Other investigations have refined the differences between arithmetic and geometric means, thereby enhancing our understanding of the interplay between these fundamental operations, and offering ...

Arithmetic returns, also known as simple returns, are calculated by taking the difference between the ending value and the beginning value of an investment and dividing it by the beginning value.

The goal of this short note is the presentation of an elementary proof of the wellknown inequality between the arithmetic and geometric means. Our approach shows that the proof reduces to simple ...
