STT: we tested 757 setups and none beat simply holding State Street Corporation
For State Street Corporation (STT), we ran 757 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, LSMA 10/30 Cross on the daily timeframe, ranked at the top in-sample but delivered an out-of-sample Sharpe of 0.9, short of our hurdle of 0.98. Buy-and-hold returned +17.4% 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 757 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. LSMA 10/30 Cross managed 0.9, with out-of-sample alpha of +4.3% across 13.9 years and 482 trades, and only 0.3% 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.
LSMA 10/30 Cross
Mechanical rule (exactly as backtested): MA variant — least-squares MA cross; long while fast leads slow. 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 0.9 · alpha +4.3% · 141 trades over 13.9 yrs.
Chaikin Volatility
Mechanical rule (exactly as backtested): Chaikin's high-low range expansion — long on expanding volatility within 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.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.76 · alpha -2.8% · 54 trades over 13.9 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 0.74 · alpha -0.3% · 47 trades over 13.9 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 2026-07-02. Currently FLAT.
We tested 757 setups (indicator × parameters × timeframe) on State Street Corporation (STT). Only setups with ≥30 trades qualify (703 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 757 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, 0.3% had positive out-of-sample alpha (median OOS Sharpe 0.29) — the table below is truncated, but this summary covers all of them.
