Introduction: Poles do not save long-term in the context of future retirement. Higher benefits were to be provided by Open Pension Funds (OPF, Pol. otwarte fundusze emerytalne), thanks to investing in capital markets. However, the implemented reforms reduced the amount of funds transferred to them, and also made it possible to resign from saving them. In order to encourage Poles to save long-term, Employee Capital Plans (ECP, Pol. pracownicze plany kapitaowe) were introduced, to which auto-subscription will function for the first time in 2023.Objective: The main objective is to compare the investment effectiveness of OPF and ECP. The author also adopted an auxiliary objective i.e. recommendations for people considering joining the ECP.Materials and methods: The author used a critical analysis of the literature on the subject, quarterly continuous, compound rates of return, and the Sharpe ratio from 1 July 2020 to 31 December 2022, which were calculated for 10 OPF and 19 ECP, which allowed to avoid the survivorship bias in the analysis.Results: The effectiveness measures used do not allow for an unequivocal statement about which form of long-term saving gives higher results. The different structure of the portfolio in ECP than in OPF allows for greater risk diversification. This can be seen, for example, after the start of the war in Ukraine, when the results of OPF were worse than those generated by ECP, which is obliged to invest part of its funds in debt securities.
