Lab research — Tradour

What we tested

From 2025 onward, how often did Entertainment observations match the frozen opposite-displayed direction rule?

The specification was frozen before this run. Neutral and unevaluated cases do not enter the directional success-rate denominator.

What we found

62.1% matched the frozen rule.

18 matched and 11 did not, from 29 directional cases.

Eligible observations: 35
Distinct tickers: 7
Evidence period: 21 Jan 2025 – 7 Aug 2026

How strong is the evidence?

Keep the range beside the headline.

The 95% Wilson interval is 44% to 77.3%. The archive was already exposed, so this is not a clean holdout result.

What this does not prove

A useful historical result is not a trading instruction.

The outcome is the frozen rule-aligned legacy directional result, not a canonical market return.
This archive was available before the Lab test was registered, so the result is exploratory rather than clean out-of-sample evidence.
Repeated tickers and shared market events may reduce the effective sample size.

What could we test next?

Fork the question; never rewrite this result.

A variation becomes a new frozen research object linked back to this study.
