Purpose The purpose of our study was to investigate the changing nature of volatility during the last 80 years. Like in an American study, we tried to find some trends in the risk of stocks and bonds that would have an impact on the balance of a portfolio of stocks and bonds. At the same time we investigated the influence of inflation on the choice of portfolio. Methods We have used standard statistic tools and formulas to obtain our results. In most cases it was a matter of calculating average and standard deviation. We have also put together some portfolios, both trivial and in some sense optimal. Result We found that it is hard to see any trend in volatility. On the Swedish market the volatility is too random. But it is obvious that stocks should be a part of our portfolio. It also shows that inflation has a significant impact on the allocation of our assets whitin the portfolio.
