GEM Philosophy

Global Equity Momentum is built on the premise that markets exhibit strong, persistent trends. Rather than holding a static mix of stocks and bonds, it invests 100% of its capital in the equity index with the strongest relative momentum (S&P 500 or MSCI ACWI ex-US). When both indexes trend downward and fail to outperform risk-free cash, absolute momentum triggers a circuit-breaker, shifting 100% to Aggregate Bonds to hedge against severe market downturns.

All Weather Philosophy

Ray Dalio's All Weather Portfolio is structured around risk-parity. It splits capital into assets that perform well in different economic scenarios: inflation (gold, commodities), deflation (long-term treasury bonds), economic growth (stocks), and recessions (intermediate treasury bonds). By weighting the portfolio to balance the volatility contributions of each asset, it delivers steady growth with low historical drawdowns.

Side-by-Side Pros and Cons

GEM Strengths & Limits

  • Higher returns (12.3% CAGR vs 7.2%) over 10-year test cycle.
  • Active downside protection via absolute trend-following.
  • Allocates to international stocks only when they outperform US.
  • Subject to "whipsaw" losses in sideways, non-trending markets.
  • Tax-inefficient in taxable accounts due to monthly asset rotation.

All Weather Strengths & Limits

  • Extreme simplicity — buy and hold once a year rebalance.
  • Very low transaction costs and minimal maintenance.
  • Protects against inflation through gold and commodities.
  • Lower nominal returns due to high allocation in fixed income (55%).
  • Vulnerable to sustained periods of high interest rates crashing both stocks and long bonds.

Which Strategy is Right For You?

Choose GEM if: You are comfortable with monthly monitoring, invest via tax-advantaged accounts, and want to maximize long-term growth while protecting capital from major bear markets.

Choose All Weather if: You prefer a hands-off, "set and forget" approach, have a taxable investment account where frequent turnover triggers capital gains tax, and want a very smooth equity curve with minimized drawdowns.
