No. An absolute valuation model does not exist. The value of the stock is a function of the investors buying and selling it. That being said, you can compare a value to what comparable companies are trading for, or what the company itself has historically traded at based on fundamentals.
It is like the housing market - you compare your house to your neighbors. The cost of the house is easily calculated but value is something intangible becuase 'beauty lies in the eyes of the beholder'.
Still, you can profitably trade using strategies that capitalize on growth trends, investor sentiment, etc. etc. You can even backtest these at places such as Portfolio123 (use code HKURTIS to get a 45 day free trial).
The tangible book value is the closest thing I can think of to value a company - but this is more closely related to bankruptcy value than it is trading value and future growth prospect. You figure this one out and you'll be a trillionaire.
