Does anything beat buy & hold on Core Emerging (IEMG)?

Every setup we tested on Core Emerging (IEMG) — ranked out-of-sample, corrected for multiple testing, and forward-tracked in public from the day this page published. The honest answer is the headline.

NOTHING BEAT BUY-AND-HOLD

No setup beat simply holding once tested honestly. We say so plainly.

Its best setup trailed buy-and-hold out-of-sample. Buy-and-hold benchmark: +6.2% CAGR over 13.7 years (+14.5% CAGR in the out-of-sample window).

Core Emerging: Nothing Beat Buy-and-Hold, and That Is the Honest Answer

Broad, diversified instruments like Core Emerging are where indicator strategies go to disappoint. We ran 732 setups against IEMG, and none cleared the bar once scored honestly — on data the strategy never saw. The best of the batch, Demand Index on the weekly timeframe, posted an out-of-sample Sharpe of 1.14, short of the 1.79 hurdle we require before calling anything real. For an index fund this is the expected result: whatever inefficiency exists in single names tends to average away in the basket, leaving buy-and-hold's +6.2% annualized return as the number nothing here managed to beat.

Read these figures with the selection problem in mind. Test 732 indicators, keep the best, and the winner looks impressive by construction — which is exactly why the hurdle exists instead of applause for a lucky draw. Here, only 0.0% of setups outperformed buy-and-hold even in-sample, and the top candidate produced -2.3% annual alpha over 4.1 unseen years, across 31 trades with a 67.7% win rate and a -34.7% drawdown. That pattern reads as noise, not signal. Markets also change, so even a genuine past edge can fade. This page documents what failed — useful to know before assuming something works.

Every figure above is computed from our own backtests — nothing is estimated or invented. Hypothetical results; not investment advice.

How this verdict was computed (mode: out-of-sample)

We tested 732 setups (indicator × parameters × timeframe) on Core Emerging (IEMG). Only setups with ≥30 trades qualify (540 did). Setups are ranked by out-of-sample Sharpe — the last ~30% of history, which standard-parameter rules never saw during selection. Because picking the best of 732 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 1.79 (√(2 ln N)/√T) AND positive alpha in both windows. Of the eligible setups, 0.0% had positive out-of-sample alpha (median OOS Sharpe 0.37) — the table below is truncated, but this summary covers all of them.
