Does anything beat buy & hold on Semiconductors (SOXX)?
Every setup we tested on Semiconductors (SOXX) — 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.

Semiconductors: Nothing Beat Buy-and-Hold, and That Is the Honest Answer
Broad, diversified instruments like Semiconductors are where indicator strategies go to disappoint. We ran 749 setups against SOXX, and none cleared the bar once scored honestly — on data the strategy never saw. The best of the batch, Fractal Adaptive MA on the weekly timeframe, posted an out-of-sample Sharpe of 1.32, short of the 1.33 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 +14.1% annualized return as the number nothing here managed to beat.
Read these figures with the selection problem in mind. Test 749 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 -8.7% annual alpha over 7.5 unseen years, across 160 trades with a 54.4% win rate and a -66.0% 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.

The least-bad setups — shown with their failure numbers
Nothing here earned a verdict — these are the best of a losing field, published so you can see exactly how "best" still failed.
Fractal Adaptive MA
Mechanical rule (exactly as backtested): Long while price is above Ehlers' Fractal Adaptive MA (adapts to fractal dimension). 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.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 1.32 · alpha -8.7% · 43 trades over 7.5 yrs.
Volume-Weighted EMA
Mechanical rule (exactly as backtested): MA variant — EMA weighted by volume; long above a rising line. 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.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 1.27 · alpha -4.1% · 20 trades over 7.5 yrs.
Price Volume Trend
Mechanical rule (exactly as backtested): Long while the Price Volume Trend line is above its 21-EMA. 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.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 1.26 · alpha -6.6% · 17 trades over 7.5 yrs.
Since publication — including if it loses
The forward record is just getting started — the gap between the two is the honest score. Marked to market nightly from real prices, rules frozen at publication, as of 2026-06-29. Currently FLAT.
We tested 749 setups (indicator × parameters × timeframe) on Semiconductors (SOXX). Only setups with ≥30 trades qualify (642 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 749 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 1.33 (√(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 0.77) — the table below is truncated, but this summary covers all of them.
