“…The period adopted for the research was characterized by an upward trend in the value of participation units. The reaction to the pandemic took place just before the pandemic period (Żebrowska-Suchodolska and Piekunko-Mantiuk, 2022). Therefore, this period was adopted to search for the variables determining fund selection.…”

From an investor's point of view, the appropriate selection of a fund is an important issue. When making such a choice, many elements should be considered. These include not only the fund's rate of return or its risk, but also the comparison of the fund's results with an appropriate benchmark. The aim of the research was to apply principal component analysis (PCA) to reduce the dimension of the indicators that help the investor in selecting a fund. The subject of the study was 15 equity funds that had been on the Polish market for many years. The research showed that it is possible to reduce the primary variables to two dimensions.

Research background Investment funds are an important part of the capital market. Household savings in this type of asset are increasing every year. From an investor’s point of view, the performance of funds is important. These, along with the risks, are what most often determine the choice of fund type and finally the specific fund. The performance of a fund is often determined by both the size of the fund and the application of the managers’ selectivity and market sense. Purpose The aim of this research is to investigate the impact of fund size on performance through the use of selectivity and market sense by managers. Dividing funds into size groups will allow the search for patterns in terms of managers’ use of market timing. Research methodology The research used a Treynor-Mazuy model as a market timing model and Ward’s method as the cluster analysis methods. The performance of the funds was determined using an investment performance indicator, i.e., Omega. Results The obtained results indicate that the funds are similar within the groups. However, there were differences in the results between the groups. During periods of high volatility, it is recommended to invest in units of funds with an average size below the median. Novelty The added value is the study of market timing in groups of funds similar in size. In each group, the results of the Treynor-Mazuy model estimation, and the Omega investment efficiency index were determined, and the differences in the obtained results between the groups were examined. Finally, all funds were clustered using the Ward method.
