Why InvestLab

Anyone can build a good-looking backtest. Knowing what deserves your trust is harder.

AI can generate strategies, optimise rules and make almost anything look convincing in hindsight. InvestLab adds what's harder to automate: professional judgment, real-world implementation experience, and complete transparency about the trade-offs.

01PROFESSIONAL JUDGMENT

Experience to separate robust ideas from attractive backtests.

15 years across multi-asset, risk parity, alternative risk premia and global macro — applied to deciding what is worth using, what isn't, and why.

02RADICAL TRANSPARENCY

See exactly what you're buying into — including the weaknesses.

Every rule and live allocation is visible, along with where a strategy struggles, what can break it, and what needs adapting for an individual investor. No sponsored products. No black boxes.

03THE FULL INVESTMENT PROCESS

From understanding a strategy to fitting it into your portfolio.

Research it, test it, adapt it, combine it with what you already own, and implement it — all in one platform.

Questions

Before you ask

Is InvestLab for me if I already have a portfolio?

Yes. You can keep your existing ETFs, funds and high-conviction positions, then use InvestLab strategies and portfolio tools to see what complements them, what may be missing, and how much of each belongs in the mix.

Do I need to replace my current investments?

No. InvestLab is designed to help you build around what you already own, not force you into a model portfolio.

Are these just good-looking backtests?

No strategy is judged on historical returns alone. The research focuses on the economic rationale, robustness, failure modes, costs and implementation — and the strategies then run live, in the open.

Why not just buy a global index fund?

That can be a perfectly reasonable approach. InvestLab is for investors who want to go further — diversify across different return drivers, reduce reliance on a single market outcome, and build a more deliberate portfolio process.

How much time does this actually take?

As little as 15–30 minutes a month to follow a live strategy. You can build or restructure a portfolio in an afternoon, then go deeper into the research and tools only when you want more conviction.

What if I don't know which strategy to use?

Each strategy explains what role it is designed to play, when it tends to work, where it can struggle, and how it might fit alongside the rest of a portfolio. Pro members can also work through these decisions in the weekly sessions.

What's included free?

Two live strategies — Balanced Core and Dual Momentum Pivot5 — plus restricted backtesting and the core research. No card required. If the free plan alone makes you a better investor, that's a win for both of us.

Do I need a specific broker?

No. Strategies are built from liquid ETFs and show exact target weights and rebalance instructions. You execute at whichever broker you already use — InvestLab never touches your money.

Is this financial advice?

No. InvestLab is an educational and analytical platform: it shows you strategies, evidence, and tools, and explains the trade-offs. What you invest in remains your decision — and past performance never guarantees future results.

The cost of a weak portfolio rarely shows up when markets are easy.

It shows up when diversification fails, losses become uncomfortable, and you start changing the plan at the worst possible time.

Build the process before you need it — then decide how far you want to take it. Follow strategies in as little as 15 minutes a month, or use the research, tools and support to become a more capable, independent investor.
