摘要

Forecasting stock volatility is crucial to many fundamental problems of financial field, such as risk management, asset pricing and asset allocation etc. This paper proposes a new Adaptive Network-Based Fuzzy Inference System (ANFIS) which adaptively adjusts fuzzy inference rules by using Fruit Fly Optimization Algorithm (FOA). Empirical analysis is made on the Shanghai A-share sample stocks. Compared with ANFIS, the experimental results reveal that this new model can accurately and successfully forecast the sample stocks' volatility.
