From the inventor of fractal geometry, a revolutionary new theory that overturns our understanding of how markets work.
Benoit B. Mandelbrot, one of the century's most influential mathematicians, is world-famous for making mathematical sense of a fact everybody knows but that geometers from Euclid on down had never assimilated: Clouds are not round, mountains are not cones, coastlines are not smooth. To these classic lines we can now add another example: Markets are not the safe bet your broker may claim. In his first book for a general audience, Mandelbrot, with co-author Richard L. Hudson, shows how the dominant way of thinking about the behavior of markets--a set of mathematical assumptions a century old and still learned by every MBA and financier in the world--simply does not work.
As he did for the physical world in his classic The Fractal Geometry of Nature, Mandelbrot here uses fractal geometry to propose a new, more accurate way of describing market behavior. The complex gyrations of IBM's stock price and the dollar-euro exchange rate can now be reduced to straightforward formulae that yield a far better model of how risky they are. With his fractal tools, Mandelbrot has gotten to the bottom of how financial markets really work, and in doing so, he describes the volatile, dangerous (and strangely beautiful) properties that financial experts have never before accounted for. The result is no less than the foundation for a new science of finance.
《市场的(错误)行为:风险、破产与收益的分形观点》是分形几何学创始人贝努瓦•曼德尔布罗特写的本关于金融市场的书,看完后,我基本不知道他在说什么,我只明白了他在书的前三分之一是在批评现代金融理论,包括马可维茨的投资组合理论,夏普的CAPM,布莱克思科尔的期...
評分之前读过很多批评“市场有效性假说”这一现代金融“神学”的文章。这本书更是把有关理论中的荒谬之处揭示于众,特别是关于正态分布的假定,以及价格波动随机性(独立性)的假设。作者是较早指出厚尾问题的人之一。时至今日,厚尾问题已广为人知,但即便如此,很多人仍在不假思...
評分《市场的(错误)行为》是一本书能引发思考,读了虽未必对金融交易有什么实际帮助,但却能从理念层面对金融市场有一个全新认识。要取得盈利你首先要有耐心,因为大多数时候市场都是波澜不惊的,同时你也要有惊人的洞察力,因为决定胜负关键就在那罕见几次超级波动中。 幂...
評分現在金融界使用很多數學、物理的學生,為甚麼?因為金融界使用許多模型,預測股市走勢,而那些模型假設股票交易和布朗運動、熱傳導等物理學現象相近。這些模型包括Black-Scholes、Capital Asset Pricing Model (CAPM) 等。 但是分形學的創立人、數學家Benoit Mandelbrot毫不猶...
評分一個分形學者眼中的金融市場。
评分分形幾何的觀點,對於市場來說非常重要。至少對於隨機理論是一種強有力的打擊。不過,也不是什麼趨勢技術分析的問題。很多問題,教授談論還是比較升入的。值得看看,假如你有一些分形幾何的基礎。

评分老生常談,boring
评分市場行為的分形觀點,隻是感覺還缺點什麼。。。雖然圖形上分形確實更容易解釋,但生成過程上感覺解釋並不理想,或許馬爾可夫過程或者貝葉斯可能更適閤描述此類過程(盡管作者不太贊同類似觀點),又或者是因為對分形的理解還是太過錶麵瞭。。。
