I had a lot of fun learning new ways to do things we struggle with normally. Although numbers such as 0.10, 0.05 and 0.01 are values commonly used for alpha, there is no overriding mathematical theorem that says these are the only levels of significance that we can use.

From the perspective of a portfolio analyst, the concept of alpha is very important as it is used to assess the ability of a portfolio manager to generate a risk-adjusted return.

By Madhuri Thakur | Reviewed By Dheeraj Vaidya, CFA, FRM. Thus the sum of the roots is (α + β)2 − 2αβ αβ. Angular acceleration is the time rate of change in the angular velocity. In other words, alpha is the assessment tool to gauge the ability of a portfolio manager to generate a higher return on a risk-adjusted basis. Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. The Feynman-alpha formula can now be written in the form (9.115) Y ( t ) = μ Z Z ( t ) Z ( t ) = ∑ i = 0 6 Y i ( 1 − 1 − e − α i t α i t ) , where α i = − s i , i = 0, 1, …, 6, and as in the previous section, the variable t now stands for the measurement time length.
