Does anything beat 5-minute RV? A comparison of realized measures across multiple asset classes
能否超越五分钟已实现方差?跨资产类别的已实现测度比较
We study the accuracy of a variety of estimators of asset price variation constructed from high-frequency data (“realized measures”), and compare them with a simple “realized variance” (RV) estimator. In total, we consider over 400 different estimators, using 11 years of data on 31 different financial assets spanning five asset classes. When 5-minute RV is taken as the benchmark, we find little evidence that it is outperformed by any other measures. When using inference…
