The PEG ratio is used to determine a stock’s value by comparing that to the company’s expected earnings growth. Referred to by the acronym BEER (bond equity earnings yield ratio), this ratio shows the relationship between bond yields and earnings yields. Some studies suggest that it is a reliable indicator of stock price movements over the short-term. The price-to-earnings ratio is most commonly calculated using the current price of a stock, although you can use an average price over a set period of time.
- Conversely, a low P/E could indicate that the stock price is low relative to earnings.
- The most well known example of this approach is the Shiller P/E ratio, also known as the CAP/E ratio (cyclically adjusted price earnings ratio).
- If a company trades at a P/E multiple of 20x, investors are paying $20 for $1 of current earnings.
- It doesn’t account for future earnings growth, can be influenced by accounting practices, and may not be comparable across different industries.
- To calculate the P/E ratio, compute the market value per share divided by the company’s earnings per share.
What Is the Difference Between Forward P/E and Trailing P/E?
For instance, if a company has a low P/E ratio because its business model is declining, the bargain is an illusion. A P/E ratio, even one calculated using a forward earnings estimate, doesn’t always tell you whether the P/E is appropriate for the company’s expected growth rate. To address this, investors turn to the price/earnings-to-growth ratio, or PEG. Earnings yields are gary cogley useful if you’re concerned about the rate of return on investment. For equity investors who earn periodic investment income, this may be a secondary concern. This is why many investors may prefer value-based measures like the P/E ratio or stocks.
All of our content is based on objective analysis, and the opinions are our own. As stated earlier, there is usually an acceptable range for the P/E ratio that must be researched and considered carefully for the purposes of investment. It is, therefore, also referred to as the earnings multiple and price multiple.

If a company’s stock is trading at $100 per share, for example, and the company generates $4 per share in annual earnings, the P/E ratio of the company’s stock would be 25 (100 / 4). To put it another way, given the company’s current earnings, it would take 25 years of accumulated earnings to equal the cost of the investment. The price-to-earnings ratio can also be calculated by dividing the company’s equity value (i.e. market capitalization) by its net income. One useful way to check if a stock’s PE ratio is reasonable is to also look at a related metric that incorporates the company’s earnings growth rate.
Either way, the P/E ratio would not be meaningful or practical for comparison purposes. To account for the fact that a company could’ve issued potentially dilutive securities accountants fort wayne in the past, the diluted share count should be used — otherwise, the EPS figure is likely to be overstated. For example, companies that have positive EPS can have negative free cash flow, meaning that they are spending more money than they earn despite being “profitable” based on accounting earnings. Many finance websites (including Stock Analysis) don’t show the PE ratio if EPS is negative because a negative PE ratio isn’t very informative.

For example, one-time writedowns and tax charges can sometimes make the EPS and PE ratio negative. Comparing the yields can give you a good idea of which one is a better long-term investment, although you should keep in mind that stocks are also much riskier than a savings account. If you want to compare the “yield” of different investments, then this may be a more useful number than the PE ratio.
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 (N/A) until a company becomes profitable. In general, a high P/E suggests that investors expect higher earnings growth than those with a lower P/E. A low P/E can indicate that a company is undervalued or that a firm is doing exceptionally well relative to its past performance.
When using a P/E ratio based on projected earnings (a forward P/E) there is a risk that estimates are inaccurate. For example, Tesla (TSLA) with a relatively high P/E ratio of 78 at the time of this writing, could be classified as a growth investment. General Motors (GM), with a current P/E ratio of 7, could be considered a value investment. The last alternative to consider is the enterprise value-to-EBITDA (EV/EBITDA) ratio.
In addition to indicating whether a company’s stock price is overvalued or undervalued, the P/E ratio can reveal how a stock’s value compares with its industry or a benchmark like the S&P 500. Investors often base their purchases on potential earnings, not historical performance. Using the trailing P/E ratio can be a problem because it relies on a fixed earnings per share (EPS) figure, while stock prices are constantly changing.
Earnings per share and the company’s overall P/E ratio may go negative briefly. While the P/E ratio is frequently used to measure a company’s value, its ability to predict future returns is a matter of debate. The P/E ratio is not a sound indicator of the short-term price movements of a stock or index. There is some evidence, however, of an inverse correlation between the P/E ratio of the S&P 500 and future returns. Therefore, the market is currently willing to pay $10 for each dollar of earnings generated by the company.
The price divided by earnings part of the P/E ratio is simple and consistent. Get instant access to video lessons taught by experienced investment bankers.

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. Therefore, similar to all other financial metrics, the price-to-earning ratio (P/E ratio) should not be used alone to make investment decisions. If a company borrows more debt, the EPS (denominator) declines from the higher interest expense.
This chart from multpl.com shows how the CAPE ratio has changed over time. Generally speaking, a low PE ratio indicates that a stock is cheap, while a high ratio suggests that a stock is expensive. Some investors also prefer to use N/A, or else report a value of 0 until the EPS is positive.
