Question

what is alpha beta in math language​

Answer 1

Answer:

Alpha is the excess return on an investment relative to the return on a benchmark index. Beta is the measure of relative volatility. Alpha and beta are both risk ratios that calculate, compare, and predict returns.

Answer 2

Alpha and beta are just no different to m, n, x, y or anything else you want to call any unknown or variable. ... If alpha and beta are roots of the quadratic equation ax²+bx+c=0 then form an equation whose roots are alpha+1/beta, beta+1/alpha?
