Price to Earnings (PE) Ratio
The price to earnings ratio is the most fundamental of all market related ratios. It has been used for decades by stalwarts in the investment community. However, it is also the ratio that has come under maximum fire from the skeptics. A variety of measurements have been developed to compensate for what skeptics call the lack of correct information provided by the price earnings ratio. Almost all other market related ratios are a variation of the price to earnings ratio.
Formula
Price to Earnings Ratio = Current Market Price / Reported Earnings of the Company
Meaning
The price to earnings ratio tells the investors how many rupees they are paying for every rupee in earnings that the company presently has. If the price to earnings ratio is 5, then investors are paying 5 rupees to get a stream of earnings of 1 rupee per year till perpetuity. This ratio therefore also implicitly tells the payback period which in this case would be 5 years.
Assumptions
There are a lot of assumptions that the price to earnings ratio implicitly makes. This is the reason that this ratio has come under a lot of criticisms from skeptics who think that price to earnings ratio provides a distorted image of what the reality of the company really is. The common assumptions are as follows:
Interpretation
The price to earnings ratio must be interpreted in the light of the fundamentals of finance. These fundamentals are the fact that an investment grows over a period of time. This growth pattern usually follows an exponential pattern which makes the phenomenon of compounding so important.
The fact that price to earnings ratio uses simple arithmetic division makes it unacceptable to many skeptics in the investment community.
