This study proposes an extension of the realized stochastic volatility model by incorporating realized quarticityRQinto the volatility process. We employ an efficient Riemann Manifold Hamiltonian Monte Carlo method in a Markov Chain Monte Carlo algorithm to estimate parameters that could not be sampled directly. We investigate the empirical performance of the proposed model using data for six equity indices and 24 individual stocks listed on the Tokyo Stock Exchange. Parameter estimates and two Bayesian model selection criteria reveal evidence supportingRQ-based models that are driven by the maximum value ofRQdata. That model consistently outperforms benchmark realized stochastic volatility models in capturing spikes in volatility caused by largeRQvalues. Including such stylised facts as the asymmetric effect of returns-volatility and heavy tailed returns, our results reveal that the proposed models exhibit a weaker correlation between stock returns and volatility and heavier tails in equity returns.
