Do We Need Intra-Daily Data to Forecast Daily Volatility? (version préliminaire)
Mercredi | 2012-05-16 B103 Denisa BANULESCU-RADU – Bertrand Candelon – Christophe HURLIN Considering mixed data sampling (MIDAS) regressions, we analyze the inuenceof the sampling frequency of intra-daily predictors on the accuracy of the volatility forecasts. We propose various in-sample and out-of-sample comparisons of daily,weekly and bi-weekly volatility forecasts issued from MIDAS regressions based on intra-daily regressors sampled at di erent frequencies. First, we show that increasing the frequency of the regressors improves the forecasting abilities of the MIDAS model. In […]
