Economic Profit Analysis

In the last post we calculated the opportunity cost for business that came around 12%.
Now by taking that opportunity cost as Cost of Capital we have calculated RoCE for companies of cement sector and by that RoCE we calculated which firm is earning in excess of cost of capital.
Here, attached is the excel file where analysis and all calculation is done.
By doing this activity we can filter good and bad companies up to some extent.
