Volatility Drag
Volatility drag is the mathematical reduction in the compound annual growth rate of an investment caused by price volatility. Even if an asset's average return is positive, frequent and large price fluctuations can lead to a lower realized return over time compared to a less volatile asset with the same average return.
This occurs because large percentage losses are harder to recover from than smaller ones, creating a negative compounding effect. For traders and investors, understanding volatility drag is crucial for evaluating the true performance of their portfolios and selecting appropriate assets.
It highlights the importance of risk-adjusted returns and the potential benefits of diversification. Minimizing this drag is a key goal for long-term wealth preservation.
