Return Dispersion
Return dispersion measures the spread or variability of returns across different assets or time periods within a portfolio. High dispersion indicates that the assets in the portfolio are moving in different directions or with significantly different magnitudes, which can either increase or decrease overall risk.
In the context of volatility drag, understanding return dispersion is crucial because it helps identify which components of a portfolio are contributing most to the variance drain. For crypto investors, managing dispersion is a key part of diversification strategy.
It is not enough to simply hold many assets; one must understand how their individual variances interact to affect the total portfolio growth. High dispersion can lead to unpredictable outcomes, making it harder to forecast future returns.
It is a core concept in portfolio theory and risk assessment.
