Seminar abstract

Under a high-frequency and high-dimensional setup, the researchers establish a framework to estimate the factor structure in stock volatility.

They show the consistency of conducting principal component analysis on realized volatilities in identifying the factor structure in stock and idiosyncratic volatilities.

Empirically, with strong empirical evidence, it is proposed a single factor model for stock volatility, where volatility is represented by a common volatility factor and a multiplicative lognormal idiosyncratic component.

Further utilising the proposed factor model for volatility forecasting and show that our proposed approach outperforms various benchmark methods.
