Client: Okay, But I believe we should be careful while thinking about this. 

What do you feel about the PE ratio or What is PE ratio? Well, After reading this post you will be super clear about PE ratio meaning, PE ratio means, and also you will be to identify nifty PE ratio. 

Introduction of PE Ratio

Price to Earning The PE ratio, sometimes referred to as the company’s earnings price multiple or the earnings multiple is calculated by dividing the stock price at the time by the EPS, or earnings per share. The majority of investors are aware of this financial ratio, which is maybe the most well-known. The market’s perception of a company’s earning potential and long-term business prospects is reflected in its PE ratio. High PE ratios are typically demanded by businesses that enjoy strong investor confidence and a strong market position. For instance, blue-chip corporations and a few high-growth midcap firms have P/E ratios between 20 and 60. However, the majority of India’s small- and mid-cap enterprises have a PE ratio between 5 and 20. It would appear, on the surface, that businesses with low PE ratios would present the most alluring investment prospects. However, you also need to take EPS into account. Let’s express PE Ratio in a mathematical expression. 

PE Ratio = Price of a Share/ Earning Per Share

Now you want to know about EPS.

It is the profit that the business makes on a share that an investor purchases. Mathematically, we may write it as follows:

EPS is an acronym for earnings per share.

As an illustration, the business XYZ Ltd. has a profit of Rs. 20,00,000 and a total of 5,00,000 shares.

XYZ Ltd.’s EPS is then 4.

It indicates that the corporation is earning Rs. 4 on each share. Regardless of the share price. The firm receives this Rs.4, not the stockholders.

Deep Down and Making of PE Ratio

As we get closer to creating the PE ratio formula, we now ask for your undivided attention for the next two to three minutes. Assuming, of course, that the firm’s earnings remain constant, the PE ratio may be thought of as the number of years it will take the company to earn back the amount of your initial investment. Let’s imagine you paid Rs. 4,000 to purchase 100 shares of ABC Ltd. Given the current profits per share of Rs. 4, your 100 shares will yield Rs. 400 in a year, and your initial Rs. 4,000 investment will be recovered in 10 years.

The PE ratio of every firm can be found on Google, so you don’t have to go through this laborious calculation. Simply prefix the firm name with “price to earning” or “pe ratio.”

Purchasing stock in a firm with a price to earnings ratio of two will allow you to recoup your initial investment in two years, but purchasing stock in a company with a pe ratio of 40 will need you to wait forty years to do the same.

Any firm that is reasonably valued will have a PE ratio that is equal to its growth rate. Here, we’re referring to the growth rate of earnings. The growth rate and PE ratio can also be compared. If it’s PE is 16, you would anticipate that ITC will increase at a rate of around 16% yearly, etc. However, you could have found a good offer if the PE ratio is lower than the growth rate. According to us, a purchase with a PE ratio of 6-7 and business growth of 16 is quite appealing. On the other hand, a PE ratio of 16 is not a wise investment if the growth rate is 6-7 percent yearly. A PE ratio that is half the pace of growth is extremely favorable, while one that is double the rate of growth is quite unfavorable. When examining equities for investment prospects, we frequently utilize this metric.

Intrepretation of the PE Ratio

A thorough examination of PE Ratios for numerous sectors and company types is so monotonous. Avoid stocks with very high PE Ratios if you recall nothing else about them. If you do, you’ll save yourself a tonne of trouble and money. We can recall a business with a PE ratio of 122.
To recoup your investment would take one century and twenty-two years.

Fair value is defined as a company’s PE ratio falling between 12 and 18, and if the ratio exceeds 19, there might be several factors at play. The business can be overpriced or have promising prospects. Some novice investors would haphazardly buy-in firms with low PE ratios; we believe that this approach is absurd for elite investors. As you compare the two businesses using PE, take in mind that they should be in the same industry. 


Even in the Olympics wrestlers in the same weight category fight against each other. You won’t see a match between a 60Kg Guy and an 80Kg Guy. They also use terminologies like Lightweight, Heavyweight, etc.

You can’t compare TATA MOTORS PE Ratio with INFOSYS PE Ratio since one company is operating in Automobile Sector and another one is in IT Sector. 

Comparing INFOSYS PE with TCS PE is a fair match.
