On the bench
Rules waiting to be tested. Each gets the same treatment: replicate the claim, then stress it.

How we test
Each rule is rebuilt from the original post, run on split- and dividend-adjusted daily closes, and compared with the obvious alternatives over the same dates and timing. We report the viral window and the long history, the effect of one-day-later execution and costs, and the caveats that come with a hindsight-picked universe.
Once a strategy is live, its record starts on launch day and is never edited. Signals go out by email once a month, after the close.
