Sorry that was CHKE not CPLA

I am looking at CPLA currently closed at 10.00, 52 week low on the app is 10.65

Here is the explanation behind it all:

But unfortunately, not why the stock is still on the action and trifecta lists.

Also the defunct ticker ADVCD is still showing up on the top 12 trifecta companies on the online app.

On further research Avant-E which used to be ADVCD is now listed as ADVC, but no longer is a top 20 action stock. There still seems to be a problem with delisting or relisted defunct ticker still making it into the universe, which they should not be, since they are not investable or trackable.

Is the filtered universe the Action score list that you backtested? Or did you actually back test the Trifecta score?
