## Portfolio Variance

Portfolio variance is a statistical measure of the dispersion of returns for a portfolio of assets, indicating the overall risk level. It is calculated based on the individual variances of the assets and the correlations between them.

By combining assets that are not perfectly correlated, investors can reduce the total portfolio variance, a process known as diversification. In the context of crypto, where assets often show high correlation during market stress, achieving true diversification can be difficult.

Analysts use portfolio variance to optimize asset allocation, aiming to achieve the highest expected return for a given level of risk. It is a cornerstone of modern portfolio theory and a standard tool for institutional investors managing digital asset portfolios.

Understanding how to minimize variance is key to building resilient long-term investment strategies.
