市盈率估值模型的投资应用分析

An Inquiry into the Application of the Price to Earning Ratio Evaluation Model in Investment Analysis

市盈率=普通股每股市价／每股收益。该模型是用来衡量股票定价是否合理、判断股市投资 价值的一种常用方法。投资者用市盈率指标能粗略地分析、评价股票价值和投资风险。但是,该指标有 其不可避免的局限性,投资者在投资应用中还应综合其他相关因素进行分析,才能有效发挥市盈率对投 资的指导意义,从而做出正确的投资决策。

Price to earnings ratio=Market value per share of common / Earnings of per share. This model is used to measure if the stock price is reasonable and to verify the investment value of the stock market. Using the price to earnings ratio, the investor can roughly analyze and evaluate the value of the stock and the investment risk. However, the price to earnings ratio has its own shortcomings. The investor, thus, should take other factors into account so as to make the best decision.
