Does anything beat buy & hold on HSBC?
Every setup we tested on HSBC — 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 0.98 did not clear the 1.28 selection hurdle (best-of-N luck cannot be ruled out). Buy-and-hold benchmark: +6.7% CAGR over 27.1 years (+14.6% CAGR in the out-of-sample window).

HSBC: The Best Setup Beat Buy-and-Hold — and Still Might Be Luck
HSBC lands in the awkward middle of our results. Of 749 indicator setups tested on HSBC, the strongest — Random Walk Index on the weekly timeframe — beat buy-and-hold in both the training and out-of-sample windows, adding +4.5% annual alpha against a buy-and-hold baseline of +6.7%. 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 0.98 came from 65 trades over 8.1 years, with a 41.5% win rate and a -37.9% maximum drawdown — a genuinely profitable record. But when you pick the best of 749 attempts, the winner is expected to look good by chance alone. Our selection hurdle for this asset is 1.28, and this setup did not clear it, so we cannot distinguish it from the luckiest of hundreds of tries. Only 7.9% 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.
Random Walk Index
Mechanical rule (exactly as backtested): Long while the bullish Random Walk Index exceeds the bearish one — trend vs noise. 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 0.98 · alpha +4.5% · 17 trades over 8.1 yrs.
Random Walk Index
Mechanical rule (exactly as backtested): Measures how far price travels versus a random walk — long while the up-walk dominates the down-walk. 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 0.98 · alpha +4.5% · 17 trades over 8.1 yrs.
ROC (20)
Mechanical rule (exactly as backtested): Variant — slow 20-period Rate of Change; long while positive. 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 0.97 · alpha +4.0% · 14 trades over 8.1 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 749 setups (indicator × parameters × timeframe) on HSBC. Only setups with ≥30 trades qualify (645 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 749 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 1.28 (√(2 ln N)/√T) AND positive alpha in both windows. Of the eligible setups, 7.9% had positive out-of-sample alpha (median OOS Sharpe 0.48) — the table below is truncated, but this summary covers all of them.
