What Is the Price-to-Earnings ( P/E ) Ratio ?
The price-to-earnings ( 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 store ‘s price is senior high school proportional to earnings and possibly overvalued. conversely, a low P/E might indicate that the current banal price is low relative to earnings. The P/E ratio helps investors determine the market value of a stock by measuring the current share price proportional to its earnings per share ( EPS ). Price-to-earnings proportion is sometimes besides known as the price multiple or the earnings multiple .
P/E ratios are used by investors and analysts to determine the relative value of a company ‘s shares in an apples-to-apples comparison. It can besides be used to compare a company against its own historical record or to compare aggregate markets against one another or over time.
Reading: Price-to-Earnings (P/E) Ratio
P/E may be estimated on a chase ( backward-looking ) or forward ( projected ) footing .
- The price-to-earnings (P/E) ratio relates a company’s share price to its earnings per share.
- A high P/E ratio could mean that a company’s stock is overvalued, or that investors are expecting high growth rates in the future.
- Companies that have no earnings or that are losing money do not have a P/E ratio because there is nothing to put in the denominator.
- Two kinds of P/E ratios—forward and trailing P/E—are used in practice.
- A P/E ratio holds most value when compared against similar companies in the same industry or compared for a single company across a period of time.
The Price To Earnings Ratio Explained
P/E Ratio Formula and Calculation
The formula and calculation used for this serve are as follows :
Understanding the P/E Ratio
The price-to-earnings proportion ( P/E ) is one of the most widely used tools by which investors and analysts determine a lineage ‘s relative evaluation. The P/E proportion helps one determine whether a lineage is overvalued or undervalued. A company ‘s P/E can besides be benchmarked against other stocks in the lapp industry or against the broader marketplace, such as the S & P 500 Index .
sometimes, analysts are concerned in long-run valuation trends and consider the P/E 10 or P/E 30 measures, which average the past 10 or past 30 years of earnings, respectively. These measures are often used when trying to gauge the overall value of a banal exponent, such as the S & P 500, because these longer-term measures can compensate for changes in the clientele cycle .
The P/E ratio of the S & P 500 has fluctuated from a abject of around 5x ( in 1917 ) to over 120x ( in 2009 right before the fiscal crisis ). The long-run average P/E for the S & P 500 is approximately 16x, meaning that the stocks that make up the index jointly command a premium 16 times greater than their weighted average earnings .
When to Review the P/E Ratio
Analysts and investors review a company ‘s P/E proportion to determine if the plowshare price accurately represents the project earnings per share.
These two types of EPS metrics divisor into the most common types of P/E ratios : the forward P/E and the trail P/E. A third gear and less common mutant uses the sum of the last two actual quarters and the estimates of the next two quarters .
The forward ( or leading ) P/E uses future earnings guidance rather than trailing figures. sometimes called “ estimated price to earnings, ” this advanced indicator is useful for comparing current earnings to future earnings and helps provide a clearer photograph of what earnings will look like—without changes and other accounting adjustments .
however, there are implicit in problems with the forward P/E metric—namely, companies could underestimate earnings in ordering to beat the estimated P/E when the next quarter ‘s earnings are announced. early companies may overstate the estimate and late adjust it going into their adjacent earnings announcement. furthermore, external analysts may besides provide estimates, which may diverge from the company estimates, creating confusion .
The trailing P/E relies on past performance by dividing the current contribution price by the total EPS earnings over the by 12 months. It ‘s the most popular P/E metric function because it ‘s the most objective—assuming the party reported earnings accurately. Some investors prefer to look at the trailing P/E because they do n’t trust another individual ’ sulfur earnings estimates. But the drag P/E besides has its partake of shortcomings—namely, that a caller ’ randomness past performance doesn ’ t signal future behavior .
Investors should thus commit money based on future earnings power, not the past. The fact that the EPS number remains changeless, while the stock prices fluctuate, is besides a trouble. If a major party consequence drives the livestock price significantly higher or lower, the trailing P/E will be less reflective of those changes .
The trailing P/E proportion will change as the price of a company ’ sulfur stock moves because earnings are lone released each quarter, while stocks trade day in and day extinct. As a result, some investors prefer the forward P/E. If the forward P/E proportion is lower than the trailing P/E proportion, it means analysts are expecting earnings to increase ; if the forward P/E is higher than the stream P/E ratio, analysts expect them to decrease .
evaluation From P/E
The price-to-earnings ratio or P/E is one of the most widely use stock analysis tools by which investors and analysts determine livestock valuation. In addition to showing whether a company ‘s stock price is overvalued or undervalued, the P/E can reveal how a banal ‘s evaluation compares to its diligence group or a benchmark like the S & P 500 Index .
In kernel, the price-to-earnings proportion indicates the dollar total an investor can expect to invest in a company in orderliness to receive $ 1 of that company ’ sulfur earnings. This is why the P/E is sometimes referred to as the price multiple because it shows how much investors are will to pay per dollar of earnings. If a company was presently trading at a P/E multiple of 20x, the interpretation is that an investor is will to pay $ 20 for $ 1 of current earnings.
case of the P/E Ratio
As a diachronic exemplar, let ‘s calculate the P/E proportion for Walmart Inc. ( WMT ) as of Feb. 3, 2021, when the company ‘s broth price closed at $ 139.55. The party ‘s earnings per plowshare for the fiscal class ending Jan. 31, 2021, was $ 4.75, according to The Wall Street Journal .
consequently, Walmart ‘s P/E ratio is $ 139.55 / $ 4.75 = 29.38 .
Comparing Companies Using P/E
As an extra exemplar, we can look at two fiscal companies to compare their P/E ratios and see which is relatively over- or undervalued .
Bank of America Corporation ( BAC ) closed out the year 2021 with the follow stats :
- Stock Price = $30.31
- Diluted EPS = $1.87
- P/E = 16.21x ($30.31 / $1.87)
In early words, Bank of America traded at roughly 16x trail earnings. however, the 16.21 P/E multiple by itself is n’t helpful unless you have something to compare it with, such as the standard ‘s industry group, a benchmark index, or Bank of America ‘s historic P/E range .
Bank of America ‘s P/E at 16x was slenderly higher than the S & P 500, which over time trades at about 15x trail earnings .
To compare Bank of America ‘s P/E to a peer ‘s, we calculate the P/E for JPMorgan Chase & Co. ( JPM ) as of the end of 2020 :
- Stock Price = $127.07
- Diluted EPS = $8.88
- P/E = 14.31x
When you compare Bank of America ‘s P/E of 16x to JPMorgan ‘s P/E of roughly 14x, Bank of America ‘s stock certificate does not appear american samoa 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 proportion might mean investors expected higher earnings growth in the future compared to JPMorgan and the overall market .
however, no individual proportion can tell you all you need to know about a stock. Before investing, it is wise to use a variety of fiscal ratios to determine whether a stock is fairly valued and whether a company ‘s fiscal health justifies its stock evaluation .

In general, a high P/E suggests that investors are expecting higher earnings growth in the future compared to companies with a lower P/E. A depleted P/E can indicate either that a company may presently be undervalued or that the company is doing exceptionally well relative to its past trends. When a ship’s company has no earnings or is posting losses, in both cases, the P/E will be expressed as N/A. Though it is potential to calculate a negative P/E, this is not the common convention .
A P/E proportion of N/A means the ratio is not available or not applicable for that company ‘s stock. A company can have a P/E ratio of N/A if it ‘s newly listed on the stock exchange and has not so far reported earnings, such as in the encase of an initial populace volunteer ( IPO ), but it besides means a company has zero or negative earnings, Investors can therefore interpret seeing N/A as a party reporting a internet personnel casualty. The price-to-earnings ratio can besides be seen as a mean of standardizing the value of $ 1 of earnings throughout the stock commercialize. In theory, by taking the median of P/E ratios over a period of several years, one could formulate something of a standardized P/E proportion, which could then be seen as a benchmark and used to indicate whether or not a stock certificate is worth buy .
P/E vs. Earnings give
The inverse of the P/E ratio is the earnings output ( which can be thought of as the E/P ratio ). The earnings return is therefore defined as EPS divided by the stock price, expressed as a share .
If Stock A is trading at $ 10, and its EPS for the past year was 50 cents ( TTM ), it has a P/E of 20 ( i.e., $ 10 / 50 cents ) and an earnings render of 5 % ( 50 cents / $ 10 ). If Stock B is trading at $ 20 and its EPS ( TTM ) was $ 2, it has a P/E of 10 ( i.e., $ 20 / $ 2 ) and an earnings yield of 10 % = ( $ 2 / $ 20 ) .
The earnings yield as an investment valuation metric function is not as widely used as its P/E proportion reciprocal cross in stock certificate valuation. Earnings yields can be useful when concerned about the rate of rejoinder on investment. For equity investors, however, earning periodic investment income may be secondary to growing their investments ‘ values over clock. This is why investors may refer to value-based investment metrics such as the P/E ratio more much than earnings concede when making livestock investments .
The earnings render is besides utilitarian in producing a metric function when a company has zero or negative earnings. Because such a case is common among high-tech, high-growth, or startup companies, EPS will be veto producing an undefined P/E ratio ( denoted as N/A ). If a party has negative earnings, however, it will produce a negative earnings move over, which can be interpreted and used for comparison .
P/E vs. PEG Ratio
A P/E proportion, even one calculated using a ahead earnings estimate, does n’t constantly tell you whether the P/E is allow for the party ‘s bode growth rate. sol, to address this limitation, investors turn to another ratio called the PEG proportion .
A variation on the forward P/E proportion is the price/earnings-to-growth ratio, or PEG. The PEG proportion measures the relationship between the price/earnings proportion and earnings increase to provide investors with a more complete report than the P/E can on its own. In other words, the PEG ratio allows investors to calculate whether a standard ‘s price is overvalued or undervalued by analyzing both today’s earnings and the expect emergence rate for the company in the future. The PEG ratio is calculated as a company ’ mho trailing price-to-earnings ( P/E ) proportion divided by the growth rate of its earnings for a specify meter period .
The PEG proportion is used to determine a stock ‘s value based on trailing earnings while besides taking the company ‘s future earnings growth into account and is considered to provide a more complete visualize than the P/E proportion can. For exercise, a low P/E proportion may suggest that a livestock is undervalued and consequently should be bought—but factoring in the company ‘s emergence rate to get its PEG proportion can tell a different floor. PEG ratios can be termed “ trailing ” if using historic growth rates or “ advancing ” if using stick out emergence rates .
Although earnings growth rates can vary among different sectors, a stock with a PEG of less than 1 is typically considered undervalued because its price is considered first gear compared to the company’s expected earnings growth. A PEG greater than 1 might be considered overvalue because it might indicate the stock price is excessively high compared to the company’s expected earnings growth .
Absolute volt. relative P/E
Analysts may besides make a distinction between absolute P/E and proportional P/E ratios in their analysis .
The numerator of this proportion is normally the current stock price, and the denominator may be the trail EPS ( TTM ), the calculate EPS for the future 12 months ( forward P/E ), or a mix of the trailing EPS of the end two quarters and the forward P/E for the adjacent two quarters .
When distinguishing absolute P/E from relative P/E, it is important to remember that absolute P/E represents the P/E of the current clock period. For example, if the price of the stock nowadays is $ 100, and the TTM earnings are $ 2 per partake, the P/E is 50 = ( $ 100 / $ 2 ) .
The relative P/E compares the current absolute P/E to a benchmark or a roll of past P/Es over a relevant fourth dimension period, such as the past 10 years. The proportional P/E shows what dowry or percentage of the past P/Es the current P/E has reached. The proportional P/E normally compares the current P/E measure to the highest measure of the range, but investors might besides compare the current P/E to the bottom slope of the rate, measuring how close the current P/E is to the historic depleted .
The proportional 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 ). If the relative P/E meter is 100 % or more, this tells investors that the stream P/E has reached or surpassed the past prize .
Limitations of Using the P/E Ratio
Like any other fundamental designed to inform investors as to whether or not a store is worth buy, the price-to-earnings ratio comes with a few authoritative limitations that are important to take into account because investors may frequently be led to believe that there is one individual metric that will provide complete insight into an investing decision, which is about never the case .
Companies that are n’t profitable and, consequently, have no earnings—or negative earnings per share—pose a challenge when it comes to calculating their P/E. Opinions vary as to how to deal with this. Some say there is a negative P/E, others assign a P/E of 0, while most just say the P/E does n’t exist ( N/A or not available ) or is not explainable until a company becomes profitable for purposes of comparison .
One primary limit of using P/E ratios emerges when comparing the P/E ratios of different companies. Valuations and growth rates of companies may much vary wildly between sectors due to both the different ways companies earn money and the differing timelines during which companies earn that money .
As such, one should lone use P/E as a comparative tool when considering companies in the same sector because this kind of comparison is the merely kind that will yield productive penetration. Comparing the P/E ratios of a telecommunications company and an energy party, for model, may lead one to believe that one is clearly the superior investment, but this is not a dependable premise .
other P/E Considerations
An individual ship’s company ’ sulfur P/E ratio is much more meaningful when taken aboard the P/E ratios of early companies within the like sector. For exemplar, an energy company may have a high P/E ratio, but this may reflect a tendency within the sector rather than one merely within the person company. An person company ’ mho high P/E proportion, for model, would be less cause for business when the entire sector has high P/E ratios .
furthermore, because a party ’ sulfur debt can affect both the prices of shares and the company ’ sulfur earnings, leverage can skew P/E ratios equally well. For example, suppose there are two exchangeable companies that differ primarily in the total 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 commercial enterprise is good, the one with more debt stands to see higher earnings because of the risks it has taken .
Another important restriction of price-to-earnings ratios is one that lies within the formula for calculating P/E itself. Accurate and unbiased presentations of P/E ratios trust on accurate inputs of the marketplace measure of shares and of accurate earnings per share estimates. The market determines the prices of shares through its continuous auction. The print prices are available from a wide-eyed assortment of reliable sources. however, the source for earnings information is ultimately the company itself. This one generator of data is more easily manipulated, so analysts and investors place trust in the company ‘s officers to provide accurate information. If that trust is perceived to be broken, the store will be considered riskier and therefore less valuable .
To reduce the hazard of inaccurate data, the P/E proportion is but one measurement that analysts scrutinize. If the party were to intentionally manipulate the numbers to look better, and frankincense deceive investors, they would have to work strenuously to be certain that all metrics were manipulated in a coherent manner, which is difficult to do. That ‘s why the P/E ratio continues to be one of the most centrally reference points of data when analyzing a caller, but by no mean is it the only one .
What Is a Good Price-to-Earnings Ratio?
The interrogate of what is a good or badly price-to-earnings proportion will necessarily depend on the industry in which the company is operating. Some industries will have higher modal price-to-earnings ratios, while others will have lower ratios. For model, in January 2021, publicly traded air companies had an average trail P/E proportion of alone about 12, compared to more than 60 for software companies. If you want to get a general idea of whether a particular P/E proportion is senior high school or low, you can compare it to the average P/E of the competitors within its industry .
Is It Better to Have a Higher or Lower P/E Ratio?
many investors will say that it is better to buy shares in companies with a lower P/E because this means you are paying less for every dollar of earnings that you receive. In that sense, a lower P/E is like a lower price chase, making it attractive to investors looking for a bargain. In rehearse, however, it is significant to understand the reasons behind a ship’s company ’ mho P/E. For exemplify, if a company has a low P/E because its business mannequin is basically in refuse, then the apparent dicker might be an magic trick .
What Does a P/E Ratio of 15 Mean?
Simply put, a P/E ratio of 15 would mean that the current marketplace value of the company is equal to 15 times its annual earnings. Put literally, if you were to hypothetically buy 100 % of the company ’ second shares, it would take 15 years for you to earn back your initial investment through the caller ’ randomness ongoing profits assuming the caller never grew in the future.

Why Is P/E Ratio Important?
The P/E ratio helps investors determine whether the livestock of a company is overvalued or undervalued compared to its earnings. The ratio is a measurement of what the market is volition to pay for the current operations a well as prospective growth of the company. If a company is trading at a high P/E ratio, the market thinks highly of its growth likely and is will to potentially overspend today based on future earnings .
