Price Earnings Ratio Formula, Examples and Guide to P E Ratio

P/E ratio, or the Price-to-Earnings ratio, is a metric measuring the price of a stock relative to its earnings per share (EPS). The P/E ratio is important as it helps you identify whether the stock is overvalued or undervalued. Index funds mimic the stock markets, and hence, their prices represent the stock market’s state of overvaluation or undervaluation. So if the P/E ratio of an index like the NIFTY 50 goes down to, let’s say 18, 17, 15, or thereabouts, we have enough data to suggest that it will revert back to its mean of 20 eventually. 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.

Some investors also prefer to use N/A, or else report a value of 0 until the EPS is positive. Looking at PE ratios and rejigging your portfolio can be a lot of work, and most people avoid this hassle. Generally, a lower P/E ratio is considered good, while a higher P/E ratio is considered bad. Similarly, let’s look at another example where you own an apartment and give it out on rent.

It is calculated by dividing the current share price by the estimated earning per share for the next twelve months. A PEG greater than one might be considered overvalued because it suggests the stock price is too high relative to the company’s expected earnings growth. The price-to-earnings (P/E) ratio is one of the most widely used tools that investors and analysts use to determine a stock’s valuation. The P/E ratio is one indicator of whether a stock is overvalued or undervalued.

1. The P/E ratio would be a significantly large multiple and not be comparable to industry peers (i.e. as a complete outlier) — or even come out to be a negative number.
2. Trailing P/E ratio (the most widely used form) is based on the earnings of the previous 12 months, while the forward P/E ratio uses forecasted earnings.
3. Importantly, there is no single metric that can tell you whether a stock is a good investment or not.
4. Whether a company’s P/E ratio is acceptable or not for the purpose of investment can be determined by comparing it with that of other similar companies or the industry’s average ratio.
5. The relative P/E compares the absolute P/E to a benchmark or a range of past P/Es over a relevant period, such as the past 10 years.

Price Earnings Ratio FAQs

A company whose P/E ratio seems to accurately value the stock is generally the safer option, rather than risking money on a stock that seems over or undervalued. As such, when looking at the stock of a particular company, it is more useful to evaluate the P/E ratio of that company against the industry average rather than the market average. The average P/E ratio of the NIFTY 50 lies between 20 to 25, and if the P/E ratio of the company exceeds this range, it is considered overvalued.

Different types of PE ratios

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. The P/E ratio indicates the dollar amount an investor can expect to invest in a company to receive $1 of that company’s earnings. Hence, it’s sometimes called the price multiple because it shows how much investors are willing to pay per dollar of earnings.

However, the P/E ratio can mislead investors, because past earnings do not guarantee future earnings will be the same. The P/E ratio, often referred to as the “price-earnings ratio”, measures a company’s current stock price relative to its earnings per share (EPS). The P/E ratio also helps investors determine a stock’s market value compared with the company’s earnings. That is, the 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 ratio could signal that a stock’s price is high relative to earnings and is overvalued. Conversely, a low P/E could indicate that the stock price is low relative to earnings.

It is necessarily an estimate, and as such is sometimes called an “estimated P/E ratio”. A simple way to think about the P/E ratio is how much you are paying for one dollar of earnings per year. There is no straightforward rule for a P/E ratio to be classified as good or bad, as it can vary depending on the industry, economic conditions, and investors’ preferences. For example, suppose you own a bookstore, which earns you an annual profit of Rs. 5 lakh.

Because a company’s debt can affect both share price and earnings, leverage can skew P/E ratios as well. The firm with more debt will likely have a lower P/E value than the one with less debt. However, if the business is solid, the one with more debt could have higher earnings because of the risks it has taken. 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.

How confident are you in your long term financial plan?

P/E ratios are most useful in comparing similar companies within a sector or industry. We can now determine the P/E ratios by dividing the share price by the EPS. Firstly, we’ll calculate the earnings per share (EPS) by using the earnings figures and the number of outstanding shares issued.

It means they are undervalued because their stock prices trade lower relative to their fundamentals. This mispricing will be a great bargain and will prompt investors to buy the stock before the market corrects it. And when it does, investors make a profit as a result of a higher stock price. Examples of low P/E stocks can be found in mature industries that pay a steady rate of dividends. Companies with a high Price Earnings Ratio are often considered to be growth stocks. This indicates a positive future performance, and investors have higher expectations for future earnings growth and are willing to pay more for them.

How Do I Calculate the P/E Ratio of a Company?

A P/E ratio of 15 means that the company’s current market value equals 15 times its annual earnings. Put literally, if you were to hypothetically buy 100% of the company’s shares, it would take 15 years for you to earn back your initial investment through the company’s ongoing profits. However, that 15-year estimate would change if the company grows or its earnings fluctuate.

The PEG ratio is calculated as a company’s trailing price-to-earnings (P/E) ratio divided by its earnings growth rate for a given period. By showing the relationship between a company’s stock price and earnings per share (EPS), the P/E ratio helps investors to value a stock and gauge market expectations. Analysts use this ratio to determine if a company’s current share price is overvalued or undervalued compared with its earnings per share. If the P/E is high, they consider it overvalued and recommend that investors wait for their stock price to drop before purchasing. If the P/E is low, they consider it undervalued and recommend that investors buy their stock since its price will likely increase in the future. Another critical limitation of price-to-earnings ratios lies within the formula for calculating P/E.

However, no single ratio can tell you all you need to know about a stock. Before investing, it is wise to use a variety of financial ratios to determine whether a stock is fairly valued and whether a company’s financial health justifies its stock valuation. However, the 18.92 P/E multiple by itself isn’t helpful unless you have something to compare it with, such as the stock’s industry group, a benchmark index, or Bank of America’s historical P/E range. It is essential to consider other valuation metrics and evaluate the company’s future growth prospects. You calculate the PE ratio by dividing the stock price with earnings per share (EPS). Earnings yield is defined as Earnings Per Share (EPS) divided by the stock price.
