A new research paper explores the challenge of accurately recovering latent risk-neutral densities from option pricing data, even when option prices themselves are accurate. The study utilizes two benchmarks: a controlled synthetic dataset and a chronological NIFTY market dataset. Findings indicate that while a two-component lognormal mixture model performs well overall, specialized neural network models like DeepONet and quote transformers show strengths in specific error metrics, suggesting that the optimal approach is dependent on the target application.
