Walk-Forward Portfolios, Explained: Why Chasing Winning Strategies Fails and What Works Instead
Rotating into whatever strategy performed best recently is the most requested feature in tactical investing, and the most dangerous one. A deep dive into walk-forward optimization: the rolling out-of-sample engine, the 8 ranking criteria, the max-weight cap, and a real portfolio that runs on it.

We Extended Our Backtest to 1974. Here Is the 4% Rule Through the 1970s Stagflation.
A few weeks ago we measured safe withdrawal rates across 50+ tactical strategies, and the fairest critique was that our data started in 1990. So we extended HAA's backtest to 1974, through the stagflation that nearly broke the 4% rule. The safe rate came down, and that makes it more believable.

Seven Leveraged Tactical Strategies: How They Work, What Breaks Them
Seven new strategies in the catalog today, six of them leveraged. They span the named names in the r/LETFs community (RNAProf, u/Wongkok, u/Low-Initiative-1327), a published author (David Alan Carter), and two r/LETFs-classic ideas (200d-SMA TQQQ trend and RSI/SMA dip-buying) that BestFolio has stabilized into shipping form. The point of this writeup is not a sales pitch. It is the rule set, what each one does well, and what breaks it. Kelly 3sig/6sig/9sig deliberately held back: the 9sig 99.73% dot-com drawdown makes that family unsuitable for a wider release.

Which TAA Strategies Actually Work in Europe: A UCITS Substitution Guide
European investors hit a wall the moment they try to run a US TAA strategy through IBKR: PRIIPs blocks AVUV, DBC, and most US-domiciled ETFs from retail purchase. The substitutes exist on XETRA and LSE, but they're not all equal. Some strategies translate cleanly (HAA, GEM, Permanent Portfolio). Others lose 50 to 100bps of CAGR per year through methodology drift on the small-cap-value sleeve. A few don't really translate at all. Here's the working playbook, split into three tiers.

Why 50+ TAA Strategies All Beat the 4% Rule (And Where Bengen Still Wins)
We computed Bengen-style rolling 30-year safe withdrawal rates for 80 variants across 51 published TAA strategies. Every single one clears 4%. The best unleveraged TAA strategies (VAA-G4 SmartStack 15.3%, HAA SmartStack 14.2%) sustain real withdrawal rates 3-4x higher than Classic 60/40. Why TAA defeats sequence-of-returns risk, and four honest reasons you should still anchor your retirement plan closer to 4% than 15%.

Kelly 9Sig Revisited: What We Got Wrong, What the Faithful Rules Actually Show
Our April 11 piece arguing 9Sig would ruin you used a flawed engine. We rebuilt it with the full Kelly rulebook: 10% bond floor, 90% buying-power throttle, 8-quarter 30-Down lookback, skip-2-sell-signals, base reset, spike reset. The corrected 9Sig drew down 99.7% through the dot-com crash, worse than the 99.3% we originally reported. The closed-system thesis survives. Here are the receipts.

Dual Momentum's 2022 Problem: Why Canary Models Worked When GEM Didn't
2022 was the cleanest A/B test the tactical asset allocation community is ever going to get. Classic dual momentum strategies (GEM, ADM, CDM) lost between 10 and 24 percent. Three Keller canary-family strategies (BAA-G4, BAA-G12, HAA) closed the year with positive returns. Same tactical framework, completely different design choices, and a lesson about which defensive asset actually defends when the "safe haven" bond is the thing falling.

Why Jason Kelly's 9Sig Will Ruin You: A 99% Drawdown Hidden in Plain Sight
Kelly's 3Sig, 6Sig, and 9Sig systems are marketed as mechanical rebalancing genius.

How to Add Gold and Managed Futures Without Giving Up Your Equity Upside
Classic diversification has felt like a tax for a decade — because funding it by selling equities in a bull run is the wrong question. A new Quantica Capital paper (March 2026) reframes it as a stacking problem, and spells out exactly why we built SmartStack™: layer gold and managed futures on top of any TAA strategy without selling what is working, using leveraged ETFs at fractional weight. No margin, no futures account.
