Snapshots of Contract-Level Binary Prediction of Implied Volatility Surfaces Using Transformers

Key Points

This research aims to develop a model for predicting implied volatility movement for S&P 500 options using transformer architecture.
Developed a temporal and cross-sectional transformer architecture (TCTA) for prediction.
Tested the performance of TCTA against comparison models.
Focused on next-day implied volatility movement predictions.
TCTA outperformed comparison models in forecasting implied volatility change.
Demonstrated accurate predictions of next-day movements for individual S&P 500 option contracts.

Abstract

Quickly apply original, key PMR-published papers with Snapshots—a short article companion that distills PMR research into compressed, digestible takeaways, so you can put the paper’s core ideas to work in your investment process—fast. This Snapshot article is based on research proposing a temporal and cross-sectional transformer architecture (TCTA) that predicts next-day implied volatility movement for individual S&P 500 option contracts and outperforms comparison models in forecasting the magnitude of implied volatility change.
