Abstract
Under a simple setup we investigate the impact of parameter uncertainty on risk-adjusted returns that correspond to expected exponential utilities. In particular, we present rules-of- thumb for the impact of parameter uncertainty on the risk-adjusted returns of non-learning and learning investment strategies. These enable investors to easily approximate how much additional wealth they would need now to compensate for parameter uncertainty
