CVS: we tested 753 setups and none beat simply holding CVS Health
For CVS Health (CVS), we ran 753 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, Money Flow Index on the daily timeframe, ranked at the top in-sample but delivered an out-of-sample Sharpe of 0.63, short of our hurdle of 0.91. Buy-and-hold returned +9.7% 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 753 setups and keep the best one, something will always look impressive by chance alone. That is why we require the survivor to clear 0.91 out of sample. Money Flow Index managed 0.63, with out-of-sample alpha of -1.5% across 16.1 years and 55 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.
Money Flow Index
What it is: An oscillator rule: it reads a bounded momentum gauge and takes exposure when it turns from an extreme. Long/flat only — no leverage, no shorting. The parameters we tested are not published.
How it was tested: signals evaluated at daily-bar close, the position changes on the NEXT bar, 0.08% cost per side. Same engine, same cost model, same out-of-sample split as every other number on this site.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.63 · alpha -1.5% · 17 trades over 16.1 yrs.
Inside-Bar Breakout
What it is: A breakout rule: it waits for price to clear a prior range and rides the expansion until it fails. Long/flat only — no leverage, no shorting. The parameters we tested are not published.
How it was tested: signals evaluated at daily-bar close, the position changes on the NEXT bar, 0.08% cost per side. Same engine, same cost model, same out-of-sample split as every other number on this site.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.63 · alpha -4.4% · 95 trades over 16.1 yrs.
Trend-Gated Asymmetric
What it is: A momentum rule: it holds while rate-of-change stays positive and steps aside when it rolls over. Long/flat only — no leverage, no shorting. The parameters we tested are not published.
How it was tested: signals evaluated at weekly-bar close, the position changes on the NEXT bar, 0.08% cost per side. Same engine, same cost model, same out-of-sample split as every other number on this site.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.6 · alpha -2.4% · 16 trades over 16.2 yrs.
Since publication — including if it loses
Buy-and-hold is ahead so far — we publish that too. That is the point. Marked to market nightly from real prices, rules frozen at publication, as of 2026-10-26. Currently FLAT.
We tested 753 setups (indicator × parameters × timeframe) on CVS Health (CVS). Only setups with ≥30 trades qualify (714 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 753 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 0.91 (√(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 0.24) — the table below is truncated, but this summary covers all of them. How we test: methodology. The scoring contract is published in full; the parameters of each individual setup are not.
