Model Risk Parameters
Model Risk Parameters are the specific inputs and assumptions within a quantitative formula that determine its output and accuracy. In the context of options trading, these might include volatility estimates, interest rate assumptions, or time-to-expiry calculations.
If these parameters are set incorrectly or based on outdated data, the resulting option price will be misaligned with the actual market value. These parameters must be calibrated regularly to reflect the current market regime.
In crypto, volatility parameters are notoriously difficult to fix because of the asset class's inherent instability. Traders use these parameters to determine the Greeks, such as Delta and Gamma, which dictate hedging requirements.
Misestimating these values can lead to an unhedged exposure that leaves the trader vulnerable to sudden price swings. Constant adjustment and sensitivity testing of these parameters are essential for risk mitigation.
