If the liquidation involves a loss for me - is there any form of guarantee or compensation (for example Investor Protection), alternative deductions in the declaration that can compensate all or part of a possible loss?

Investing in mutual funds always involves a risk. The value of your investment can go up and down depending on factors that affect the market including interest rates. Historical returns are not an indicator of future returns. Investors may lose part or all of the invested amount. For more information about risks, read more in the funds' fact sheets and general conditions.
