of Black Swan, on Bitcoin” ↗…Taleb's are more on a philosophical level than What I Learned. - You get more out of Taleb's books if you also read the stuff he references in his bibliographies, from What I Learned..., to Mandelbrot's (Mis)behavior of Markets (understanding Black Swans in terms of fractal randomness gives it a whole new meaning), to Taleb's first book on trading Dynamic Hedging (where he basically explains his extremely technical trading strategy…
