之所以称之为Technical Log,我是希望把这部分内容自己在学术方面的回顾参考。也就是说记录自己在一段时间内的学术成长,或者说对技术方面的认识成长的经历。
今天算是开始~

数学定义的完全市场是没有套利的机会的,根据鞅停时定理(or whatever),没有人能够创造一种策略可以获得超额收益。或者说,获得超额收益是小概率事件。
但是生活中有很多的例子告诉我们,市场是不完全的,如果数学模型真的是对的话,那么这些小概率事件都发生的未免太多了一些。总结来说,作为一个金融数学家,我们不应该相信存在套利的机会。而作为一个金融家,我们永远应该坚信存在某种规则可以获得超额收益。当然这种规则不是那么简单的,否则为什么你知道而别人不知道呢?
复杂的东西不直观,而直观的东西并不一定能够赚钱,感觉是太玄的东西。dig the gold. if we really want more gold than others, we might have to dig deeper and deeper. but digging deeper don't mean more gold. wish you good luck! everything is so, isn't it?
