A bstract The traditional cash flow model of stock pric ing in the process of the invest ment can not precisely determine profitability and future payment of cash dividend. Corporate equity (stock) has the characteristics of the o ption, and the stock of pany is essentially a call option based on corporate value, the price of which is the amount of debt servicing when pany bond expire s, and we can use the option pricing model for stock pric ing . This method does not need to estimate the future cash dividend and the expected rate of return of invest ment , which e s the ings of the traditional methods ina certain extent. First ly, we review the stock pricing methods at domestic and foreign enterprises. Then we introduce two classical model s in the stock market: cash flow model and dividend discount model, and analyses the advantages and disadvantages of each model and its scope. At last, we study stock pricing model s based on Black – Scholes ’ theoretical research and Binomial tree model s. We use the methods of the theoretical analysis--empirical analysis -- advantages and disadvantages analysis to analyze the model . According to empirical analysis, we make e valuation ofe nterprise v alue and verif y the accuracy of the evaluation based on the theory of stock option pricing model. Finally, compar ing to the two models we draw a conclusion how to make the stock pricing .
