Here in the above photo we have seen how to calculate PE ratio. If we compare stock A and stock B, we can understand which stock can be a profitable choice for us in the future.
Stock B has lower PE ratio so we have to pay less for every rupee of earnings. Stock B is undervalued so stock B is more likely to rise in price than stock A in the future.
Stock A is trading at a low price but Stock A has a high PE ratio which indicates that the stock is overvalued which indicates that the stock may go down in the future.
In short, If the PE ratio is high, the stock\’s price will be higher than its earnings and is considered overvalued. If the PE ratio is low, the stock will be worth less than its earnings and is considered undervalued.

What is PB Ratio?
The PB ratio is also a valuation ratio but it uses the book value of the company instead of earnings. Book value means that a company\’s book value is the total assets it has after deducting its liabilities from its account.

If PB ratio > 1, so stock is overvalued and PB ratio < 1, So stock is undervalued. If the PB ratio is less than one, it means that if the company were to sell all its assets in the market, it would be able to sell for more than the book value. Due to such reasons investors always invest in stocks with low PB ratio.
Here the PB ratio of stock A is 1.66 and the PB ratio of stock B is 2 which indicates that stock B is overvalued.
