Pricing Kernel (Non) Monotonicity and conditional information
Compares CDI and classical pricing kernel estimation methods under volatility jumps, analyzing empirical and simulated S&P500 and Bitcoin option data.
What it examines
This study examines the pricing kernel puzzle by investigating if the Conditional Density Integration (CDI) method, which aligns risk-neutral and physical density estimates, remains reliable when volatility jumps occur. Using S&P 500 and Bitcoin options data, the paper tests whether volatility shifts distort kernel trends and affect model consistency.
What it concludes
The study shows that CDI and classical methods produce inconsistent pricing kernel estimates, especially during volatility shifts. This research highlights the need for robust option pricing models and can be applied to improve risk management and trading strategies in traditional and cryptocurrency markets.
Evidence objects
Investigators reveal the CDI methods performance depends on parameter choices such as the number of moments and knots, challenging previous claims regarding its reliability in capturing investor risk preferences effectively.
