What is PE Ratio:-
PE Ratio is Price to Earnings Ratio or Price to Earning Multiple. It is the ratio of a company’s share price to its earnings per share (EPS). EPS is calculated as the Company’s Net Income divided by the Total Number of outstanding shares.
PE Ratio = Companies Share Price ÷ EPS (Earning Per share)
The full form of EPS is Earning Per Share.
EPS = Company’s Net Profit ÷ Total Number of Outstanding Shares.

What the PE Ratio tells us:-
The PE ratio is the most widely used while determining the correct price valuation of Company’s stock. It helps investors to judge whether the stock is undervalued, overvalued, or fairly valued. PE Ratio is the number of times an investor is ready to pay as compared to its earnings. In simple terms, the PE Ratio is the price the investor is ready to pay to purchase Rs. 1 EPS of the company. PE Ratio is very useful in making the right investment decision.
In a broader sense, Higher PE Ratio indicates that the company’s stock is overvalued. A lower PE ratio indicates that it is fairly or undervalued. It is not thumb rule that a high PE ratio is always bad. High-performing company may have a high PE Ratio but it is not a bad idea to purchase that share because it is an exceptionally performing company. It is worth buying that company’s share even at a high PE Ratio. It is very easy to find the PE Ration of Stock by going to any financial website like Money Control, Groww, ET Money, or Zerodha.
Types of PE Ration:-
The most widely used PE Ratios are
- Forward PE Ratio: Current price of a share divided by projected future EPS of the company for 1 Year (4 Quarters)
- Trailing PE Ratio: Current price of a share divided by Trailing EPS of the last 1 year (4 Quarters).
The trailing PE Ratio is more accurate than the Forward PE Ratio because the Trailing PE Ratio is based on realistic past data. Whereas the Forward PE ratio is based on projected data. But both can be used for analyzing the stock valuation.
