Overfitting: what it is, why it kills tactical strategies, and why ours survived

A reader called our flagship an overfitting masterpiece. So we ran the tests that could convict it: 700 parameter configurations, a deliberate cherry-pick, 60 random universes, and a post-publication study of 63 strategies. Our published settings ranked 2nd of 700, the pre-2019 ranking predicted nothing about what followed, and the decay evidence leans one way without proving it.

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.

PRIIPs blocks EU retail from AVUV, DBC and most US-domiciled ETFs, so running a US TAA strategy in Europe means substituting UCITS funds.

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.

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.
