We quantify the effects on contingent claim valuation of using an estimator for the volatility of a geometric Brownian … motion (GBM) process. That is, we show what difficulties can arise when failing to account for estimation risk. Our working … problem uses a direct estimator of volatility based on the sample standard deviation of increments from the underlying …

We find that inspection of the recursive eigenvalues is not useful to detect a break in the … adjustment coefficients, whilst recursive estimation of the coefficients can only indicate non-constancy, but not the exact … breakpoint. Rolling estimation is found to perform better in detecting non-constancy in the parameters and their true value after …
