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.
之前有书评说目前分形研究尚无严格的理论。也许严格的理论是存在的,不过很可能和人类固有的认知事物的方式相悖所以从来没被想到过,而对目前的机器学习来说所有的历史波动数据又太少。索罗斯说每次他感到情况不对都会背痛,这使我猜想顶尖的交易员可能属于少数天生有这种下意...
评分《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...
评分本书是EmpricalFinance的老师推荐阅读书籍,但之前也有所耳闻,市面上评价也很高,所以特地买来阅读。 但很难想象豆瓣上没有人评论这本书,希望有更多的人能看到这本书,因为它能颠覆你对金融的所有想象和理解,尤其是学金融的人。 在作者眼中,过去我们所了解的传统和现代金...
评分曼德勃罗对金融市场的看法是符合幂律分布,关键的肥尾是长期依赖性(或称相关性)的结果,可是这个关键的长期依赖性的原理是什么,没有解释。实际上对于肥尾的产生有很多解释,索罗斯的反身性理论,自组织理论的临界。 第一章 风险、破产和收益 五个规则: 1、市场是有风险的...
评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...
这本书他妈怎么会有人给4颗星以下? 脑子坏了吗?
评分真心看不惯那些自以为是的嘴脸,说着boring,浪费时间的读者,站在巨人的肩上嘲笑巨人合适吗?
评分True iconoclast!但他建立的理论还不够完善,还较难以直接应用。
评分跨学科
评分挺有意思的一本书。所有的model都是有问题的,那一个能给出准确结果的差model和一个不能给出准确结果的好model哪个更有用些? #这个世界上唯一不变的就是变化本身
