Understanding Harmonic Mean in Financial Analysis
A comprehensive guide to using harmonic mean for financial calculations, portfolio analysis, and investment decisions.
What is Harmonic Mean in Finance?
The harmonic mean is particularly valuable in financial calculations where rates, ratios, or speeds are involved. It provides a more accurate average when dealing with rates of return, price-to-earnings ratios, and other financial metrics.
The harmonic mean is calculated as:
H = n / (1/x₁ + 1/x₂ + ... + 1/xₙ)
where n is the number of values, and x₁, x₂, etc. are the individual values.
Applications in Finance
