The iM CAPE-MA35 ETF Rotation Strategy with 4 ETFs

  • This is a dynamic ETF allocation strategy using the CAPE-MA35 ratio—the Shiller CAPE divided by its 35-year moving average—to identify market phases and adjust portfolio exposure.
  • The model defines four primary phases with respective ETFs—Growth (QQQ), Defensive (GLD, XLU), Uptrend (QQQ, XLE), and Downtrend (GLD)—based on the trend and relative valuation of CAPE-MA35. ETF allocations are adjusted monthly in response to these phases.
  • Backtesting from 1999 to 2025 shows the model outperforms SPY with 20.1% annualized returns, lower drawdowns, and consistent long-term performance with low turnover.
  • The strategy offers a practical, rules-based approach to market timing, blending long-term valuation with trend analysis for superior risk-adjusted returns.
