Global Growth Cycle Enhanced Momentum (Link)

Fetch 17-country CLI panel from OECD SDMX (or FRED fallback). Compute diffusion = share of countries where CLI[t] > CLI[t-1]. Backtest max drawdown: -20.9%.

Data caveat: this backtest uses revised macro data

This strategy's risk regime comes from the OECD Composite Leading Indicator, which is revised every month after first publication. The backtest on this page uses today's revised values. We replayed the strategy against the data as it was originally published, back to 2006: the regime call differs in 42 of 231 months, Sharpe drops from 1.31 to 0.84, and the worst drawdown deepens from -19% to -34%. The 2008 defense holds up on first prints; the 2020 sidestep does not, and exists only in revised data. On as-published data the strategy still beats the index on Sharpe and drawdown, but by far less than this card implies. Live signals use first publications, so the as-published profile is the better guide to forward expectations.

Fetch 17-country CLI panel from OECD SDMX (or FRED fallback); Compute diffusion = share of countries where CLI[t] > CLI[t-1]; Apply 1-month publication lag (OECD releases ~12th of next month); Regime: diffusion >= 50% → risk-on; else…

Before these dates the backtest uses a stand-in, not the fund itself, so the results over those stretches show how the rules would have behaved, not what the fund returned.

Is Global Growth Cycle Enhanced Momentum (Link) still working in 2026?

Global Growth Cycle Enhanced Momentum (Link) returned 4.55% over the trailing 12 months and 33.42% over 36 months through 2026-10-22, compared with a full-backtest annualized return of 15.05%. Its full-backtest maximum drawdown was -20.95%. The full sample contains 10618 daily NAV observations from 1985-01-01. These are model results, not investor account returns or a promise. As of 2026-10-22 it is -11.02% below its high-water mark of 2026-02-25, 8 months ago, and its longest run below a previous high was 2.1 years. Recent returns do not establish that the strategy will keep working.

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 2026-02-25, 8 months before 2026-10-22, and it is -11.02% below that level now. The longest run below a previous high in the full backtest was 2.1 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.

Real-time data check

The OECD revises every country's CLI history each month, so a backtest on today's data quietly uses information that was not available at the time. We replayed this strategy against the OECD's own publication archive (239 monthly editions, all 17 countries, back to 2006) on the same engine and costs as the card. Same strategy, two data realities:

Card (revised data)As published (real time)2007-06-30 .. 2026-09-30, growth of 100
34058482910732008201020122014201620182020202220242026rode the 2020 crash (-34%)revised 1189as published 691
GGCEM on revised versus as-published OECD data, 2007-06-30 .. 2026-09-30
Card (revised)As publishedSPY buy & hold
CAGR13.8%10.6%10.9%
Sharpe1.310.840.66
Worst drawdown (daily)-18.8%-33.7%-55.2%

The answer differs by crisis. On as-published data the regime call differed in 42 of 231 months. The 2008 defense was genuine: real-time signals sat risk-off from September 2007 through April 2009 and the strategy gained 16% while the index fell 38%. The 2020 sidestep was not: first prints stayed risk-on and the strategy rode the crash down, which is the drawdown marked above. The 2022 bond defense was genuine in both data sets. Over the whole window as-published returns land just below SPY while keeping a better Sharpe and roughly 21 points less peak drawdown, so the edge is real but far smaller than the card implies. Live signals use first publications, so the as-published column is the better guide to what this strategy does going forward.

Method: the OECD real-time publication archive (DSD_STES_REVISIONS, monthly editions from 2006-04) for all 17 CLI countries, production diffusion computation and publication lag, production backtest engine, 10 bps costs. Sharpe ratios on monthly returns above cash, as on the card, restated 2026-10-20. Cross-checked against the St. Louis Fed ALFRED vintages wherever the two overlap.

Global Growth Cycle Enhanced Momentum (Link) — Tactical Asset Allocation Strategy

Global Growth Cycle Enhanced Momentum (GGCEM) is Grzegorz Link's enhanced variant of the Global Growth Cycle strategy, tracked by major TAA services. It combines a macro regime filter (OECD Composite Leading Indicator) with 12-month relative momentum inside each regime.

During expansionary periods (OECD CLI rising), the strategy allocates 100% to the stronger of SPY (US equities) and IEFA (international developed equities) based on 12-month total return. During contractionary periods (OECD CLI falling), the strategy rotates to the stronger of AGG (US aggregate bonds) and BIL (1-3 month T-bills, cash proxy), a dynamic bond vs cash gate that protects against rising-rate environments where long bonds sell off alongside equities.
