Volatility Surface

A volatility surface is a graphical representation of implied volatilities for options across different strike prices and maturities, providing insights into market expectations of future price fluctuations. Current research focuses on improving the accuracy of volatility surface predictions using advanced techniques like deep learning, including reinforcement learning and variational autoencoders, often incorporating sentiment analysis or addressing data sparsity through imputation methods. These advancements aim to enhance the precision of option pricing, hedging strategies, and risk management, with applications ranging from portfolio optimization to the detection of model tampering. The improved understanding and modeling of volatility surfaces have significant implications for both theoretical finance and practical trading applications.
