When you make a cash-in through Versa Cash, Versa purchases units from Affin Hwang's Enhanced Deposit Fund (AHAM EDF) on your behalf.
Once your cash-in is reflected in your Versa Cash balance, you will start earning interest which is then compounded. The accumulated interest reflects in your Versa Cash balance whenever the unit price of the fund increases.
So, if you consistently make cash in through Versa over the long term, your money will constantly be reinvested to generate more returns.
