Outline of Final Research Achievements

This project aimed to derive an expression of the mean-variance hedging for the Barndorff-Nielsen and Shephard(BNS) model and develop its numerical scheme. The results obtained are (1) derivation of local risk-minimizing for digital options, (2) derivation of decomposition and approximation formulas for option prices for the BNS model, and (3) computation of option prices for the BNS model using unsupervised deep learning.

Academic Significance and Societal Importance of the Research Achievements

ジャンプ型モデルに対するmean-variance hedgingの導出は難しく、本研究ではその準備段階しかできなかった。しかし、伊藤解析を用いた分解公式の研究や深層学習を用いたアプローチなど新たな試みに挑戦したことで、研究手法の幅を拡げることに成功した。様々な手法を組み合わせることにより、ファイナンスにおける数学的知見を金融実務へ還元する礎を築けたものと確信している。
