This study examines latent shifts in the conditional volatility and correlation for the U.S. stock and T-bond data … using the two-state Markov-switching range-based volatility and correlation models. This paper comes up with clear evidence … of volatility regime-switching in stock indices and T-bond over the crisis period. As regards the process of correlation …

volatility. However, this predictive power of the LOB declines during extreme market-wide movements. We also find that buy orders … are more informative for future price volatility than sell orders, but sell (buy) orders become more informative during …

Risk diversification is the basis of insurance and investment. It is thus crucial to study the effects that could limit it. One of them is the existence of systemic risk that affects all the policies at the same time. We introduce here a probabilistic approach to examine the consequences of its...

Expected Shortfall (ES) has been widely accepted as a risk measure that is conceptually superior to Value-at-Risk (VaR). At the same time, however, it has been criticized for issues relating to backtesting. In particular, ES has been found not to be elicitable which means that backtesting for ES...

Necessary and sufficient conditions for the subadditivity of Value-at-Risk (V aRα) for portfolios of bonds are presented under various dependence assumptions. For sufficiently large α, V aRα is subadditive. However, for any α one can construct portfolios for which V aRα is superadditive.
