Subject and purpose of work: The work aimed at identifying and characterising the interdependence between Polish investors’ personal preferences in investing and their opinion about the effectiveness of investment strategies. It was examined how the adopted investment horizon, the level of risk aversion and the time spent daily on investing impact the interviewees’ experiences and opinions on the effectiveness of investment strategies. Materials and methods: As the survey method was employed, a questionnaire was sent to randomly selected Polish individual investors. The research material consisted of 652 questionnaire forms. Results: The study showed a relevant dependence between Polish investors’ personal preferences and their opinions on the effectiveness of the particular strategies. Conclusions: The interdependencies revealed in the study may be used by potential investors in the process of matching a strategy to individual needs so as to enhance the effectiveness of the choice. A higher awareness of the problem of matching an investment strategy to personal preferences will lead to improved effectiveness of capital allocation among Polish investors.
