  1. Note: The Value-at-Risk (VaR) estimates are expressed in percentage price changes. VaR estimates for the left tail in panel (a) are calculated from Eq. 24 using the general estimator of Fraga Alves et al. (2009) for \(\hat \gamma _{G}\). VaR estimates for the right tail in panel (b) are calculated from Eq. 23 using the Hill estimator. Estimates use k = 50 observations, or approximately 5.4% of the observations. The confidence intervals (conf. int.) at a 95% level in parentheses are based on a block bootstraps procedure
