利用市盈率来进行估值虽然比较迅速,但由于只依靠简单的财务报表数据来估值,容易产生一些误差,容易忽略企业的负债经营的比重,盈余的质量是否可靠等因素。本文对市盈率的缺点进行了一定的改进,又考虑到普通投资者的时间和能力范围,提出了一个新的公式。希望能对广大投资者提供一个简单而又相对精确的估值方法。 The use of price-earnings ratio to carry out the valuation is relatively rapid, but only rely on simple financial statements to estimate the value, prone to some errors, easy to ignore the proportion of corporate debt management, the quality of the surplus is reliable and other factors. This paper makes some improvements to the shortcomings of price-earnings ratio, and puts forward a new formula considering the time and capacity of ordinary investors. Hope to provide investors a simple and relatively accurate method of valuation.
