It is only useful to me to have my portfolio linked to 22 seven if I can see:
1. The total annualized return on my investment (calculated using contribution values - from transaction history - and current value).
2. The monthly return - for kicks.
3. Investment advisor showing how a change in contribution (maybe a slider) to my portfolio will change the value of the portfolio at specific end date (e.g. retirement) based on historical return on the same portfolio.
4. A total fee calculator to show how the investment product is eating into returns.
5. A JSE market benchmark.
Right now all you're telling me extra, for volunteering pretty sensitive data to you, is my total net worth. Fair trade? I think not.
