Diversification

Category: Investing

Definition

In finance, diversification is a risk management strategy of combining a variety of investments within a portfolio. A diversified portfolio contains a mix of distinct asset types and investment vehicles in an attempt to limit exposure to any single asset or risk.

Example

Instead of investing all your money in a single tech stock, you diversify by investing in a mix of stocks from different industries (tech, healthcare, consumer goods), bonds, and real estate. If the tech sector performs poorly, your losses are cushioned by potential gains in other sectors.

Calculation / Formula

There is no single formula for diversification itself, but it is a core principle in Modern Portfolio Theory, which uses statistical concepts like variance and correlation to build an optimal portfolio.
