What Is Price-to-Earnings Ratio – P/E Ratio?

The price-to-earnings ratio (P/E ratio) is the ratio for valuing a company that measures its current cốt truyện price relative to lớn its per-nói qua earnings (EPS).The price-to-earnings ratio is also sometimes known as theprice multipleor the earningsmultiple.

P/E rattiện ích ios are used by investors & analysts to determine the relative value of a company"s shares in an apples-to-apples comparison. It can also be used lớn compare a company against its own historical record or to lớn compare aggregate markets against one another or over time.

The price-earnings ratio (P/E ratio) relates a company"s chia sẻ price to its earnings per nói qua.A high P/E ratio could mean that a company"s stoông chồng is over-valued, or else that investors are expecting high growth rates in the future.Companies that have sầu no earnings or that are losing money vày not have a P/E ratio since there is nothing lớn put in the denominator.Two kinds of P/E ratios - forward and trailing P/E - are used in practice.

P/E Ratio Formula & Calculation

Analysts and investors nhận xét a company"s P/E ratio when they determine if the giới thiệu price accurately represents the projected earnings per mô tả. The formula and calculation used for this process follow.

P/ERatio=MarketvaluepershareEarningspershare extP/E Ratio = frac extMarket value per share extEarnings per shareP/ERatio=EarningspershareMarketvaluepershare​

To determine the P/E value, one simply must divide the current stock price by theearnings per nói qua (EPS). The current stoông xã price (P) can be gleaned by plugging a stock’s ticker symbol into any finance website, và although this concrete value reflects what investors must currently pay for a stochồng, the EPSis a slightly more nebulous figure.

EPS comes in two main varieties. The first is a metric listed in the fundamentals section of most finance sites; with the notation "P/E (TTM)," where “TTM” is aWall Streetacronym for “trailing 12 months.” This number signals the company"s performance over the past 12 months. Thesecond type of EPS is foundin a company"s earnings release, which often provides EPSguidance. This is the company"s best-educated guess of what it expects lớn earn in the future.

Sometimes, analysts are interested in long term 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 lớn gauge the overall value of a stock index, such as the S&P 500 since these longer term measures can compensate for changes in the business cycle. The P/E ratio of the S&P.. 500 has fluctuated from a low of around 6x (in 1949) to over 120x (in 2009). The long-term average P/E for the S&Phường 500 is around 15x, meaning that the stocks that ảo diệu the index collectively command a premium 15 times greater than their weighted average earnings.

Forward Price-To-Earnings

These two types of EPS metrics factor inkhổng lồ the most commontypes of P/E ratios:the forward P/E và thetrailing P/E. A third và less common variation uses the sum of the last two actual quarters and the estimates of the next two quarters.

The forward (or leading) P/E usesfuture earnings guidancerather than trailing figures. Sometimes called "estimated price to lớn earnings," this forward-looking indicator is useful for comparing current earnings to future earnings and helps provide a clearer picture of what earnings will look lượt thích – without changes and other accounting adjustments.

However, there are inherent problems with the forward P/E metric – namely, companies could underestimate earnings in order lớn beat the estimate P/E when the next quarter"s earnings are announced. Other companies may overstate the estimate và later adjust it going intotheir nextearnings announcement. Furthermore, external analysts may also provide estimates, which may diverge from the company estimates, creating confusion.

Trailing Price-To-Earnings

The trailing P/E relies on past performance by dividing thecurrent cốt truyện priceby the total EPS earnings over the past 12 months. It"s the most popular P/E metric because it"s the most objective sầu – assuming the company reported earnings accurately. Some investors prefer to look at the trailing P/E because they don"t trust another individual’searnings estimates. But the trailing P/E also has its mô tả of shortcomings –namely, a company’s past performance doesn’t signal future behavior.

Investors should thuscommit money based on futureearnings power, not the past. The fact that the EPS number remains constant, while the stock prices fluctuate, is also a problem. If a major company sự kiện drives the stochồng price significantly higher or lower, the trailing P/E will be less reflective sầu of those changes.

The trailing P/E ratio will change as the price of a company’s stoông chồng moves, since earnings are only released each quarter while stocks trade day in and day out. As a result, some investors prefer the forward P/E. If the forward P/E ratio is lower than the trailing P/E ratio, it means analysts are expecting earnings khổng lồ increase; if the forward P/E is higher than the current P/E ratio, analysts expect a decrease in earnings.

Valuation From P/E

Theprice-to-earnings ratioor P/Eis one of the most widely-used stochồng analysis toolsused by investors & analysts for determiningstoông chồng valuation. In addition to showing whether acompany"s stochồng price is overvalued or undervalued, the P/Ecan reveal how astock"s valuation compares khổng lồ its industry group or a benchmark lượt thích the S&Phường 500 Index.

In essence, the price-to-earnings ratio indicates the dollar amount an investor can expect khổng lồ invest in a company in order to lớn receive sầu one dollar of that company’s earnings. This is why the P/E is sometimes referred lớn as the price multiple because it shows how much investors are willing lớn pay per dollar of earnings. If a company was currently trading at a P/E multiple of 20x, the interpretation is that an investor is willing lớn pay $trăng tròn for $1 of current earnings.

The P/E ratio helps investors determinethe market value of a stochồng as compared to lớn thecompany"searnings. In short, the P/Eratio shows what the market is willing khổng lồ pay today for a stochồng based on its past or futureearnings. A high P/E could mean that a stock"s price is high relative lớn earnings and possibly overvalued. Conversely, a low P/E might indicate that the current stoông xã price is low relative sầu lớn earnings.

Example of the P/E Ratio

As a historical example, let"s calculate the P/E ratio for Walmart Stores Inc. (WMT) as of November 14, 2017, when the company"s stoông chồng price closed at $91.09. The company"s profit for the fiscal year ending January 31, 2017, was US$13.64 billion, and its number of shares outstanding was 3.1 billion. Its EPS can be calculated as $13.64 billion / 3.1 billion = $4.40.

Investor Expectations

In general, a high P/E suggests that investors are expecting higher earnings growth in the future compared lớn companies with a lower P/E. A low P/E can indicate either that a company may currently be undervalued or that the company is doing exceptionally well relative sầu to its past trends. When a company has no earnings or is posting losses, in both cases P/E will be expressed as “N/A.” Though it is possible khổng lồ calculate a negative sầu P/E, this is not the comtháng convention.

The price-to-earnings ratio can also be seen as a means of standardizing the value of one dollar of earnings throughout the stoông chồng market. In theory, by taking the median of P/E rattiện ích ios over a period of several years, one could formulate something of a standardized P/E ratio, which could then be seen as a benchmark and used khổng lồ indicate whether or not a stochồng is worth buying.

P/E vs. Earnings Yield

The inverse of the P/E ratio is the earnings yield (which can be thought of like the E/Phường ratio). The earnings yield is thus defined as EPS divided by the stoông xã price, expressed as a percentage.

If Stock A is trading at $10, and its EPS for the past year was 50 cents (TTM), it has a P/E of đôi mươi (i.e., $10 / 50 cents) & an earnings yield of 5% (50 cents / $10). If Stock B is trading at $trăng tròn và its EPS (TTM) was $2, it has a P/E of 10(i.e., $20 / $2) & an earnings yield of 10% ($2 / $20).

The earnings yield as an investment valuation metric is not as widely used as itsP/E ratio reciprocal in stock valuation. Earnings yields can be useful when concerned about the rate of return on investment. For equity investors, however, earning periodic investment income may be secondary to lớn growing their investments" values over time. This is why investors may refer to value-based investment metrics such as P/E ratio more often than earnings yield when making stoông xã investments.

The earnings yield is also useful in producing a metric when a company has zero or negative sầu earnings. Since such a case is comtháng among muốn high-tech, high growth, or start-up companies, EPS will be negative sầu producing an undefined P/E ratio (sometimes denoted as N/A). If a company has negative earnings, however, it will produce a negative earnings yield, which can be interpreted và used for comparison.

P/E vs. PEG Ratio

A P/E ratio, even one calculated using a forwardearnings estimate, don"t always tell you whether or not the P/E is appropriate forthe company"s forecasted growth rate. So, khổng lồ address this limitation, investorsturn to lớn another ratio calledthePEG ratio.

A variation on the forward P/E ratio is the price-to-earnings-to-growth ratio, or PEG. The PEG ratio measures the relationship between the price/earnings ratio& earnings growthlớn provide investors with a more complete story than the P/E on its own.In other words, the PEG ratio allows investorsto calculate whether a stock"s priceisovervalued or undervaluedby analyzing bothtoday"searnings & the expectedgrowth rate for the company in the future. The PEG ratio is calculated as a company’s trailing price-to-earnings (P/E) ratio divided by the growth rate of its earnings for a specified time period. The PEG ratio is used to lớn determine a stock"s value based on trailing earnings while also taking the company"s future earnings growth into trương mục, & is considered khổng lồ provide a more complete picture than the P/E ratio. For example, a low P/E ratio may suggest that a stoông chồng is undervalued & therefore should be bought – but factoring in the company"s growth rate khổng lồ get its PEG ratio can tell a different story. PEG ratquả táo can be termed “trailing” if using historic growth rates or “forward” if using projected growth rates.

Although earnings growth rates can varyamong muốn different sectors, a stochồng with aPEG of less than 1 is typically considered undervalued since its price is considered to be low compared lớn the company"sexpectedearnings growth. A PEG greater than1 might be considered overvalued since it might indicate the stock price is too highas compared lớn the company"sexpected earnings growth.

Absolute vs. Relative sầu P/E

Analysts may also make a distinction between absolute P/E và relative sầu P/E ratios in their analysis.

Absolute P/E

The numerator of this ratio is usually the current stoông xã price, và the denominator may be thetrailing EPS(TTM), the estimated EPS for the next 12 months (forward P/E) or a mix of the trailing EPS of the last two quarters & the forward P/E for the next two quarters. When distinguishing absolute P/E from relative P/E, it is important to lớn rethành viên that absolute P/E represents the P/E of the current time period. For example, if the price of the stoông chồng today is $100, & the TTM earnings are $2 per tóm tắt, the P/E is 50 ($100/$2).

Relative sầu P/E

The relative sầu P/E compares the current absolute P/E to a benchmark or a range of past P/Es over a relevant time period, such as the past 10 years. The relative sầu P/E shows what portion or percentage of the past P/Es the current P/E has reached. The relative sầu P/E usually compares the current P/E value to the highest value of the range, but investors might also compare the current P/E to the bottom side of the range, measuring how cthảm bại the current P/E is to lớn the historic low.

The relative P/E will have sầu 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 measure is 100% or more, this tells investors that the current P/E has reached or surpassed the past value.

Limitations of Using the P/E Ratio

Like any other fundamental designed to lớn insize investors on whether or not a stoông chồng is worth buying, the price-to-earnings ratio comes with a few important limitations that are important to lớn take into account, as investors may often be led to lớn believe that there is one single metric that will provide complete insight inkhổng lồ an investment decision, which is virtually never the case. Companies that aren"t profitable, & consequently have sầu no earnings—or negative sầu earnings per giới thiệu, pose a challenge when it comes to calculating their P/E. Opinions vary on how lớn giảm giá khuyến mãi with this. Some say there is a negative P/E, others assign a P/E of 0, while most just say the P/E doesn"t exist (not available—N/A) or is not interpretable until a company becomes profitable for purposes of comparison.

One primary limitation of using P/E ratgame ios emerges when comparing P/E ratquả táo of different companies. Valuations và growth rates of companies may often vary wildly between sectors due both to the differing ways companies earn money and to the differing timelines during which companies earn that money.

As such, one should only use P/E as a comparative sầu tool when considering companies in the same sector, as this kind of comparison is the only kind that will yield productive insight. Comparing the P/E ratquả táo of a telecommunications company & an energy company, for example, may lead one lớn believe sầu that one is clearly the superior investment, but this is not a reliable assumption.

Other P/E Considerations

An individual company’s P/E ratio is much more meaningful when taken alongside P/E ratios of other companies within the same sector. For example, an energy company may have a high P/E ratio, but this may reflect a trkết thúc within the sector rather than one merely within the individual company. An individual company’s high P/E ratio, for example, would be less cause for concern when the entire sector has high P/E ratquả táo.

Moreover, because a company’s debt can affect both the prices of shares and the company’s earnings, leverage can skew P/E rattiện ích ios as well. For example, suppose there are two similar companies that differ primarily in the amount of debt they take on. The one with more debt will likely have sầu a lower P/E value than the one with less debt. However, if business is good, the one with more debt stands khổng lồ see higher earnings because of the risks it has taken.

Another important limitation of price-to-earnings ratgame ios is one that lies within the formula for calculating P/E itself. Accurate & unbiased presentations of P/E rattiện ích ios rely on accurate inputs of the market value of shares and of accurate earnings per nói qua estimates. The market determines the prices of shares through its continuous auction. The printed prices are available from a wide variety of reliable sources. However, the source for earnings information is ultimately the company themselves.This single source of data is more easily manipulated, so analysts & investors place trust the company"s officers lớn provide accurate information. If that trust is perceived khổng lồ be broken the stoông xã will be considered more risky và therefore less valuable.

To reduce the risk of inaccurate information, the P/E ratio is but one measurement that analysts scrutinize. If the company were to lớn intentionally manipulate the numbers to look better, & thus deceive investors, they would have sầu to work strenuously to lớn be certain that all metrics were manipulated in a coherent manner, which is difficult to vị. That"s why the P/E ratio continues khổng lồ be one of the centrally referenced points of data lớn analyze a company, but by no means the only one.

Frequently Asked Questions

What is a good price lớn earnings ratio?

The question of what is a good or bad price to earnings ratio will necessarily depkết thúc on the industry in which the company is operating. Some industries will have higher average price to earnings ratquả táo, while others will have sầu lower ratgame ios. For example, as of January 20trăng tròn, publicly-traded US coal companies had an average P/E ratio of only about 7, compared to more than 60 for software companies. If you want lớn get a general idea of whether a particular P/E ratio is high or low, you can compare it to lớn the average P/E of the competitors within its industry.

Is it better to lớn have a higher or lower P/E ratio?

Many investors will say that it is better lớn buy shares in companies with a lower P/E, because this means you are paying less for every dollar of earnings that you receive sầu. In that sense, a lower P/E is like a lower price tag, making it attractive khổng lồ investors looking for a bargain. In practice, however, it is important khổng lồ underst& the reasons behind a company’s P/E. For instance, if a company has a low P/E because their business Mã Sản Phẩm is fundamentally in decline, then the apparent bargain might be an illusion.

What does a P/E ratio of 15 mean?

Simply put, a P/E ratio of 15 would mean that the current market value of the company is equal to 15 times its annual earnings. In other words, if you were lớn hypothetically buy 100% of the company’s shares, it would take 15 years for you lớn earn bachồng your initial investment through the company’s ongoing profits. requires writers to lớn use primary sources khổng lồ tư vấn their work.
