This is a simple model which aims to value US listed stocks using equity risk premiums. The model provides a range of valuations based on a market environment ranging from exuberance (Exit Value) to despair (Bottom Fishing Value).
And yes, you can input stock symbols on the model to get a view on most US listed stocks. And you can over ride the consensus EPS estimate to generate a value based on your perception of forward EPS.
