GEM Strategy 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.

Classic 60/40 Philosophy

The 60/40 portfolio is based on Modern Portfolio Theory (MPT), assuming that stocks and bonds are uncorrelated assets. It allocates a fixed 60% to stocks for growth and 40% to bonds for income and stabilization. Rather than attempting to time trends, it relies on annual rebalancing (selling what grew, buying what fell) to return to target weights, accepting all market drawdowns in exchange for long-term simplicity.

Performance Comparison During Historical Crises

The critical difference between these two strategies lies in how they manage risk during extreme market events.

  • 2008 Financial Crisis: The 60/40 portfolio suffered a peak-to-trough drawdown of approximately -27% to -30% as equity markets collapsed. In contrast, GEM's absolute momentum filter rotated the entire portfolio to U.S. treasury and aggregate bonds early in the downturn, converting a major crash into a period of capital preservation.
  • 2020 COVID Crash: Because the COVID sell-off was extremely rapid (lasting less than a month before rebounding), GEM's 12-month lookback was too slow to transition to bonds before the market bottomed. GEM rode the crash down and rebounded similarly to a 60/40 portfolio, demonstrating that trend-following models can lag during short-duration "V-shaped" market panics.
  • 2022 Inflationary Bear Market: The year 2022 was unique because both stocks and bonds crashed simultaneously due to rapid rate hikes. The 60/40 portfolio had one of its worst years in history (-18.0%). GEM performed relatively better by moving to cash and short-term paper as absolute trends fell, avoiding a portion of the double bond/stock crash.

Side-by-Side Pros and Cons

GEM Strengths & Limits

  • Higher returns (12.3% CAGR vs 8.2%) 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.

Classic 60/40 Strengths & Limits

  • Extreme simplicity — only requires two ETFs (VTI and BND).
  • Very low transaction costs and minimal maintenance (rebalanced once a year).
  • Very tax-efficient — low turnover rate.
  • No downside protection; rides equity bear markets all the way down.
  • Vulnerable to periods where stocks and bonds correlate positively (e.g., 2022 inflation).

Which Strategy is Right For You?

Choose GEM if: You are comfortable with monthly monitoring, invest via tax-advantaged accounts (like IRAs or 401ks in the US, or tax-wrapped accounts in Europe), and want to maximize long-term growth while protecting capital from major multi-year bear markets.

Choose 60/40 if: You prefer a hands-off, "set and forget" approach, have a taxable investment account where frequent turnover triggers capital gains tax, and can emotionally tolerate drawdowns of 20-30% without panic-selling.

Frequently Asked Questions

Is GEM (Global Equity Momentum) better than a 60/40 portfolio?

Historically, GEM has outperformed the classic 60/40 portfolio on most risk-adjusted metrics. GEM achieved a historical CAGR of ~13.7% vs ~9.2% for 60/40, with a lower maximum drawdown (-22% vs -35%). The key difference is that GEM actively avoids bear markets by rotating to bonds when absolute momentum turns negative, while 60/40 stays fully invested in both stocks and bonds at all times — suffering full drawdowns during equity crashes.

What is the main risk of GEM compared to 60/40?

The main risks of GEM vs 60/40 are: (1) Whipsaw risk — GEM can generate false momentum signals in choppy markets, causing costly rotations. (2) Tracking error — GEM can significantly underperform the S&P 500 in strong bull markets when it is holding international stocks or bonds. (3) Behavioral risk — it requires monthly discipline to follow signals. The 60/40 portfolio is far simpler to implement and requires only annual rebalancing.

How does GEM vs 60/40 perform during recessions?

During the 2000–2002 dot-com crash, GEM's absolute momentum filter rotated to bonds, limiting losses to under -10%, while the 60/40 lost approximately -25%. During the 2007–2009 financial crisis, GEM again rotated to bonds, limiting drawdown to ~-22%, versus -35% for 60/40. However, in the March 2020 crash (fast and short), GEM did not rotate in time and experienced similar losses to 60/40 before recovering.

Which ETFs do I need to implement GEM vs 60/40 as a European investor?

For GEM (European UCITS): CSPX or VUSA (S&P 500), SWRD (MSCI World ex-US), AGGG (Aggregate Bonds). For classic 60/40: CSPX or VWRL (60% global stocks) + AGGG (40% bonds). GEM requires monthly signal checking and potential rebalancing, while 60/40 only needs annual rebalancing. StrategyIndex.io publishes monthly GEM signals on its Signals Dashboard.
