costing you.
Arken analyses your whole portfolio and finds the overlapping funds, fee drag and concentration you can't see on your broker's dashboard.
Your whole portfolio, scored 0–100 in minutes.
One health score across the four things that actually move your returns.
- Fees, diversification, concentration risk, and allocation alignment — each scored, so you see exactly what's working and what's holding you back.
- No guesswork, no spreadsheets. Just a clear number and what to do about it.
