How a bank Treasury would build your ETF portfolio

The portfolio is not the product. Confidence is.

DIY investors don’t lack access to ETFs — they lack the conviction to pick an allocation, implement it, and hold it through a crash. ETFWealthIQ publishes curated, backtested model portfolios on an open-source engine you can audit, so you can build an institutional-grade ETF portfolio in 60 minutes and hold it for decades.

Free · no credit card · 8 questions, no dollar amounts

Open source

The backtesting engine is MIT-licensed. Audit the math — no black box.

15–25 years

Backtested on actual historical ETF price data, not projections.

25+ years

Built by a systems engineer who ran risk machinery inside two bank Treasuries.

You chose DIY for a reason. The hard part isn’t access.

You opened the brokerage account. You funded it. You bought ETFs. The wall you actually hit is the one no free article solves: which allocation, in what proportions, why it holds in a downturn, and the conviction to not sell at the bottom.

The two usual answers both fail you. Pay 1–2% a year for what is, underneath, a model portfolio — or spend hundreds of hours parsing contradictory free content to build one yourself. ETFWealthIQ occupies the gap between them: organized clarity, backtested proof, and the behavioral scaffolding to hold the line.

The IQ Portfolio Blueprints

Four model portfolios. One for the investor you are.

Each Blueprint is a specific, backtested construction methodology — not a fixed-weight blog model. Numbers below are backtested on actual ETF data and are historical, not predictions.

Conservative Income

More than cash pays. Less than stocks can lose.

Built to earn meaningfully more than cash savings without putting your principal through stock-market-sized drops. For the investor who can’t stand to lose.

Backtested return
6.27%/yr
Worst drop
−12.2%

Steady Growth

Compound without the gut-punches.

Engineered for the smoothest path to long-term growth — it automatically dials down risk when markets get wild. For growing your money without the stress.

Backtested return
7.12%/yr
Worst drop
−17.0%

Balanced Growth

Real growth. Half the crashes.

Pursues long-term growth while absorbing major market crashes far better than a standard 60/40. For real growth without reliving 2008.

Backtested return
9.07%/yr
Worst drop
−24.7%
See the Blueprint →

Growth Maximizer

Stock-market growth. Softer landings.

Captures the long-run upside of owning stocks — built so crashes hurt less and you stay invested through them. For upside without the full panic.

Backtested return
10.49%/yr
Worst drop
−32.5%

Backtested returns from actual historical ETF data, computed by the open-source Boutquin.Trading engine (Conservative Income 15 yrs; the other three 25 yrs, as of 2026-04-19). Backtested performance is hypothetical and is not indicative of future results.

For retirees — the bucket allocator no competitor has

When your money has to cover both your withdrawals and your legacy.

Target-date funds answer one question: how should a saver glide toward a date? They can’t answer the retiree’s question — how much belongs in “safe” versus “growing” right now, when a single bad year during peak withdrawals can be catastrophic. The Decumulator combines all four Blueprints into a bucket-sized retirement portfolio, matched to a self-selected profile.

Why you can trust the numbers

Competitors describe their methodology. We publish the source code.

Every named mechanism — the Diversification Score, the Factor Fingerprint, the Stress Test, the Drawdown Catalogue — is a thin wrapper around an auditable algorithm in the MIT-licensed Boutquin.Trading engine. Anyone can read it, run it, or fork it. For an audience that inspects methodology before it trusts it, that’s the ultimate proof.

  • Backtested on actual ETF price data across multiple market regimes — not synthetic reconstructions.
  • Walk-forward validated out-of-sample, so Blueprints aren’t curve-fit to one history.
  • Every backtest paired with Monte Carlo uncertainty ranges — single paths can mislead.
  • The IQ Diversification Score separates a portfolio that looks diversified from one that is — one number that tells holdings which fall together apart from holdings that don’t.

Pierre Boutquin

Built by an engineer, not a marketer

The risk machinery banks use, rebuilt for you.

Pierre Boutquin spent 25+ years building the risk, rates, and pricing systems inside two bank Treasuries — modeling roughly $30B of hedged-book risk. The DIY investor has none of that machinery. So he rebuilt the institutional toolkit as an open-source engine, and the answers it produces as ETFWealthIQ.
