Convexity Risk
Convexity risk refers to the potential for losses arising from the non-linear relationship between an option's price and the underlying asset's price. This non-linearity is defined by gamma, which measures the acceleration of the option's price change relative to the underlying.
A portfolio with high positive convexity benefits from large price moves, while negative convexity can lead to compounding losses as the hedge becomes increasingly inadequate. In financial derivatives, convexity risk is a primary concern for market makers who sell options and must manage the resulting negative gamma.
If the market moves sharply against their position, the cost of re-hedging increases exponentially. This risk is amplified in cryptocurrency markets due to high leverage and the potential for rapid liquidations.
Managing convexity risk involves balancing the portfolio's exposure to ensure that the cost of hedging does not exceed the potential profits from the option premium.
