Does anything beat buy & hold on China Internet?

Every setup we tested on China Internet — 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 only beat buy-and-hold in one window — a regime artifact, not a strategy. Buy-and-hold benchmark: +1.1% CAGR over 13.0 years (-2.1% CAGR in the out-of-sample window).

China Internet: Nothing Beat Buy-and-Hold, and That Is the Honest Answer

Broad, diversified instruments like China Internet are where indicator strategies go to disappoint. We ran 726 setups against KWEB, and none cleared the bar once scored honestly — on data the strategy never saw. The best of the batch, MA Envelope on the weekly timeframe, posted an out-of-sample Sharpe of 0.71, short of the 1.84 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 +1.1% annualized return as the number nothing here managed to beat.

Read these figures with the selection problem in mind. Test 726 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 37.1% of setups outperformed buy-and-hold even in-sample, and the top candidate produced +20.8% annual alpha over 3.9 unseen years, across 32 trades with a 62.5% win rate and a -70.4% 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.

Nothing here earned a verdict — these are the best of a losing field, published so you can see exactly how "best" still failed.

#1 · Mean Reversion · Weekly

MA Envelope

Mechanical rule (exactly as backtested): Percent envelope around an EMA — buy the dip below the lower band, exit back at the mean. Signals are evaluated at weekly-bar close, the position changes on the NEXT bar, 0.08% cost per side, long/flat only — no leverage, no shorting.

Keltner Mean-Reversion

Mechanical rule (exactly as backtested): Buy the lower Keltner band (20,2), exit back at the EMA basis. Signals are evaluated at daily-bar close, the position changes on the NEXT bar, 0.08% cost per side, long/flat only — no leverage, no shorting.

Predictive Ranges

Mechanical rule (exactly as backtested): ATR-stepped adaptive average + range bands — long while price holds above a rising predictive average. Signals are evaluated at daily-bar close, the position changes on the NEXT bar, 0.08% cost per side, long/flat only — no leverage, no shorting.

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

We tested 726 setups (indicator × parameters × timeframe) on China Internet. Only setups with ≥30 trades qualify (512 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 726 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 1.84 (√(2 ln N)/√T) AND positive alpha in both windows. Of the eligible setups, 37.1% had positive out-of-sample alpha (median OOS Sharpe -0.02) — the table below is truncated, but this summary covers all of them.
