Some investors use financial statements to

create ratios that can help compare the performance of similar companies. In this video, you'll learn how investors

can use the P/E ratio to help compare the valuation of two or more companies. Let's look at an example. Suppose there are two companies that both

make and sell snow shovels. Company A is trading for $60 per share, while

Company B is trading for $10 per share. A new investor might assume the $10 stock

is the best value because it's the cheapest. But this isn't necessarily true. A low share price does not mean a stock is

undervalued. A stock is considered undervalued when its

price is low relative to the amount of money the company earns, rather than compared to

the price per share of similar companies. To help compare these two companies and determine

which may be the better value, we need a common measurement, such as the price-to-earnings,

or P/E, ratio. The P/E ratio simply compares a stock's

price to its company earnings, or profit.

Now, back to our example. Let's say Company A is located in Wisconsin,

which gets a lot of snow. Therefore, Company A sells a lot of shovels

and earns a profit of $100,000 a year. Company B is located in Texas. While Texas is a big state with a high population,

it doesn't receive much snow. Therefore, Company B only earns a profit of

$10,000 a year. We know each stock's share price and each

company's earnings, but we don't know how many shares have claim on the earnings. To put it another way, we need to know how

many shares the company has issued to calculate the value of each share relative to the company's

overall earnings.

This calculation is known as earnings per

share, or EPS. Because Company A has 50,000 outstanding shares

and $100,000 in earnings, each share has a claim on an EPS of $2. Now that we have Company A's EPS, we can

calculate the P/E ratio. At a price of $60 per share and an EPS of

$2, Company A's P/E ratio is 30. This means its stock is trading at 30 times

its earnings per share. Let's calculate Company B's P/E ratio. It has 10,000 outstanding shares and $10,000

in earnings, resulting in an EPS of $1. The stock is at $10 per share, which means

Company B is trading at 10 times its earnings or has a P/E ratio of 10. In this example, Company B may be a better

value, not because it has a lower stock price, but because it has a lower P/E ratio.

In other words, the lower the P/E, the less

an investor is paying per dollar of a company's earnings. Although the P/E ratio is the most common

valuation measurement, it isn't the only indicator that should be used when evaluating

a stock. For instance, some stocks may have low P/E

ratios because they have limited growth potential. If Company B only sells snow shovels in a

state where there isn't much snow, then it isn't as likely to grow.

However, if both companies are expected to

grow at similar rates, then Company B could be the better value based on its P/E ratio. Also keep in mind that a high P/E ratio isn't

always bad. For example, suppose Company A is doing well

because it invented a new shovel that pushes itself. This new technology could increase demand

for its shovels, and the company could grow very quickly and potentially increase earnings. This kind of growth could justify a high P/E

ratio. In this case, a high P/E ratio could indicate

greater expected growth opportunities. If you expect earnings to grow, the current

price may be worth the investment. The P/E ratio is a commonly used and versatile

fundamental analysis tool because it can help investors identify value and growth stocks. Just remember to compare price and earnings,

and to keep earnings potential and other factors in mind when evaluating stocks. Because the P/E ratio only factors in earnings

per share and price, investors should consider using other metrics like dividends or projected

future earnings to help determine a stock investment's potential.
