That may indicate the market thinks XYZ will generate lower earnings growth as compared to the average company in the S&P 500. In practice, the P/E ratio is a widely used valuation multiple but has its limitations in being affected by differing reporting standards, growth rates, and the capital structure of the companies being compared. The first part of the P/E equation or price is straightforward because the current market price of a stock is easily obtained, but determining an appropriate earnings number can be more difficult. Investors must determine how to define earnings and the factors that impact earnings. There are some limitations to the P/E ratio as a result as certain factors impact the P/E of a company. One primary limitation of using P/E ratios emerges when comparing the P/E ratios of different companies.
Companies with a low Price Earnings Ratio are often considered to be value stocks. It means they are undervalued because their stock prices trade lower relative to their fundamentals. This mispricing will be a great bargain and will prompt investors to buy the stock before the market corrects it. Examples of low P/E stocks can be found in mature industries that pay a steady rate of dividends.
What is P/E Ratio?
If a manufacturing company requires $50 in capital to produce $1 in earnings, then it shouldn’t be worthy of the same ratio as a technology company that requires just $3 in capital to produce $1 in earnings. The P/E ratio is useful, but don’t rely only on this ratio for your stock purchase decisions. There are companies with low P/E ratios for which the P/E ratio will drop even more, and vice versa.

Investors and traders should keep in mind that PEG ratios aren’t necessarily comparable because of the varying assumptions that may be used in this ratio’s calculation. The P/E ratio is used to provide insight into the value of a given company, or the market as a whole.
If you think a company has a superior business but it still has a low P/E ratio, then it may be a good investment. For young, fast-growing companies, a negative P/E may not necessarily be the most important determinant when it comes to overall valuation. For example, one analyst may estimate the earnings growth rate over a 1-year period, using one set of assumptions. While another analyst may estimate the growth rate over a 1-year period, using a different set of assumptions. It’s also possible that XYZ’s industry/sector trades with a lower average P/E as compared to other market sectors, and that XYZ’s P/E of 12 times earnings is appropriate, and in-line with its peers.
What Is a Relative Valuation?
When you compare Bank of America’s P/E of 16x to JPMorgan’s P/E of roughly 14x, Bank of America’s stock does not appear as overvalued as it did when compared with the average P/E of 15 for the S&P 500. Bank of America’s higher P/E ratio might mean investors expected higher earnings growth in the future compared to JPMorgan and the overall market. The P/E ratio can tell you a great deal about what investors overall think of a given stock. In addition, there can be situations where a company has a low P/E ratio simply because its future earnings prospects are dim. This can create a “value trap,” where a stock looks cheap by comparison but demonstrates in the future that there was a reason for its low price. Enthusiasm on the part of investors can lead to P/E expansion—a period when investors’ perceptions of a company improve, and as a result, they are willing to pay more for a dollar’s worth of earnings.
On the other end of the spectrum, if investors feel that future earnings will be underwhelming, a stock’s P/E ratio may languish at a relatively low level. As a result of all this, companies and industry groups generating the same level of earnings per share can be awarded very different P/E ratios. For example, two companies may both report earnings of $2 per share, but the stock trading at $20 a share has a P/E ratio of 10 while the other trading at $30 a share has a P/E of 15.
How is the price-earnings ratio calculated for multiple years?
The price to earnings ratio can also be calculated by dividing the company’s equity value (i.e. market capitalization) by its net income. The PEG ratio measures the relationship between the price/earnings ratio and earnings growth to provide investors with a more complete story than the P/E alone. Earnings per share (EPS) is the amount of a company’s profit allocated to each outstanding share of a company’s common stock. Earnings per share is the portion of a company’s net income that would be earned per share if all profits were paid out to its shareholders. EPS is typically used by analysts and traders to establish the financial strength of a company. Moreover, because a company’s debt can affect both the prices of shares and the company’s earnings, leverage can skew P/E ratios as well.
- Companies with low — say, below 1 — P/E-to-earnings-growth (PEG) ratios may be worth somewhat higher P/E ratios.
- Its broker-dealer subsidiary, Charles Schwab & Co., Inc. (Member SIPC), offers investment services and products, including Schwab brokerage accounts.
- Trading securities, futures products, and digital assets involve risk and may result in a loss greater than the original amount invested.
- A high P/E ratio indicates that investors are willing to buy the shares of the company at a higher price.
- If a growth stock is trading at its highest-ever P/E ratio, but the growth rate is starting to decline, then the stock’s price may soon fall.
It means little just by itself unless we have some understanding of the growth prospects in EPS and risk profile of the company. An investor must dig deeper into the company’s financial statements and use other valuation and financial analysis methods to get a better picture of a company’s value and performance. The PEG ratio allows investors to calculate whether a stock’s price is overvalued or undervalued by analyzing both today’s earnings and the expected growth rate for the company in the future. In essence, the price-to-earnings ratio indicates the dollar amount an investor can expect to invest in a company in order to receive $1 of that company’s earnings. This is why the P/E is sometimes referred to as the price multiple because it shows how much investors are willing to pay per dollar of earnings.
What if a company’s P/E ratio is lower than its industry average?
A company’s P/E can also be benchmarked against other stocks in the same industry or against the broader market, such as the S&P 500 Index. The P/E ratio helps investors determine the market value of a stock as compared to the company’s earnings. In short, the P/E ratio shows what the market is willing to pay today for a stock based on its past or future earnings. A high P/E could mean that a stock’s price is high relative to earnings and possibly overvalued.
Example of the P/E Ratio
For example, suppose there are two similar companies that differ primarily in the amount of debt they assume. The one with more debt will likely have a lower P/E value than the one with less debt. However, if the business is good, the one with more debt stands to see higher earnings because of the risks it has taken. The trailing P/E ratio will change as the price of a company’s stock moves because earnings are only released each quarter, while stocks trade day in and day out. If the forward P/E ratio is lower than the trailing P/E ratio, it means analysts are expecting earnings to increase; if the forward P/E is higher than the current P/E ratio, analysts expect them to decrease.
Limitations to the P/E Ratio
In the next step, one input for calculating the P/E ratio is diluted EPS, which we’ll compute by dividing net income in both periods (i.e. LTM and NTM basis) by the diluted share count. Using a P/E ratio is most appropriate for mature, low-growth companies with positive net earnings. To account for the fact that a company could’ve issued potentially dilutive securities in the past, the diluted share count should be used — otherwise, the EPS figure is likely to be overstated. Every investor wants an edge in predicting a company’s future, but a company’s earnings guidance statements may not be a reliable source. The relative P/E will have a value below 100% if the current P/E is lower than the past value (whether the past high or low).
