What is PE Ratio?

The price-to-earnings ratio can be a trailing PE multiple. For this, the earnings of the previous twelve months are computed.  Alternatively, it can be a forward price-to-earnings ratio. Forward PE is calculated by dividing the prospective earnings in the upcoming months by the price per stock.

Key Takeaways

  • The price-to-earnings ratio is the proportionate value of a share’s market price and earnings. It shows the number of times the earnings need to be invested in a stock. Calculation: PE Ratio = Price Per Share/ Earnings Per Share. The trailing price-to-earnings ratio is based on past earnings, while the forward price-to-earnings ratio depends on the forecast of future earnings. The analysts correlate a company’s PE multiple with the PE multiples of competition within the industry. This way, the appropriate valuation of a share is ascertained.

PE Ratio Explained

The price-to-earnings ratio is a measure that reflects an organization’s potential to make money. This potential is measured in terms of the value paid by equity holders for each stock unit. Thus, it indicates if a particular stock is cheaper or costlier than its competitors within the same industry. Additionally, the current price-to-earnings ratio can be compared to the company’s past ratios to track its growth. The price-to-earnings ratio can be of two different forms trailing price-to-earnings multiple and the forward price-to-earnings ratio.

This is the most common equity multipleEquity MultipleEquity multiple refers to the growth potential of an asset or investment measured in the number of times the current value is of the initial investment. It is computed as the present value of a property divided by the amount invested.read more. An equity multiple is a metric that calculates the expected or achieved total returnTotal ReturnThe term “Total Return” refers to the sum of the difference between the opening and closing value of all the assets over a particular period of time and the returns thereon. To put it simply, the changes in opening and closing values of assets plus the number of returns earned thereof is the Total Return of the entity over a period of time.read more on an initial investment. The price-to-earnings ratio is widely used for measuring equity because of data availability. This is especially the case with historical earnings and forecasted earnings.

In addition, the Price-to-earnings ratio has an advantage of discounted cash flow valuation (DCF) technique; it is not sensitive to assumptions. In DCF, changes in WACC or growth rate assumptions can dramatically change the valuations. Therefore price-to-earnings ratio is extensively used for comparing companies within a sector.

 Also, the effort required for this valuation methodValuation MethodDiscounted cash flow, comparable company analysis, comparable transaction comps, asset valuation, and sum of parts are the five methods for valuing a company.read more is relatively less. In contrast, a typical DCF model may take 10-15 days of the analyst’s time. For the same valuation, a comparable PE comp can be prepared within hours.

PE Ratio Formula

The price-to-earnings ratio is primarily derived from the payback multiple. The Payback multiple is the time required to recover initial costs and expenses.

Similarly, the PE ratio is the number of yearly share earnings it will take an investor to recover the price paid for the share.

For instance, if the PE multiple is 10x. It implies that for each $1 of earning, the investor has paid $10. Hence, it will take ten years of earnings for the investor to recover the price paid.

It is computed as:    

PE Ratio Calculation

The calculation of price to earnings ratio of any company involves the following three steps:

  • Finding the market price of each share of the company: This information can be availed from NASDAQ and other stock exchangeStock ExchangeStock exchange refers to a market that facilitates the buying and selling of listed securities such as public company stocks, exchange-traded funds, debt instruments, options, etc., as per the standard regulations and guidelines—for instance, NYSE and NASDAQ.read more where the company is listed. This value fluctuates constantly.  Locating or evaluating the per-share earnings of the company: The organization’s profit or revenues, whether historical or forecast, can be found on the websites like Bloomberg, Reuters, Yahoo Finance, etc. Alternatively, PE ratio can be calculated by dividing the company’s net profit (profit after taxProfit After TaxProfit After Tax is the revenue left after deducting the business expenses and tax liabilities. This profit is reflected in the Profit & Loss statement of the business.read more) by the number of outstanding common stocks.Applying the PE formula and calculating the PE ratio: Lastly, divide the price per stock (as in step 1) by the earnings per shareEarnings Per ShareEarnings Per Share (EPS) is a key financial metric that investors use to assess a company’s performance and profitability before investing. It is calculated by dividing total earnings or total net income by the total number of outstanding shares. The higher the earnings per share (EPS), the more profitable the company is.read more (determined in step 2) to get the PE multiple.

Further, after getting the PE value of a firm, the analyst can compare it with other organizations and past PE multiples.

For example, as of December 31, 2020, the stock price of XYZ Inc. was $197.42. The company has earnings per share of $1.39 in 2020. Now, figure out its price-to-earnings for 2020. Let us assume there is another company ABC Ltd. whose PE ratio is 211.17. Now, find out which investment opportunity of the two is more beneficial.

Given:

  • Price per share = $197.42Earnings per share = $1.39PE Ratio = Price Per Share/ Earnings Per SharePE Ratio = 197.42/ 1.39PE Ratio = 142.03

This means an investment of $142.03 in XYZ Inc. will yield $1. The price-to-earnings of ABC Ltd. is 211.17, while that of XYZ Inc. is 142.03. This indicates that if investors invest in XYZ Inc, they can generate the same earnings by investing 69.14 times less.  Clearly, XYZ Inc. is a better option.

PE Ratio Examples

#1 – Price to earnings ratio of Colgate compared to the industry

Now let us take a real-world example to compare the PE Ratio of one company with the other companies of the sector.

Let us look at the PE multiple of Colgate and its comparison with the industry.

Here, Colgate’s price-to-earnings ratio is 44.55x; however, the Industry’s Price Earnings Ratio is 61.99x. Clearly, Colgate is outperforming. So naturally, investors would prefer paying $44 to earn 1$ instead of paying $62 to earn the same.

#2 – PE Ratio of Tesla Inc.

Tesla Inc. has a price-to-earnings multiple of 407.05 at present, while its forward price-to-earnings ratioForward Price-to-earnings RatioForward PE ratio uses the forecasted earnings per share of the company over the next 12 months for calculating the price-earnings ratio. Forward PE ratio formula = Price per share/Projected earnings per share read more for 2022 is 223.41.

How to Find Target Price using Price to Earnings Ratio?

Target Price is what we expect the stock price to be, say at the end of 2016 or 2017.

Let us look at another PE Ratio Example.

Let us assume that WallStreetMojo is operating in Services Sector along with its peers – AAA, BBB, CCC, DDD, EEE, FFF, GGG, HHH.

In order to find the Target Price of WallStreetMojo, we need Average Trailing PE values and Forward PE values. The Average Trailing PE Ratio is 56.5x, and the Forward PE Ratios are 47.9x and 43.2x, respectively.

WallStreetMojo’s Target Price = EPS (WallStreetMojo) x Forward PE Ratio

Let us assume that WallStreetMojo 2016E and 2017E EPS are $4 and $5, respectively.

Based on the PE multiple formulae above,

  • WallStreetMojo 2016E Target price = $4 x 47.9 = $191.6WallStreetMojo 2016E Target price = $5 x 43.2 = $216

Theoretically, the Target Prices look good. But, practically speaking, the Target Prices look all wrong. Why is that so?

Target pricesTarget PricesPrice Target in the context of stock markets, means the expected valuation of a stock in the coming future and the valuation may be done either by the stock analysts or by the investors themselves. For an investor, price target reflects the price at which he will be willing to buy or sell the stock at a particular period of time or mark an exit from their current position.read more look all wrong due to the presence of outliers in the Comparable Table prepared. Please note that HHH has a Price Earnings Ratio closer to 200x. There could be various reasons for the high Price Earnings Ratio of HHH; however, we are here to find the appropriate target price for WallStreetMojo.

For finding the Correct Target Price, we need to remove outliers like HHH, revise the Comparable Table, and find the new average PE multiple. Then, using these modified PE Ratios, we can re-calculate the Target Price.

Target Price PE Example

  • Revised WallStreetMojo 2016E Target price = $4 x 17.2 = $68.8Revised WallStreetMojo 2016E Target price = $5 x 18.2 = $91

A good price-to-earnings ratio is the one that is lower than the price-to-earnings multiple of competing firms, the whole industry, or the previous ratios of itself. In other words, the PE multiple is the number of times one pays for yielding a dollar. The stock is more affordable to an investor if the number is lower.

As of October 04, 2021, the trailing-twelve-month price to earnings ratio of the S&P 500 is 33.54. This value is based on its current market price and recent earnings.

The price to earnings ratio of any company gauges its market valuation.  A stock with a higher PE multiple signals its overvaluation. However, considering other factors like debt, business model, and industry’s performance can help discover the reasons behind the PE figures.
