We show that a volatility-managed strategy using equity options provides higher alphas, increases Sharpe ratios, and generates significant utility gains for investors, exceeding those of the statistical volatility-managed counterparts. Return and volatility expectations embedded in options...

Metaverses have been evolving following the popularity of blockchain technology. They build their own cryptocurrencies for transactions inside their platforms. These new cryptocurrencies are, however, still highly speculative, volatile, and risky, motivating us to manage their risk. In this...

Information criteria (IC) are widely used tools for model selection in financial time series. In GARCH modelling of volatility, ICs can be used to select the correct number of lags and exogenous regressors when the relation between shocks and volatility is symmetric. When volatility is...

Despite the growing interest in realized stochastic volatility models, their estimation techniques, such as simulated maximum likelihood (SML), are computationally intensive. Based on the realized volatility equation, this study demonstrates that, in a finite sample, the quasi-maximum likelihood...
