Thesaurization means that income—such as interest, dividends, or trading profits—is not distributed to investors but automatically reinvested into the investment. As a result, invested capital grows continuously, allowing the compound interest effect to have a significant long-term impact on overall returns. In accumulating funds or investment models, generated income is immediately reinvested, increasing the value of the investment units. In many jurisdictions, reinvested earnings are still subject to taxation, even if they are not paid out. Within DEECKE Financial Solutions, the StabilityFrame model allows investors to choose between reinvestment (thesaurization) and quarterly distributions. Thesaurization is particularly suitable for long-term investors aiming to maximize wealth accumulation.
