ISA Lens

ISA diversification

Portfolio diversification calculator

A portfolio can look diversified because it has several ETFs, while still leaning heavily into the same US technology companies. ISA Lens scores diversification from look-through concentration, ETF duplication, sector mix, geography, and AI theme exposure.

Built for UK investors

The workflow assumes GBP values, Stocks & Shares ISA habits, and common UK-listed UCITS ETFs rather than a US-only ticker universe.
