## Variance Drain

Variance drain is a synonym for volatility drag, describing how the dispersion of returns negatively impacts the final compounded value of an investment. It quantifies the gap between the arithmetic average return and the actual realized growth of a portfolio.

High variance in price movement directly leads to a larger drain on capital over time. In quantitative finance, this is modeled by subtracting the variance divided by two from the expected return of an asset.

This drain explains why assets with high volatility must demonstrate superior fundamental performance just to achieve the same net growth as a stable asset. For crypto-assets, which exhibit high variance, the drain is a significant barrier to long-term wealth preservation.

It forces investors to consider risk-adjusted metrics rather than raw price percentage gains. Managing variance drain involves strategies that reduce exposure to extreme, non-directional price swings.
