How to read these results
Method & calculation basis
New shares = old shares × numerator / denominator. Mechanical adjusted price = old price × denominator / numerator. A reverse split has numerator below denominator.
Coverage & limitations
The mechanical example assumes no market movement or fractional-share adjustment. Splitting shares does not itself create an investment return. Future splits are not predicted.
