Rule / approach
1. Fetch 17-country CLI panel from OECD SDMX (or FRED fallback) 2. Compute diffusion = share of countries where CLI[t] > CLI[t-1] 3. Apply 1-month publication lag (OECD releases ~12th of next month) 4. Regime: diffusion >= 50% → risk-on…

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 (2018 onward, the span where real publication archives exist): the regime call differs in 19% of months, Sharpe drops from 1.19 to 0.82, the worst drawdown deepens from -11% to -34%, and the 2020 crash sidestep exists only in revised data. Live signals use first publications, so the as-published profile is the better guide to forward expectations.

Full comparison in the real-time data check below. This strategy is excluded from our Top Performers rankings while the data review is open.

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 actual publication archive (ALFRED real-time vintages, all 17 countries, first archive mid-2018) on the same engine and costs as the card. Same strategy, two data realities:

Card (revised data)As published (real time)2019-09-30 .. 2026-08-31, growth of 100
1111451792132020202120222023202420252026rode the 2020 crash (-34%)revised 223as published 237
GGCEM on revised versus as-published OECD data, 2019-09-30 .. 2026-08-31

CAGR12.4%13.4%15.2%
Sharpe1.190.820.83
Worst drawdown (daily)-11.4%-33.7%-33.7%

The return survives, the risk story does not: on as-published data the regime call differed in 18 of 96 months, the strategy held equities straight through the 2020 crash, and its risk-adjusted profile matched plain SPY. The 2022 bond defense was genuine in both data sets. Live signals use first publications, so the as-published column is the better guide to what this strategy does going forward. History before 2018 cannot be checked this way because no publication archive exists.

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.
