How often will I earn the returns with USD Cash Yield portfolio?

The underlying ETF is an accumulating share class. This means that the dividends received will be reinvested into the ETF instead of being paid out, increasing the value of your ETF.  Over time, you will compound your gains - thanks to the power of compounding interest. 

As always with StashAway, there are  no restrictions for withdrawals, so you can withdraw any amount from your portfolio, at any time.
