It is commonly used in various fields, including science and mathematics, to denote the beginning or primary position in a sequence. In finance, the term "alpha" refers to the excess return on an investment compared to a benchmark index, indicating the performance of a portfolio manager. In the context of social dynamics, "alpha" is used to describe individuals who exhibit leadership qualities or dominant behavior within a group.
