Alpha and beta are fundamental concepts in finance that help investors measure and understand the performance and risk of investments relative to the broader market. Beta, often considered first, quantifies an asset's volatility or systematic risk compared to the market as a whole. A beta of on...
Calculation Method:It goes without saying that each has a different way of being calculated. Alpha is formulated using thecapital asset pricing model (CAPM)formula which considers an investment's actual return, risk-free rate, and beta. Beta, on the other hand, is calculated through regression ...
Alpha测试主要看有没有功能缺失或系统错误,Alpha测试完后一般不会有大问题了,然后把软件拿给用户测试,称为:beta测试,主要是看用户对软件外观,使用方便等的反映。 如果beta1版用户反映有问题,拿到公司修改,改完后发布beta2版,还有不满意的地方,再改,再发布beta3版,直到用户满意,或正式版发布为止。 软件版本里的Fi...

1)有正的阿尔法,即投资标的回报高于市场回报。这一条似乎不用太多解释。 2)有低的贝塔,即该投资标的回报的波动性和市场几乎不相关。这是什么原因呢?主要有两点。首先大部分人在进行投资的时候,会首先购买市场(比如购买上证180指数基金),所以在大部分人的投资组合之中,他不缺贝塔(还记得么,市场的贝塔为1)。其次...

Alpha TC1 (αTC1) and Beta-TC-6 (βTC6) mouse islet cell lines are cellular models of islet (dys)function and type 2 diabetes (T2D). However, genomic characteristics of these cells, and their similarities to primary islet alpha and beta cells, are undefined. Here, we report the epigeno...
