Convexity Exposure
Convexity exposure, often represented by the Greek letter gamma, measures the rate of change of an option's delta with respect to the underlying asset's price. A portfolio with positive convexity benefits from larger price moves, as the delta increases in a favorable direction.
Conversely, negative convexity can lead to accelerating losses if the underlying price moves against the position. Traders actively manage this exposure to ensure their portfolios do not become dangerously sensitive to market swings.
In the context of options trading, convexity is what makes hedging non-linear and complex. It is a critical risk factor for any strategy involving significant option holdings, especially in high-volatility environments like digital assets.
Managing this exposure involves balancing gamma across different strikes and expirations to ensure the portfolio's risk profile remains manageable. It is the primary driver of delta drift and a key focus for professional traders.
