Based on financial statements, the key value drivers including growth rate of Net Operating Profit Less Adjusted Taxes (NOPLAT), Return On Invested Capital (ROIC), Weighted Average Cost of Capital (WACC), etc are calculated. With those, plus the reasonable expectation on the mid and long-term performance, a due stock price is suggested as the measure for the value of a company. Users can create their own valuations by changing the key values, using their own information and assumptions about the company’s future performance.
