1. Choose peer companies for IBM and download their relevant financial data. You don't have to download entire financial statements ? only the items used in multiples valuation
2. Using approach similar to the one described in this module's Excel file, find valuation multiples (ratios) of peer companies.
3. Estimate your company's equity value and enterprise value

I suggest starting from the "Multiples Valuation Template" in Module 4 Excel file and adjust it accordingly

I could not upload the excel.
