Using the Price-to-Earnings P E Ratio and PEG Ratio to Assess a Stock

The company’s price-to-earnings ratio is 10x, which we determined by dividing its current stock price by its diluted earnings per share (EPS). In essence, a higher P/E ratio indicates investors expect higher growth from the company in the future compared to companies with a lower P/E. For example, a given stock may trade at a lower earnings multiple because it is expected to grow its earnings at a slower rate than the average company in the S&P 500.

A tech stock with a P/E of 25x is not necessarily overpriced if competitors all have similar P/Es. Higher P/E ratios are often justified for companies expected to deliver above-average earnings growth. More than a company’s P/E ratio is needed to determine if a stock will be profitable to an investor.

Since the P/E ratio is a financial metric that works parallel to other ratios and metrics, it’s important to understand these contributing factors when calculating and using it. The stock market is a foreign concept to many, but those who participate try to find any means to evaluate and understand the profitability of stocks. Earnings reports, profit margins, ROA, and the Price-to-Earnings ratio help investors understand the value of a stock better. 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. As such, one should only use P/E as a comparative tool when considering companies in the same sector because this is the only kind that will provide worthwhile results.

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 to calculate a negative P/E, this is not the common convention.

One reason for a high P/E ratio is that investors have optimism about the company’s future growth potential. Investors are willing to pay more for shares today because they believe earnings will grow substantially over time. Companies like technology and biotech stocks often have high P/E ratios due to their potential for expansion.

How do you analyze a stock using the P/E ratio?

A company with a P/E of 40x but forecasted to grow earnings at 40% per year is sometimes reasonably valued. Slow-growing companies command lower industry typical P/Es, such as 10-12x. Looking at a stock’s historical P/E range over a 5-10-year period provides a helpful perspective. A P/E well above the normal range likely signals overvaluation, while a P/E below historical norms means possible undervaluation. Sudden surges in valuation often revert back toward the average eventually. The forward P/E ratio (or forward price-to-earnings ratio) divides the current share price of a company by the estimated future (“forward”) earnings per share (EPS) of that company.

In general, PEG ratios under 1.0 are preferred, as that may imply that the company in question is undervalued relative to its future earnings potential. A PEG ratio above 1 suggests the opposite—that a company may be overvalued as compared to its future earnings potential. The PEG ratio can be a valuable complement to the P/E ratio because it factors in a company’s expected earnings growth. The PEG ratio is often used in concert with the P/E ratio to assess the relative value of a company. For example, some industries trade with higher price multiples, as compared to others.

The P/E ratio also does not reflect balance sheet health, cash flows, dividends, buybacks and other important financial factors. The P/E ratio can be impacted by non-recurring events, which sometimes do not reflect real operating performance. Events like asset sales, inventory liquidations, tax law changes, and restructuring costs artificially impact earnings used in P/E ratios.

Earnings Power and Future Earnings Guidance

1. Calculating a company’s P/E ratio may initially seem complex, but it’s easy to understand once you understand a few fundamental concepts.
2. Get instant access to video lessons taught by experienced investment bankers.
3. The P/E ratio should be analyzed in the context of a company’s financials, growth prospects, industry peers, and broader market valuations.
4. Finding the true value of a stock cannot just be calculated using current year earnings.
5. Conversely, a low P/E ratio could mean the stock is undervalued or the company’s growth prospects are weak.
6. This is possible because while the market price of stock can’t be negative, the earnings per share of a company can be negative.
7. The P/E ratio is just one of the many valuation measures and financial analysis tools that we use to guide us in our investment decision, and it shouldn’t be the only one.

In practice, however, there could be reasons behind a company’s particular P/E ratio. For instance, if a company has a low P/E ratio because its business model is declining, the bargain is an illusion. Like any other fundamental metric, the price-to-earnings ratio comes with a few limitations that are important to understand. Companies that aren’t profitable and have no earnings—or negative earnings per share—pose a challenge for calculating P/E. 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. 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.

1. When used properly and in context, the P/E ratio can aid investors in identifying potential value opportunities.
2. Along with the many tools, the Price-to-Earnings ratio directly ties into whether or not stocks are over or undervalued.
3. Companies with a high Price Earnings Ratio are often considered to be growth stocks.
4. How a company does this depends on the market and its business strategies.
5. Investors and traders sometimes interpret the earnings yield as the amount of earnings one receives for each dollar invested in the company’s shares.
6. A high P/E ratio could signal that a stock’s price is high relative to earnings and is overvalued.
7. Similar companies should be compared to each other, like insurance to insurance or oil producer to oil producer.

These non-recurring items should be normalized before using the earnings in the P/E analysis. Also, break down how much of the earnings growth is coming from margin expansion versus revenue growth to assess the quality of earnings. Higher margins could flag potential issues like underinvestment in R&D or customer squeeze. Strike provides real-time data on key metrics like the price-to-earnings ratio for any publicly traded company. With Strike, you will be able to quickly look up the latest P/E ratio for any stock just by searching for the ticker symbol. The P/E should be assessed alongside profit margins, debt levels and other factors to judge earnings quality.

Similar companies within the same industry are price to earnings ratio formula grouped together for comparison, regardless of the varying stock prices. Moreover, it’s quick and easy to use when we’re trying to value a company using earnings. When a high or a low P/E is found, we can quickly assess what kind of stock or company we are dealing with. Investors want to buy financially sound companies that offer a good return on investment (ROI).

The Financial Modeling Certification

The P/E ratio is popular and easy to calculate, but it has shortcomings that investors should consider when using it to determine a stock’s valuation. Finding the true value of a stock cannot just be calculated using current year earnings. The value depends on all expected future cash flows and earnings of a company. 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 P/E ratio also helps investors determine a stock’s market value compared with the company’s earnings.
