Plain Sharpe
Measures the selected series but does not know how many alternatives were discarded.
VALIDATE / MULTIPLE TESTING
Every new trial makes an attractive Sharpe less surprising.
DSR helps distinguish rare quality from the expected winner of a large search and stays beside the complete trial history.

Plain Sharpe
Measures the selected series but does not know how many alternatives were discarded.
- 02
Trial count
More trials raise the benchmark the selected candidate needs to exceed.
- 03
Distribution shape
Skew and kurtosis affect confidence in the observed Sharpe.
- 04
Method boundary
DSR does not prove an economic mechanism or replace holdout and walk-forward.

DECISION FRAMEWORK
Which independent test could still reject the candidate?
Treat holdout, time stability, multiple-testing correction and stress paths as separate evidence. Agreement matters more than one green metric.

Validation verdict
Important
Historical, statistical and model results do not promise future returns. kquant provides computational tools and technical execution, but does not assess whether a specific trade is suitable for a user.
