Does anything beat buy & hold on 3x S&P Bear?
Every setup we tested on 3x S&P Bear — 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.
No setup beat simply holding once tested honestly. We say so plainly.
Its best setup's out-of-sample profit factor (0.81) is below 1 — it lost money per trade on unseen data. Buy-and-hold benchmark: -42.4% CAGR over 17.0 years (-34.1% CAGR in the out-of-sample window).

3x S&P Bear: Nothing Beat Buy-and-Hold, and That Is the Honest Answer
Broad, diversified instruments like 3x S&P Bear are where indicator strategies go to disappoint. We ran 664 setups against SPXU, and none cleared the bar once scored honestly — on data the strategy never saw. The best of the batch, Bullish Harami on the daily timeframe, posted an out-of-sample Sharpe of 0.54, short of the 1.6 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 -42.4% annualized return as the number nothing here managed to beat.
Read these figures with the selection problem in mind. Test 664 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 99.2% of setups outperformed buy-and-hold even in-sample, and the top candidate produced +42.8% annual alpha over 5.1 unseen years, across 127 trades with a 37.0% win rate and a -55.7% 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.
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.
Bullish Harami
Mechanical rule (exactly as backtested): Bullish reversal - a small green candle whose body sits inside a larger prior red candle. 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.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.54 · alpha +42.8% · 38 trades over 5.1 yrs.
LSMA 200 Trend
Mechanical rule (exactly as backtested): VARIANT — price above a rising LSMA(200). 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.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.06 · alpha +29.9% · 25 trades over 5.1 yrs.
Inverse Fisher RSI
Mechanical rule (exactly as backtested): Ehlers' Inverse Fisher Transform of RSI — sharp ±1 momentum; long while positive. 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.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.06 · alpha +29.1% · 37 trades over 5.1 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 2026-07-02. Currently FLAT.
We tested 664 setups (indicator × parameters × timeframe) on 3x S&P Bear. Only setups with ≥30 trades qualify (506 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 664 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 1.6 (√(2 ln N)/√T) AND positive alpha in both windows. Of the eligible setups, 99.2% had positive out-of-sample alpha (median OOS Sharpe -0.46) — the table below is truncated, but this summary covers all of them.
