Does anything beat buy & hold on Siren (SIREN)?
Every setup we tested on Siren (SIREN) — 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 1.57 did not clear the 4.05 selection hurdle (best-of-N luck cannot be ruled out). Buy-and-hold benchmark: -16.3% CAGR over 2.2 years (-99.2% CAGR in the out-of-sample window).

Siren (SIREN): Beat Buy-and-Hold in Both Windows, Couldn't Beat the Selection Hurdle
Crypto sets a brutal baseline: Siren compounds at -16.3% annualized just for holding, and it charges drawdowns near -65.6% for the privilege. Against that backdrop we ran 313 indicator configurations on SIREN. The best of them — Fisher Transform on the daily timeframe — beat buy-and-hold in both the training and holdout windows, with a profitable out-of-sample trade profile across 55 trades. That is genuinely uncommon here. But 'best of 313' is exactly the phrase that should make you slow down, which is what the second paragraph is for.
When you pick the winner from 313 attempts, the result is partly signal and partly luck of the draw. Our hurdle corrects for that: with this many tries and 0.7 years of holdout data, an out-of-sample Sharpe needs to clear 4.05 before we trust it. This one landed at 1.57 — 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.
Every figure above is computed from our own backtests — nothing is estimated or invented. Hypothetical results; not investment advice.
The setups that ranked, and what they are
Fully mechanical — no discretionary steps, no hidden filters. We name the indicator and publish its record; we keep the settings.
Fisher Transform
What it is: An oscillator rule: it reads a bounded momentum gauge and takes exposure when it turns from an extreme. Long/flat only — no leverage, no shorting. The parameters we tested are not published.
How it was tested: signals evaluated at daily-bar close, the position changes on the NEXT bar, 0.08% cost per side. Same engine, same cost model, same out-of-sample split as every other number on this site.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 1.57 · alpha +351.5% · 18 trades over 0.7 yrs.

Since publication — including if it loses
Buy-and-hold is ahead so far — we publish that too. That is the point. Marked to market nightly from real prices, rules frozen at publication, as of 2026-10-27. Currently LONG.
We tested 313 setups (indicator × parameters × timeframe) on Siren (SIREN). Only setups with ≥30 trades qualify (122 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 313 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 4.05 (√(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 -0.36) — the table below is truncated, but this summary covers all of them. How we test: methodology. The scoring contract is published in full; the parameters of each individual setup are not.
