Does anything beat buy & hold on Smurfit Westrock (SW)?

Every setup we tested on Smurfit Westrock (SW) — 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.

MIXED

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 1.33 did not clear the 1.56 selection hurdle (best-of-N luck cannot be ruled out). Buy-and-hold benchmark: +12.0% CAGR over 17.9 years (+0.9% CAGR in the out-of-sample window).

SW: The Best Setup Beat Buy-and-Hold — and Still Might Be Luck

Smurfit Westrock lands in the awkward middle of our results. Of 739 indicator setups tested on SW, the strongest — Pivot Points (Standard) on the daily timeframe — beat buy-and-hold in both the training and out-of-sample windows, adding +44.4% annual alpha against a buy-and-hold baseline of +12.0%. For an individual stock, that matters less than it sounds. Single names run on earnings surprises, management turnover, and idiosyncratic shocks that no historical pattern is obliged to survive. A setup that worked here worked on one company's history, once — and the companies whose histories ended badly aren't in anyone's backtest.

The honest read: the out-of-sample Sharpe of 1.33 came from 422 trades over 5.4 years, with a 54.3% win rate and a -66.9% maximum drawdown — a genuinely profitable record. But when you pick the best of 739 attempts, the winner is expected to look good by chance alone. Our selection hurdle for this asset is 1.56, and this setup did not clear it, so we cannot distinguish it from the luckiest of hundreds of tries. Only 8.0% of setups beat buy-and-hold at all. Regimes shift, and past performance predicts nothing about what comes next.

Every figure above is computed from our own backtests — nothing is estimated or invented. Hypothetical results; not investment advice.

The rules

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.

#1 · Mean Reversion · Daily

Pivot Points (Standard)

What it is: A market-structure rule: it reacts to swing structure and prior levels rather than to a smoothed average. 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.

VWAP Bands

What it is: A channel / envelope rule: it measures how far price has travelled from a moving reference and acts at the extremes. 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.

Fibonacci Pivots

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

We tested 739 setups (indicator × parameters × timeframe) on Smurfit Westrock (SW). Only setups with ≥30 trades qualify (578 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 739 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 1.56 (√(2 ln N)/√T) AND positive alpha in both windows. Of the eligible setups, 8.0% had positive out-of-sample alpha (median OOS Sharpe -0.42) — 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.
