Most retail investors like feel that if a particular Company’s P/E is low than its Industry P/E, it would be good to buy the stock and sell when the P/E is higher.
P/E is an important ratio and its necessary while valuation of the company. P/E ratio helps us know the value that the Company holds. The problem with the P/E ratio is that it is majorly affected because of the sentiment, both positive and negative.
The numerator part P (Price) is not questionable while the denominator E (EPS - Earning per share) is on the historical performance of the Company.
