Does anything beat buy & hold on L3Harris (LHX)?

Every setup we tested on L3Harris (LHX) — 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: +10.9% CAGR over 44.6 years (+17.6% CAGR in the out-of-sample window).

LHX: we tested 764 setups and none beat simply holding L3Harris

For L3Harris (LHX), we ran 764 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, Volatility Regime (VIX-style) on the weekly timeframe, ranked at the top in-sample but delivered an out-of-sample Sharpe of 0.85, short of our hurdle of 1.0. Buy-and-hold returned +10.9% 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 764 setups and keep the best one, something will always look impressive by chance alone. That is why we require the survivor to clear 1.0 out of sample. Volatility Regime (VIX-style) managed 0.85, with out-of-sample alpha of -6.8% across 13.4 years and 73 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.

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.

#1 · Regime · Weekly

Volatility Regime (VIX-style)

Mechanical rule (exactly as backtested): Risk-on filter - long only in a calm volatility regime (20-bar realized vol below its 100-bar median) and an uptrend. 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.

Historical Volatility Regime

Mechanical rule (exactly as backtested): Annualized return volatility regime — long in low-volatility uptrends. 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.

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

We tested 764 setups (indicator × parameters × timeframe) on L3Harris (LHX). Only setups with ≥30 trades qualify (718 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 764 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 1.0 (√(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 0.47) — the table below is truncated, but this summary covers all of them.
