- Decide whether or not the share change is a rise or a lower. It will make it easier to determine whether or not to subtract or add the share to the unique worth.
-
If the share change is a rise, calculate the change by taking a proportion of the unique worth. That is usually represented as a constructive proportion, and we add this to the unique worth. For instance:
proportion change = (modified worth – authentic worth) / authentic worth * 100
-
If the share change is a lower, calculate the change by subtracting a proportion from the unique worth. That is usually represented as a destructive proportion, and we subtract this from the unique worth. For instance:
proportion change = (authentic worth – modified worth) / authentic worth * 100
