Does anything beat buy & hold on Globe Life (GL)?
Every setup we tested on Globe Life (GL) — 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 0.88 did not clear the 0.98 selection hurdle (best-of-N luck cannot be ruled out). Buy-and-hold benchmark: +11.0% CAGR over 45.8 years (+12.7% CAGR in the out-of-sample window).

GL: The Best Setup Beat Buy-and-Hold — and Still Might Be Luck
Globe Life lands in the awkward middle of our results. Of 756 indicator setups tested on GL, the strongest — QQE on the weekly timeframe — beat buy-and-hold in both the training and out-of-sample windows, adding +5.9% annual alpha against a buy-and-hold baseline of +11.0%. 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 0.88 came from 130 trades over 13.8 years, with a 53.8% win rate and a -63.4% maximum drawdown — a genuinely profitable record. But when you pick the best of 756 attempts, the winner is expected to look good by chance alone. Our selection hurdle for this asset is 0.98, and this setup did not clear it, so we cannot distinguish it from the luckiest of hundreds of tries. Only 0.4% of setups beat buy-and-hold at all. Regimes shift, and past performance predicts nothing about what comes next.

Top setups as mechanical rules
Exactly as the backtest defined them — no discretionary steps, no hidden filters.
QQE
Mechanical rule (exactly as backtested): Quantitative Qualitative Estimation — smoothed RSI with an ATR-of-RSI trailing band. 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 0.88 · alpha +5.9% · 39 trades over 13.8 yrs.
DeMarker
Mechanical rule (exactly as backtested): Buy DeMarker up through 0.3, exit above 0.7 — a demand/supply gauge. 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 0.82 · alpha -3.0% · 40 trades over 13.7 yrs.
Tweezer Bottom
Mechanical rule (exactly as backtested): Bullish reversal - two candles sharing nearly the same low, the second one green. 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 0.82 · alpha -6.5% · 24 trades over 13.8 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 756 setups (indicator × parameters × timeframe) on Globe Life (GL). Only setups with ≥30 trades qualify (713 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 756 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, 0.4% had positive out-of-sample alpha (median OOS Sharpe 0.29) — the table below is truncated, but this summary covers all of them.
