EconPapers: Measuring downside risk — realised semivariance
WebBy regressing various realized volatility measures (with/without jumps) on trading volume and trading frequency, our results feature a contemporaneous and largely positive relationship. Furthermore, we test whether the volatility-volume relationship is symmetric for energy futures by considering positive and negative realized semivariance. WebJun 1, 2024 · Barndorff-Nielsen et al. (2008) developed downside realized semivariance (DRV) and upside realized semivariance (URV) to measure variation of prices. It is found that the DRV yields better volatility and returns predictions than the RV (Patton and Sheppard, 2015; Bollerslev et al.,2024). godly color mm2
