Does anything beat buy & hold on Paccar (PCAR)?

Every setup we tested on Paccar (PCAR) — 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.

NOTHING BEAT BUY-AND-HOLD

No setup beat simply holding once tested honestly. We say so plainly.

Its best setup trailed buy-and-hold out-of-sample. Buy-and-hold benchmark: +14.8% CAGR over 46.4 years (+15.1% CAGR in the out-of-sample window).

PCAR: we tested 759 setups and none beat simply holding Paccar

For Paccar (PCAR), we ran 759 indicator configurations against a plain buy-and-hold benchmark, and none of them earned the right to replace it. Individual stocks carry idiosyncratic risk — earnings surprises, guidance changes, sector rotation — that indicators built on price history cannot see coming. The best-looking setup, Schaff Trend Cycle on the weekly timeframe, ranked at the top in-sample but delivered an out-of-sample Sharpe of 1.07, short of our hurdle of 0.98. Buy-and-hold returned +14.8% annualized over the test period; the top strategies mostly captured pieces of that same move while adding trading friction.

How to read this honestly: when you test 759 setups and keep the best one, something will always look impressive by chance alone. That is why we require the survivor to clear 0.98 out of sample. Schaff Trend Cycle managed 1.07, with out-of-sample alpha of -8.6% across 13.9 years and 77 trades, and only 0.0% of everything we tested beat the benchmark on unseen data — roughly what luck would produce. None of this predicts anything: the regime that generated these numbers can shift, and single stocks shift faster than most. Treat this page as a record of what failed under honest testing, not a forecast.

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

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

We tested 759 setups (indicator × parameters × timeframe) on Paccar (PCAR). Only setups with ≥30 trades qualify (723 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 759 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 0.98 (√(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 0.29) — the table below is truncated, but this summary covers all of them.
