Common questions about these results

Are these live investor returns?

No. These are the latest model NAV results from the published backtest. A recent date alone does not make a result an independently observed live record. Investor costs, taxes and execution can differ.

Why can a strategy lag for a year?

A tactical model can hold defensive assets during a rally or change positions during reversals. A short window can differ substantially from its full history. Compare cumulative returns over matching dates and inspect drawdowns as well.

How long has it spent below a previous high?

Its last high-water mark was 2026-09-22, 9 days before 2026-10-01, and it is -1.23% below that level now. The longest run below a previous high in the full backtest was 2.9 years. Recovering from a drawdown can take years, and a strong trailing return does not mean a past high has been regained.

Where can I check the signals behind these results?

The Signals tab on this page lists each dated model decision for the selected variant; for Pro strategies they are visible to Pro members. The methodology page explains the backtest assumptions.

PAA (Protective Asset Allocation) — Tactical Asset Allocation Strategy

Protective Asset Allocation (PAA) by Keller & Keuning uses a breadth-based approach to determine how much of the portfolio should be in crash protection (bonds) vs. risky assets. It counts how many of the 12 universe assets have positive SMA(13) momentum, then computes a bond fraction that scales smoothly from 0% to 100% based on a configurable protection level. The risky portion is allocated equally across the top 6 assets ranked by momentum. This gradual scaling provides a smoother risk-on/risk-off transition than the binary VAA approach.
