According to the metric, the beta or volatility of the market is 1. If the beta of a stock is greater than 1, it is considered more volatile than the market. If the beta of the stock is less than 1, it is less volatile than the market. What is an alpha stock? An alpha stock ...

This implies that decisions are made by endowing information with subjective value and integrating it with the value of extrinsic rewards, but the mechanism is unknown. Here, we show that human and monkey value judgements obey strikingly conserved computational principles during multi-attribute ...

具体做法为,等权配置四个因子smart beta组合,月度再平衡,如果某一个因子value spread跌破一倍标准差以下,则剔除该因子,剩余因子等权重配置,直到该因子回到一倍标准差以上。回测结果表明,择时能改善组合表现。 相比Research Affiliate,AQR的观点要保守得多,其主要观点如下[13]:...
「假设检验」,顾名思义,就是通过概率统计的知识来判断一个命题(如「A是一个合格的投手」,如「这枚硬币是均匀的」,如「\beta值大于0.75」)的真伪性。 这个命题便称作「虚拟假设,null hypothesis」,我们通常可以将该命题用数学语言表达出来,比如:「这枚硬币是均匀的」可以定义为「硬币出现正面的概率\theta为1/2...
如下图所示,记\alpha 为犯第一类错误「原假设为真、拒绝了原假设」的概率, \beta 为第二类错误「备择假设为真、接受了原假设」的概率,则: Power = 1 - \beta ,意为「原假设为假,也正好拒绝了原假设」的概率。 Power越大越好,但是理论上, β 越小, α 就越大,而我们要控制 α 。一般要求 Power>=...
