Does anything beat buy & hold on Beldex (BDX)?
Every setup we tested on Beldex (BDX) — 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.
Beat buy-and-hold in both windows — but can't be told apart from selection luck.
Beat buy-and-hold in both the full window and out-of-sample but its OOS Sharpe 1.64 did not clear the 2.48 selection hurdle (best-of-N luck cannot be ruled out). Buy-and-hold benchmark: +1.0% CAGR over 7.0 years (+43.5% CAGR in the out-of-sample window).

Beldex (BDX): Beat Buy-and-Hold in Both Windows, Couldn't Beat the Selection Hurdle
Crypto sets a brutal baseline: Beldex compounds at +1.0% annualized just for holding, and it charges drawdowns near -57.7% for the privilege. Against that backdrop we ran 637 indicator configurations on BDX. The best of them — Disparity (5) on the weekly timeframe — beat buy-and-hold in both the training and holdout windows, with a profitable out-of-sample trade profile across 39 trades. That is genuinely uncommon here. But 'best of 637' is exactly the phrase that should make you slow down, which is what the second paragraph is for.
When you pick the winner from 637 attempts, the result is partly signal and partly luck of the draw. Our hurdle corrects for that: with this many tries and 2.1 years of holdout data, an out-of-sample Sharpe needs to clear 2.48 before we trust it. This one landed at 1.64 — profitable, but statistically indistinguishable from the luckiest of hundreds of tries. Add that crypto structure keeps changing — new venues, new participants, shifting volatility regimes — and a pattern from the past has no obligation to repeat. Treat this as a research lead, not an edge.

Top setups as mechanical rules
Exactly as the backtest defined them — no discretionary steps, no hidden filters.
Disparity (5)
Mechanical rule (exactly as backtested): Variant — fast disparity index (price vs EMA5); long while positive. 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 1.64 · alpha +13.0% · 12 trades over 2.1 yrs.
Rainbow MA
Mechanical rule (exactly as backtested): Recursively-smoothed rainbow of 10 moving averages - long while price is above the rainbow's 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.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 1.56 · alpha +9.8% · 10 trades over 2.1 yrs.
Connors RSI
Mechanical rule (exactly as backtested): Connors' composite RSI (price + streak) — buy below 20, exit above 70. 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 1.53 · alpha +9.3% · 37 trades over 3.0 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 LONG.
We tested 637 setups (indicator × parameters × timeframe) on Beldex (BDX). Only setups with ≥30 trades qualify (366 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 637 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 2.48 (√(2 ln N)/√T) AND positive alpha in both windows. Of the eligible setups, 3.6% had positive out-of-sample alpha (median OOS Sharpe 0.51) — the table below is truncated, but this summary covers all of them.
