First, ask yourself for what purposes you need the money and in how much time.
Also clarify how much risk you allow, namely the return is a reward for the risk taken! If you do not want to take risks, leave money in a safe portfolio (deposit and savings account), regardless of profitability. Once you have decided, you can choose the appropriate funds based on this. Ensure an appropriate diversification of your investments (worldwide, all industries) and adjust their composition to the period of savings.
The golden rule: the longer the savings period, the more equity investment can be in the portfolio; the shorter the period, the more bond or even cash investments must be in the portfolio.
