Modelling and forecasting stock and stock market volatility. / Craig Paul Gower

Swansea University Author: Craig Paul Gower

Abstract

The examination of stock price volatility has come under increased scrutiny due to the large swings in stock price movements that have occurred with greater frequency than the historical average. Additionally, the substantial increases in the volume of options trading has increased the importance of...
