Variance Decay

Variance decay is the tendency for an asset's price to decline over time as a direct result of volatility, often observed in leveraged tokens or volatility-linked derivatives. Because leveraged instruments reset daily, the volatility of the underlying asset causes the leveraged product to lose value even if the underlying price remains flat.

This is a form of mathematical erosion that disproportionately affects retail traders holding these assets long-term. In the context of crypto derivatives, understanding variance decay is vital for managing structured products and leveraged ETFs.

It serves as a hidden cost that can significantly undermine the profitability of a strategy. Traders must be aware of the reset mechanics inherent in these instruments.
