Portfolio Lab
7.4 years of out-of-sample evidence

Three portfolios. Built to beat the index on risk-adjusted return.

Each portfolio holds a small set of carefully chosen, diversified investments — all tradable in your Hargreaves Lansdown ISA. We compare every portfolio against its natural benchmark so you can see exactly what you're getting versus a passive index fund.

How to think about it

£20,000 starting amount

The full annual S&S ISA allowance. We show how each portfolio would have performed if you'd invested this amount at the start of the live track-record period.

Weekly rebalancing

Portfolios are reviewed every Monday and adjusted to keep diversification on track. All trading costs (dealing fees, stamp duty, FX, spread) are deducted from the curve.

7.4 years of evidence

The track record runs from January 2019 to May 2026. Every data point was produced with no foreknowledge — the portfolio at any given week only used information available at that time.
