Here are the Index annual price returns in Icelandic kronas. In 26 years out of 36, the Index generated positive price returns in US dollars. If we convert the Index and express it in Icelandic kronas (ISK), then we get 26 positive and ten negative return years. Last year, the return of the Index in USD was 21.8%. However, over the same period the USD decreased 4.1% in value versus the ISK – resulting in a 16.8% positive return for the Index in ISK. 

The third chart shows the annual price returns in the context of the mean and the standard deviations. We have 19 years with above-average (blue line) returns, five years where the returns are more than one standard deviation above the mean and four years where the returns are more than one standard deviation below the mean. However, we have only two years (1988 and 1989) where the positive return is above two standard deviations and one year (2002) where the negative return is below two standard deviations.
