| Tiivistelmä: | In this article the authors show, in the context of a volatility-timing trading strategy, that careful (optimal) separation of two volatility components (time-varying variance of the unobservable efficient returns, and the variance of the equally unobservable microstructure noise) of the observed stock returns yields substantial utility gains. |
