This is Exhibit A why data vendors should not try to provide “adjusted” data, since they are unlikely to ever do it right. They should just provide point-in-time historical data without touching anything.

IBM had a spin-off of 0.2 shares KD per IBM on 11/4/2021.

So the “adjustment” logic saw 0.2 and blindly scaled data before that date by 0.2.
