What is the PE ratio?

This is an acronym for price-to-earnings ratio.

When looking at two companies, we need to know which one is better we used the common measurement to compare the two

Example:

Company A and Company B
A sells shovels and is located in a snowy area
B sells shovels and is located in a sunny area

A makes 100,000
B makes 10,000

A has a share price of 60
B share price of 10

now we need to calculate the earnings per share
A has 50,000 outstanding shares
B has 10,000 outstanding shares

So A has an EPS of

EPS = {100,000 \over 50,000}.

And B has EPS of

EPS = { 10,000 \over 10,000}. 

Therefore: A has a P/E of:

PE = {60 \over 2} = 30.

And PE of B is:

 EPS = { 10 \over 1 } = 10 .

A has a higher EPS than B. The conclusion we can draw from the EPS is that B is a better stock to buy because it has a lower PE ratio. WHY?

  • because you are paying for the stock at a closer price to the earnings of said stock.
  • buying A means paying £60 times for a company earning £2 per share
  • and buying B means paying £10 for a company earning £1 per share

However:

P/E ratio is not the only indicator used when evaluating a stock, and for a good reason.
For instance, some stocks may have low PE ratio because they have limited growth potential.
I.e. company B selling snow shovels in a sunny area.

On the other hand, a high PE ratio is not always a bad indication, for instance, if A has invented a new type of shovel, this tech could increase demand for the shove,l and as a result, the company could grow quickly and increase earnings.
It would mean that, in this case, high PE ratio indicates greater expected growth opportunities.
So we would say that company A has high growth potential.

Take Away

  • PE is a measurement of a company’s price to earning per share.
  • the lower the PE ratio can be good for investors to maximise their buying power.
  • low PE also indicate limited growth potential
  • high PE can indicate high growth potential.
  • all these are dependent on the company and what value they provide. so it would be wise to use other metrics like dividends and future earnings to make your decisions.
