GEM Philosophy
Gary Antonacci's GEM uses a two-step momentum filter. First, relative momentum compares US equities against international equities, selecting the leader. Then, absolute momentum checks whether the winner beats T-Bills — if not, the portfolio rotates to bonds. This dual filter captures global equity upside while protecting against prolonged bear markets.
Permanent Portfolio Philosophy
Harry Browne's Permanent Portfolio splits capital equally (25% each) among stocks, long-term government bonds, gold, and cash (T-Bills). Each asset class is designed to thrive in one of four economic states: prosperity, deflation, inflation, and recession. The quarterly rebalancing to equal weights captures mean-reversion gains across these structural allocations.
Key Differences Explained
This comparison represents the extremes of the risk spectrum. GEM aggressively rotates 100% of capital pursuing maximum momentum returns, while the Permanent Portfolio defensively splits capital into four equal parts. GEM's 12.3% CAGR nearly doubles the Permanent Portfolio's 6.8%, but the PP's maximum drawdown of -10.5% is far gentler than GEM's -17.8%.
- Strategy Type: GEM is a tactical, actively-managed approach. Permanent Portfolio is a passive, buy-and-hold approach.
- Return vs Risk: GEM delivered 12.3% CAGR with -17.8% max drawdown (Sharpe: 0.72). Permanent Portfolio delivered 6.8% CAGR with -10.5% max drawdown (Sharpe: 0.58).
