If a WiseAlpha investor sells their Fractional Bonds on our secondary market (further described here), WiseAlpha charges them a 0.25% Sale Fee based on the principal amount of the Fractional Bonds sold.
For accounts that use Robowise the Sale Fee is taken only when the investor wants to liquidate all or part of their portfolio. Transactions (buying and selling) employed by Robowise in order to diversify and maintain the portfolio do not incur Sales Fees.
