## Motivation

Do you wanna buy a share with  _high growth _**_or_**_ low valuation  _or  _high growth _**_and_**_ low valuation_?

## Description

Eventually, we desire to compound an investment portfolio based on two or more quantitative indicators. 

In this case, we can combine these indicators (or maybe their ranks) to create a new one and rank the best choices.

This combination can be linear (simple mean) or geometric (geo mean). 

When it's a linear, both indicators can result a higher value easier. But on gometic formula, both must have a high value to produce another high value.

## Formulas

Linear combination = (X + Y) * (1/2)

Geometric combination = (X + Y)^(1/2)
