- Stock valuation
There are several methods used to value companies and their stocks. They attempt to give an estimate of their

fair value , by using fundamental economic criteria. This theoretical valuation has to be perfected with market criteria, as the final purpose is to determine**potential market prices**.**Fundamental criteria (fair value)**The most theoretically sound

**stock valuation method**, called income valuation or thediscounted cash flow (**DCF**) method, involves**discounting of the profits**(dividends, earnings, or cash flows) the stock will bring to the stockholder in the foreseeable future, and a final value on disposition.Fact|date=July 2008 The discounted rate normally includes arisk premium which is commonly based on thecapital asset pricing model .**Approximate valuation approaches****Average growth approximation**: Assuming that two stocks have the sameearnings growth , the one with a lowerP/E is a better value. TheP/E method is perhaps the most commonly used valuation method in the stock brokerage industry.Fact|date=July 2008 By using comparison firms, a target price/earnings (or P/E) ratio is selected for the company, and then the future earnings of the company are estimated. The valuation's fair price is simply estimated earnings times target P/E. This model is essentially the same model as Gordon's model, if k-g is estimated as the dividend payout ratio (D/E) divided by the target P/E ratio.**Constant growth approximation**: TheGordon model or "Gordon's growth model"Corporate Finance, Stephen Ross, Randolph Westerfield, and Jeffery Jaffe, Irwin, 1990, pp. 115-130.] is the best known of a class ofdiscounted dividend model s. It assumes that dividends will increase at a constant growth rate (less than the discount rate) forever. The valuation is given by the formula::$P\; =\; Dcdotsum\_\{i=1\}^\{infty\}left(frac\{1+g\}\{1+k\}\; ight)^\{i\}\; =\; Dcdotfrac\{1+g\}\{k-g\}$ .

This is probably the most rigorous approximation that is practical [*[*] .*http://www.moneychimp.com/articles/valuation/dcf.htm Discounted Cash Flow Calculator for Stock Valuation*]While these DCF models are commonly used, the uncertainty in these values is hardly ever discussed. Note that the models diverge for $k=g$and hence are extremely sensitive to the difference of dividend growth to discount factor. One might argue that an analyst can justify any value (and thatwould usually be one close to the current price supporting his call) by fine-tuning the growth/discount assumptions.

**Market criteria (potential price)**Some feel that if the stock is listed in a well organized stock market, with a large volume of transactions, the listed price will be close to the estimated fair value.Fact|date=July 2008 This is called the

efficient market hypothesis .On the other hand, studies made in the field of

behavioral finance tend to show that deviations from the fair price are rather common, and sometimes quite large.Fact|date=July 2008Thus, in addition to fundamental economic criteria, market criteria also have to be taken into account

market-based valuation . Valuing a stock is not only to estimate its fair value, but also to determine its**potential price range**, taking into account market behavior aspects. One of the behavioral valuation tools is thestock image , a coefficient that bridges the theoretical fair value and the market price.**On-line valuation calculators*** [
