In conjunction with last year's major elections and polls, several economic analysts published forecasts of economic cave-ins, falling stock markets and long time for economic recovery. What can be found afterwards is that these analyzes were not always correct. Certainly, the stock market often reacted negatively initially, but it recovered rapidly. How come these analysts predicted wrongly? Were the analysts, market actors or the market in their own right wrong? The purpose of the study is to investigate whether the answers to these questions lies in the behavior of different investor categories in the stock market. An unusually volatile stock market was in place during the periods surrounding these polls and large movements have been observed several times in the past, not least during the major crises that the stock market has suffered over the past 20 years. Therefore, the study focuses on these crises. Through quantitative observations at aggregated level, movements in shareholdings between the players were studied. Which showed a distinctly negative link between sophisticated and less sophisticated groups of players in the stock market. These observations were then combined with an individual-oriented perspective in the form of semi-structured interviews. In these interviews, deviations were sought in the return requirements between the groups, as well as possible reasons for these deviations. It was established that the less sophisticated group generally had a lower rate of return than the sophisticated group, which was interpreted as an effect of the difference in experience and knowledge between groups, however, no signs of irrational strategies in the stock market could be observed.
