Launched Apr 18, 2016About this Strategy
The Golden Butterfly portfolio was created by Tyler at Portfolio Charts as an evolution of Harry Browne's Permanent Portfolio. It keeps the four pillars but replaces 20% of the broad stock allocation with small-cap value, adding a factor premium backed by the Fama-French size and value research. Five equal 20% slices: SPY, IWN (small-cap value), TLT, SHY, and GLD.

- Dual Momentum's 2022 Problem: Why Canary Models Worked When GEM Didn't2022 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.
- Strategy Spotlight: Golden Butterfly — A Smarter Permanent Portfolio With a Small Cap Value TwistThe Golden Butterfly enhances Harry Browne's Permanent Portfolio by replacing the cash allocation with small cap value stocks — historically the highest-returning equity factor. With a 7.9% CAGR and just -19.9% max drawdown over 25 years, the Golden Butterfly offers a compelling middle ground between safety-first fixed allocations and aggressive growth strategies.
