Within the context of volatility timing and portfolio selection this paper considers how best to estimate a volatility … model. Two issues are dealt with, namely the frequency of data used to construct volatility estimates, and the loss function … used to estimate the parameters of a volatility model. We find support for the use of intraday data for estimating …
