How is Save able to invest on my behalf?

When Save makes an investment in connection to your Market Savings program, Save is able to invest on your behalf with no extra cost to you.

For the Market Savings investments, we utilize the economic value of our customers' accounts, but not their accounts' principal itself. That economic value could be due to the interest that the customer forgoes. 

These external revenues to the customers' savings are used to finance the investment and ensure it doesn't lose value.
